The feature-rich MicroFlex e150 drive is expected to be popular among OEM machine builders as it offers a remarkably flexible platform for making new machinery designs.

“Machinery OEMs need versatile products, and these new drives have versatility in abundance – without needing to add hardware or choose configuration options,” said David Greensmith of ABB.

“The multi-protocol Ethernet capability and local intelligence mean that the applications potential is truly broad. And the processing performance is spectacular too – offering some 20 times the speed of one of our popular existing generations of smart drives – making it ideal for performance intensive applications such as high-speed labeling.”

ABB said that the new MicroFlex e150 drives are ideally suited for numerous machine automation applications, such as grinding or glue laying, metal cutting machinery (plasma/waterjet) and various common packaging automations that include form/fill/seal. The drives also feature multi-tasking programmability and two high speed registration inputs, making it suitable for speed-intensive applications like labeling.

In addition, the drives can also be fitted with a scalable PLC platform for automation applications, the AC500 PLC. The PLC communicates using a wide range of standard fieldbuses such as EtherCAT, which is an Ethernet based protocol.

The axis’ main head moves left to right and up and down on the cross beam to make the table turn front to rear. All of the axes are driven by double-nut ball screws of high precision to stop thermal increase while machining. Offering an outstanding repeatability and positioning, the double pretension design also provides practically no thermal increase. Reducing any backlash, all ball screws are directly linked to the servo drive motors avoiding the need for belts or gears.

The linear motion guideways help achieve fast axis movement trimming on machining time and non-cutting time. The spindle traverse for the A/C axes is 70/150 rpm while for the X/Y/Z axes is 50/50/50 m/min.

Hi-Mold VMC’s main spindle is engineered for precision machining delivering 24,000 rpm, geared with precision-class angular bearings offering fast acceleration or deceleration. Even at the greatest rotation levels, the spindle maintains low vibration, reducing thermal transmission to the main spindle and therefore, promoting stability.

An optional 40,000-rpm main spindle is offered for high-quality machining of mold cavities and bases. To ensure that oil temperature remains constant and to reduce the growth in the spindle caused by heat distortion, it also gets a spindle oil chiller that can control the spindle temperature.

Unlike other competitive servo driven hydraulics, the machine’s two-platen clamp design allows it to directly apply pressure to the mold’s center rather than the corners, resulting to more consistent parts.

In a release, Milacro’s Hydraulic Platform Product Manager Brian Bish noted that the new Maxima Servo line combine the energy savings of various all-electric presses with its small footprint and two-platen’s center tonnage cylinder. The company also revealed that the energy savings offer a return on the initial cost premium for at least six months.

Instead of utilizing an induction motor that operates at a fixed speed, Maxima’s servomotors runs at varying speeds of zero to 3000 rpm in both directions and respond to work load with remarkably high resolution. This is attributed to its ability to control rotation by a fraction of an angle.

Moreover, the electro-hydraulic pump is replaced by an internal gear pump, which offers the advantage of running only when needed and requires less maintenance.

The Maxima directly provides clamping force behind the mold by centrally positioning the tonnage cylinder at the back of the moving platen, effectively concentrating uniform force at the mold surface and reducing platen deflection. Aside from reducing mold wear, this also enables superior force distribution across the parting lines of the mold for cleaner parts.

Offered globally from 310 tons to 4400 tons, the Milacron Maxima Servo is also available in hybrid version.

Delivering over twice the power of standard servomotors, the new HW series liquid-cooled servomotors also offer optimized dynamic performance. The Kent-based company has included the cooling jacket without significantly increasing the motor housing’s size, while improving the 190 frame models’ output power to 29 kW and the stall torque to 134 Nm. This means that the company has increased the power density by almost three-fold as compared to standard air-cooled servomotors with similar flange-size.

“In developing these liquid-cooled servomotors we have addressed a number of issues that were being raised by customers,” said Steve Jackson, Sales and Marketing Manager at SEM.

“In particular, where motors are used in precision applications, such as machine tools, they may wish to limit the heat that the motor generates and, in turn, maintain a steady ambient temperature. This will help to overcome problems associated with temperature fluctuations during operation of machines that may be working to micron tolerances.”

Compatible with the company’s current motors, the newest range of liquid-cooled servomotors are offered with standard flanges. In addition, customers can select various feedback devices, including precision encoders and resolvers.

The motor’s dynamic performance makes it ideally suited for use in high-speed positioning and packaging systems, punch presses and servo pump drives.

Motion Control Tips

Such systems are said to offer greater reliability mainly because there are fewer parts to connect together. Also, fewer external connections means less cabling and wiring. Less cabling and wiring reduces costs, as does the fact that the components that one would usually purchase separately such as the motion controller and the drive are integrated into one package.

These integrated servomotors are also designed to be programmed easily and quickly, which can help reduce development times. Communication options range from simple serial communication links such as RS232 or RS485 to more advanced network topologies suited to complex motion control tasks such as CANopen, DeviceNet, or Ethernet protocols.

As with any motor, when selecting an integrated servomotor for an application, the most important step is determining the characteristics of the load. This is why properly calculating the load torque is such an important part of selecting the right motor and designing it into the application. A good rule of thumb to keep in mind is to try and keep the actual operating conditions below the published limits of the motor in order to ensure reliable and long-life operation.

Motor sizing parameters are usually based on the torque curve and moment of inertia of the load. These two factors can help determine the motor’s operating bandwidth. Sets of torque curves depict limits of both continuous and peak torque for the given motor over their full range speed.

There are different types of torque curves, dealing with peak torque and continuous torque as well. Peak torque curves can be derived from dyno testing and represent the point at which peak current limit hardware settings of the drive prevent further torque in an effort to protect drive stage components.

For any mechanical system, if the motor is operating in its optimum range, then the system will be performing at its best. Beyond the motor itself, depending on the specifics of the application it may be necessary to adjust mechanical components such as gear reducers, belts, lead screw pitch or pinion gears in order to achieve optimal system performance.

Motion Control Tips

All servomotors have essentially three components; an electric motor, a feedback device, and some type of electronic control.

The electric motor itself can be either an ac or a dc motor. Under the dc heading, brushed dc servomotors are generally less expensive than brushless servos, but do require more maintenance due to the brushes needed for motor commutation.

Brushless servomotors are more expensive than brushed dc motors. Generally, these are used in applications requiring higher torque. Brushless dc servomotors are highly reliable and virtually maintenance free. However, the drives for brushless dc servomotors are more complex because the commutation is done electronically rather than mechanically as in the brushed dc motor.

Another way to classify servomotors can be as either single-phase or three-phase motors. Motors of the single-phase variety can range from the simple and inexpensive brushed dc motors mentioned above to voice coils for small micro- and nano-positioning applications.

Servomotors also require a form of feedback, often with the feedback device, such as an encoder, built right into the motor frame. The feedback signal is needed by the control circuitry to close the control loop. It is this closed-loop control that gives servomotors their precise positioning ability.

Lastly, the control circuitry typically involves a motion controller, which generates the motion profile for the motor, and a motor drive which supplies power to the motor based on the commands from the motion controller.

Servomotors are used in many different industrial applications from machine tools, packaging machinery, communications and robotics applications to newer applications such as solar panel control and a broad range of automation control applications. The diversity of applications means that servomotors are designed for general-purpose indoor environments but also for specialized situations requiring them to withstand extreme temperatures and pressures outdoors as well as the special demands of food processing industries in washdown environments.

Motion Control Tips

A servo controller is the heart of a servo system. A typical servo system consists of a motor, feedback device, and the controller. The control circuitry typically involves a motion controller, which generates the motion profile for the motor, and a motor drive which supplies power to the motor based on the commands from the motion controller. Servo systems are closed-loop systems which have some benefits over open-loop systems including the fact that they improve transient response times, reduce steady state errors and reduce system sensitivity to load parameters.

Servo controllers perform two types of tasks; tracking some commanded input and improving a system’s disturbance rejection. One of the most powerful methods of control is PID control, which stands for proportional-integral-derivative control. PID control is a combination of proportional control, integral control and derivative control. A PID control method works on the error signal which is the difference between a commanded value and the actual value of an output variable, and driving the error to zero. The proportional value can be thought of as a simple gain value. The integral value integrates the error over a period of time and helps to drive the error to zero. The derivative value helps to stabilize a system that uses an integral and proportional term only.

There are a few important factors to consider when selecting a servo controller for an application. The first thing is knowing which type of motor is to be controlled. Is the servomotor an ac or dc motor? If dc, is it brushless or brushed? This will help in determining the kind of commutation the motor needs and if the controller can accommodate it.

How many axes of motion does the application have? Is it a single axis of control or are there multiple axes? Servo controllers are available to control simple single axis applications as well as more complex motion such as robotics applications involving multiple axes.

Next, how many channels of I/O are needed? Are special input types needed beyond inputs for feedback signals such as speed and position? Be sure that the controller can accommodate the appropriate feedback device, such as incremental encoder signals, resolver signals, SSI, Hall sensor signals, or tachometer inputs.

Another important factor that is sometimes overlooked is the controller set up. Is the controller easy to set up and program? Is programming done via keypad or can it be programmed from a computer screen? Also consider the available communication links. Are there basic RS232 or RS485 links? Does the controller include bus interfaces for common networks such as CAN, DeviceNet, Sercos or Ethernet?

The direct drive technology eliminates belts, down-gearing and unnecessary linkages, while offering the shortest distance of transmission to maximize torque distribution. The servo presses feature Point-On-Demand (P.O.D.) controller with eight preset stroke profiles such as multiple hits in one stroke, pendulum strokes, free-hand programmability and extended dwell time. SEYI eliminates the issue of power surges and higher power requirements through its innovative energy-saving storage system.

The ribbed frame construction of the servos effectively reduces deflection and provides more rigidity, particularly during longer dwells. With the hydraulic overload replaced with a programmable electronic overload, the servos offer more stable protection when operating closer to rated tonnage for longer periods.

SEYI’s servo presses seamlessly combined the advantages of the programmable slide of hydraulic press with mechanical press speed. This provides manufacturers greater control in speed, tonnage and dwell at any stage of the entire stroke, allowing them to better utilize exotic materials, form more complicated geometric parts, and eliminate various secondary operations. The dwell profiles enable stampers to prevent materials from springing back and produce higher quality parts.

Programming slow ram velocity during the single stroke’s working portion, and fast ram speeds at die-opening and die-closing segments generates increased production rates while lowering reverse load, vibration and stamping noise, and prolonging die maintenance cycle.

Rockwell Automation provided the control solution that would enhance the flexibility and performance of Thiele’s Nigrelli Envoy Tray Former Packer, a continuous-motion, high-speed packaging system specifically designed for loading cartons, bottles and cans onto corrugated trays, pads or U-board. Processing up to 3,600 containers per minute with exceptionally accurate positioning and versatility, the heart of the Envoy features Rockwell Automation Kinetix Integrated Motion solution that includes an Allen-Bradley ControlLogix controller, Allen-Bradley MP-Series servo motors and Allen-Bradley Kinetix 6000 multi-axis servo drives. Together they control and coordinate all major machine functions, such as placing and carrying the trays through the machine, and control of the rotary tray and feeding system.

Rockwell Automation’s ControlLogix controller eliminates the need for multiple programming packages and controllers, conveniently tying all control functionality into one, multitasking controller platform. Motion functions of the Envoy are incorporated in both the Rockwell Software RSLogix 5000 programming software and the ControlLogix controller. To reduce time spent on wiring, engineers utilized a SERCOS interface module for integration with the Kinetix 6000 servo drives. Operators of the Envoy can view the status and performance parameters of the machine through an Allen-Bradley PanelView Plus 1000 touch-screen human-machine interface.

The RSLogix 5000 software’s motion instructions reduce the need to coordinate and write two programs in separate controllers.

“With the need for high reliability and fast changeovers, the servo control technology from Rockwell Automation provided the best option,” said Stephen Kaye, Rigid Product Line Manager at Thiele Technologies.

The cross-lapper uses a light weight fiber web, which it accepted from the carding machine, to build a heavier web in layers. The cross-lapper then overlaps the layers through a group of reversing mobile carriages and conveyors that turn the material through 90°.

ABB’s machinery drives and servomotors are harnessed by Tatham’s TSX control system with various panel combinations, depending on the current cross-lapper configurations used.

Tatham’s system is connected to the main process control using Profibus, through which an ABB AC500 PLC delivers positioning data to the drives that gives control signals for the speed control of the servomotor.

“We chose ABB drives because of their versatility, power and competitive pricing,” said Tatham’s Senior Electrical Engineer Jim Kelly.

“Together with ABB, we developed control software based on their drives’ programmable function blocks, which meant we had a system that provided precise positioning … resulting in total control of the batt profile,” he added.

“Heaviness of the batt is a function of the speed it is laid down at, and using the ABB PLC, drives and servomotors allows us to vary this precisely, giving a much more accurate and controllable build up of the layers.”

Aside from ensuring fiber savings, the TSX control system is also energy efficient. Prior to installation of the ABB drives the cross-lapper utilized 60A peak, but after the installation the current has been significantly reduced to 15A.

The new interface enables one cable to carry both encoder signal and power. Motors now require a single connector only, which significantly reduces costs and cabling time.

For safe speed and position functions, the Hiperface DSL encoder interface has been specifically designed to be the only interface that supports encoders to SIL3 levels.

Using two or four wires within a motor’s power cable, digital sensor data can be transmitted on a maximum distance of 100 m. Although commonly used for motor winding temperature sensors, the twisted-wire pair wires can now be utilized for digital communications. Encoders compatible with the new protocol are provided with an optional input which digitize temperature signals and transmit them directly to the drive containing the encoder data.

Standard cables can be used when transmitting data at a distance of up to 20 m. For longer distances, the cables must conform to specified impedance criteria.

Offering a transmission rate of 9.216 Mbd, the new interface conforms with RS-485 criteria. It transmits data in a short span of 12.15 μs, or five times faster than the fastest drives.

“The combination of improved speed regulation and functionality with greater operator safety, and at a reduced cost, marks a significant step forward,” said Darren Pratt, encoder specialist at Sick UK.

“Hiperface DSL is set to be the new standard for high- to low-performance applications.”

The new encoders can also be used to log speed, temperature and rotation data for maintenance purposes. Hiperface DSL can also include other sensor information — such as vibration, acceleration and torque — to offer optimized dynamic control.

Motion Control Tips

In order to save weight, installation space and the amount of mass being moved, gearboxes are mounted directly on the motor. This new mounting system was made possible by totally reconstructing the motor’s output flange and adapting it completely to the gearboxes. The center gear rests directly on the motor shaft and replaces the input shaft on the gearbox. This type of mounting renders an adapter flange, the clamp system and the gearbox input bearing obsolete. In addition to an approximately 20% savings in weight and installation space, the amount of mass that has to be moved is considerably reduced as well.

Because of the rigid structure and the small amount of mass, high-performance control loops can be created for dynamic applications, even in tight spaces.

With gearboxes that are mounted directly on the motor, it’s possible to select between the 8GM30 economy series, the 8GM40 standard gearboxes and the 8GM50 reinforced gearboxes.

Gearboxes in the standard series are available as single-stage and two-stage units with a backlash <8- <15 arcminutes. The 8GM50 series uses bearings optimized for radial and axial forces for mechanical compatibility with Wittenstein products.

With the characteristics mentioned above, this series is optimally suited for applications that place the highest demands on dynamics and torque when limited space is available.

The company now aims to provide high-frequency welders ranging from 30 kHz to 50 kHz for smaller medical parts such as ports, valves, implant components and filters.

Meanwhile, Dukane’s larger press platform (super 20 kHz and 15 kHz) aims to cater to larger part sizes for medical applications. Dukane’s new welders feature new Melt Match technology, which offers stronger welds, greater repeatability, lower manufacturing cost and easier calibration versus standard pneumatic welders.

“We’ve expanded our iQ servo welding line beyond the existing 20 kHz model and now offer wide-ranging capabilities and flexibility to meet the unique and diverse requirements of our customers,” said Michael Johnston, National Sales and Marketing Manager.

The company’s smaller press systems ranging between 600 watts to 1800 watts are ideal for high-speed automation and higher throughput. Its larger press platform delivers higher wattage ranging between 3300 watts to 5000 watts and higher clamping force.

Complementing the company’s latest collection of iQ servo-controlled ultrasonic welding systems, the new models utilize a unique method that accurately controls the collapse speed profile while welding. This technology eliminates the problem of collapsing too fast, which often results in cold forming and collapsing too slow, which may cause degradation of materials, by precisely matching the collapse speed during the melt phase resulting in larger heat zone and deeper ultrasonic propagation into the bond area and ultimately in superior bond strength.

The company’s portfolio of iQ servo welders is FDA CFR Title 21 Part 11 compliant and features ultra-rigid support base and a strong mechanical design.

The high-performance servo motors offer high power density in a small installation space and integrate all electrical and mechanical elements into a very compact unit.

Designed with a very small absolute encoder system offering a resolution of 262144 steps per revolution, the system can achieve high precision while occupying lesser space.

The gearboxes are directly mounted on the motor to save installation space, weight and the amount of mass being moved, made possible by a total reconstruction of the motor’s output flange and its adoption to the gearboxes.

The center gear directly rests on the motor shaft and substitutes the input shaft on the gearbox. This kind of mounting eliminates the need for a clamp system, adapter flange or the gearbox input bearing.

Aside from saving approximately 20% in installation space and weight, it also reduces the amount of mass that has to be moved.

Creating high-performance control loops for dynamic applications is also possible even in tight spaces with the small amount of mass and rigid structure.

With gearboxes directly mounted on the motor, it is possible to choose from the standard 8GM40 gearboxes, the economy series 8GM30 gearboxes and the reinforced 8GM50 gearboxes.

The 8GM50 series uses optimized bearings for axial and radial forces for mechanical compatibility with Wittenstein products.

The latest motor series is suited for applications with high demand on torque and dynamics in limited spaces.

Machines today require better energy efficiency and increased productivity and availability. They also expect improvement in cost effectiveness throughout its life cycle. But these expectations are not met in the case of low-efficiency standard motors or hydraulic systems and maintenance-intensive gearboxes.

Baum’s new generation of torque motors score with an extended range of speeds and a significantly improved power density. The torque range of the current product line has also been significantly increased. The motor series’ extension to include a 400-size motor means that rated torques up to 20,000Nm and maximum torques up to 32,000Nm are possible. This not only significantly increases productivity in existing applications but also opens up new application areas.

The new product line requires less installation space, thereby minimizing the contact surface for machines. Since torque motors have practically no residual torque, customers can improve the smooth running characteristics and the quality of its products to achieve a significant competitive advantage. Finally, its price-to-performance ratio increases the cost-effectiveness for customers.

“It was fun,” Matthew Koniecko, who is in the eight-grade and the design and engineering leader of the team. “Difficult in some way, but it’s mostly fun.” The team first made cardboard prototypes to test the design, throwing away many ideas that did not work, he said. The last design features plywood wheels, a swiveling grasping claw and an extendable arm made of PVC pipes.

It is the first time that the school has participated in a robotics competition, and its young team competed against older and more experienced students from Montville, Waterbury, Stony Brook, Long Island and other areas. The students competing were all in sixth grade through 12. The team from Sacred Heart comprised of two eighth-graders, one seventh-grader and four sixth-graders.

Christine Wasielewski, a Sacred Heart teacher of enhancement and religion who coached the team, was overwhelmed. “We had to basically cut everything out ourselves. The students looked at the brain component, with the BEST joystick and the controller and the little servo motors, and they said, ‘Oh, we could do this,’” she said.

“We were very, very good at the cone competition, and that was our strategy,” said Mrs. Wasielewski. Mrs. Katherine Muller, the school’s principal, claimed that the team was very happy just to have a working robot when the competition started.

The self-contained Microgravity Demonstrator has a motion controlled drop tower that accelerates objects to 32ft/sec², simulating a free-fall, micro-gravity condition that matches the weightlessness experienced when traveling in space or orbiting the Earth. Through a slow motion video camera system, the students can observe five experiments in weightless conditions at brief periods.

Hydrotech’s servo-controlled system uses motion automation solution to overcome the negative impact of friction that would usually occur in a free-fall experiment. “It took over four months to design, develop and program the motion profiles needed for simulating a frictionless acceleration and deceleration in free fall,” said David Sopko, an engineer at Hydrotech. “A nearly instantaneous accel-decel was key to extending weightless conditions for the time duration required to observe the microgravity experiments in an earth-bound classroom setting.”

Aided by the motion control engineering team from Hydrotech, Paragon Tech has designed six Microgravity Demonstrators for universities with two more units on order so far. “This unit applies motion control engineering and AC servo motor technology that Hydrotech typically provides for advanced industrial automation systems,” Sopko added. “Who would have thought that our expertise could be used to help educate and excite the next generation of space explorers.”
