Connecting the feedback and power cables enables the motor to run and deliver a maximum torque of 4,500 rpm.

With system parameters set on system power up, Junma’s machine load inertia is automatically calculated, while its tuning gains are dynamically adjusted, even during load changes, enabling the system to adjust to varying conditions.

Featuring advanced control functionality, Junma’s vibration suppression and adaptive tuning functions simplify the commissioning of the machine while maintaining optimum efficiency and high-precision positioning. Junma also features other functions such as homing to marker pulse, jogging, torque limiting and electronic gearing.

Customers can select from Junma’s four different servo motor and amplifier sets, which feature rated output ranging between 100W and 750W capable of both 200V and 100V input voltages. It also offers servo motor feedback with a 16-bit incremental encoder, offering resolution of 65,536 pulses per revolution.

SEYI’s new direct drive servo presses comes in 88-440 tons

SEYI (www.seyiamerica.com) has introduced its latest range of single point and double point servo presses that were offered from 88 tons to 440 tons. Specifically designed for servo stamping applications, the new servo presses were fitted with state-of-the-art control technology and direct drive servo motor, which provides three times more torque than other servo motor available in the market today.

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.

Compact servo motors: shorter – lighter – more dynamic

The 8LV servo motor series has been expanded to include additional high-performance products. With the motto “Highest power density in the smallest installation space” in mind, all mechanical and electrical elements in this series of servo motors have been integrated into an extremely compact unit. Equipped with the smallest possible absolute encoder system with a resolution of 262144 (=218) steps per revolution, the system is able to achieve the highest precision while taking up the least amount of space.

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.

1FK7 Servo Motor Series ideal for motion control applications

The Siemens Drive Technologies Division (www.siemens.com) has released the latest 1FK7 servo motor series which has been optimized and extended for standard motion applications.

The 1FK7 series’ basic “Compact” models provide a vast array of versions and sizes that caters to all drive tasks. Its “High Dynamic” version delivers reduced rotor inertia, providing an optimum and efficient solution for tasks that require low load inertia and maximum dynamics. Offering the benefits of “High Inertia” design, Siemens delivers above-average control properties and optimum dynamics via high rotor inertia for motion control tasks that demands high load inertia. The series’ innovative design reinforces the trend toward increasingly serviceable and compact, maximum efficiency motor solutions.

With the encoder integrated with DRIVE-CLiQ interface, the 1FK7 motors now offer a low disturbing contour and a more compact package. The 1FK7 motors has also been specifically redesigned to provide a higher degree of ruggedness against shock load and vibration. Its thermal decoupling capabilities have been enhanced to achieve higher rated torques in certain versions.

Boasting maximum energy efficiency, the 1FK7 motors delivers up to 94 percent efficiency levels. To achieve the best efficiency range, project engineers can select from the series’ extensive portfolio of rated speeds that offers optimally adapted winding design. Aside from the motor’s energy savings benefits, it also offers lower system costs, thanks to the availability of smaller Sinamics converter modules and connection system.

DAANET offers compact B&R servo motors

DAANET (www.daanet.com.au) has expanded its B&R’s 8LV servo motor series portfolio to include a new range of motor-mounted gearboxes.

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.

Baum launches new generation of high torque servo motors

Customers today are looking for direct drive solutions rather than conventional motor-gearbox combinations. Thus, Baum (www.baumcycles.com) came up with a new line of DST torque motors, introduced at the Hanover Messe 2010. The synchronous motors offer a wider range of available speeds and torques, as well as a higher power density.

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.

Emsflower precision control in greenhouses by Riwo Engineering

Emsflower currently has around 26 hectares of greenhouse and grows more than 500 million plants every year. Its problem on how to minimize costs in automation system for plant handling and watering was solved by automation provider Riwo Engineering, along with the Control Techniques Drive Center.

Riwo Engineering’s new automation system had to encompass spraying and pest control, watering, autonomous function of individual sections and central control, precise positioning overruns of 250m, the transport of plants, and the means to transport water and power along 150m. This system is easy to use and all at a limited cost.

The system is composed of trolleys with plastic wheels that run on overhead rails along every 8m-wide greenhouse bay. The two wheels placed on each trolley are powered by asynchronous motors with encoders controlled by Control Techniques’ 1,5kW Unidrive SP AC drives.

The modules and trolleys, powered by Unidrive SP drives from Control Techniques, communicate through CT-Net along with the master drive and thence with the master computer. CT-Net enables several drives to be connected into a master, while the onboard programming allows the required degree of repeatability and accuracy to be reached. Its open structure, which is based on the Modbus protocol, provides the master with a low cost interface. Control Techniques’ Unidrive SP is an advanced “solutions platform” AC drive, which is configurable into five operating modes – closed and open loop, vector, regenerating and servo modes – compatible with standard networks that is configurable for all types of AC motors such as linear motors and accepts 14 position feedback protocols.

Beckhoff’s dynamic servo motors for the food industry

Beckhoff (www.beckhoff.com) has expanded its AM3000 Synchronous Servo motor series with a FDA-compliant model designed with a white surface coating – a high-performance servo solution for any applications in the food industry. The motors’ coating, which is ideal for use in any food products, is resistant to aggressive cleaning agents. Aside from the surface coating, the new servo motors are not different from the standard types from the AM3000 series.

Hygiene regulations within the food industry puts high demand on drive and control components regarding the materials and surfaces, which should be capable of withstanding regular exposure, as well as resistance against aggressive cleaners. By coating a standard servo motor so that it can be suited for use around food products, the automation provider breaks new ground: the white coating (typical in the food industry) is FDA (Food and Drug Administration) compliant and guarantees that the manufactured food products are not tainted by chemicals.

The new servo motors vary from the standard types of motors only by the surface and the stainless steel shaft. The advantage for the machine operator is that more motor types do not have to be “designed into” the machine in case of mixed use of standard and coated motors. Another advantage of the new servo motor is the price: the coating adds only around 30% to the price of the standard motors. The IP 67 design also allows use in harsh industrial environments.

Mclennan introduces new motion control range

The partnership between Allied Motion Inc. (www.alliedmotion.com) and Mclennan Servo Supplies (www.mclennan.co.uk) has been extended with the Surrey-based mechatronics specialists improving its product line coverage of the prominent European and US control manufacturer’s brushless servo motors, direct-drive torque motors, high-performance servo drives and encoders.

The close relationship between the two companies spans over 30 years with thousands of successful, small and precision, brushed and brushless motor applications for Netherlands’ Premotec B.V., which is now one of the four Allied Motion’s Technology Units. The partnership aims to develop a similar success with Allied Motion Emoteq/COPI Technology Unit and will work across the company’s own products that include X-Drive digital servo amplifiers, housed and frameless torque motors up to 2000Nm, ultra-high resolution incremental encoders and Quantum NEMA frame servo motors.

“We are very excited about working with these new Allied Motion products. We have an excellent reputation with Premotec’s small and precision DC motor range and the Emoteq/COPI products offer similar flexibility with a strong standard range and the ability to custom engineer product – even for small quantities,” said Vic Sayer, managing director of Mclennan.

Highlights of Mclennan’s new products include Megaflux range (large separate and frameless rotor/stator servo motors) up to 790mm in diameter with almost five times the speed ratings of competitive units and two times the power density. The motors are characterized by a high-pole count that maximizes rotational smoothness and torque output. The motors’ housed versions, which come with bearing system, position feedback and commutation device, target direct-drive ultra-high precision motion control in demanding automation applications like robotics, where the large through aperture may be utilized to feed services such as optics, pneumatics or electrics.

TAK Enterprises’ Dual Belt Tractor Feed uses stepper or servo motors

TAK Enterprises, Inc. (www.takenterprises.com) has unveiled a product specifically designed to feed thin strip and fine wire materials for integration or as a stand-alone unit within existing process systems. In dealing with fine wire in the 004in – 030in diameter range, pull-through feeding can be sometimes challenging. Common solutions largely involve utilizing a roll feed with custom radii ground or “V” grooves into the feed roll OD’s to match the wire diameter. However, it can also be difficult to determine the effective configuration from a cost and practical viewpoint.

The Dual Belt Tractor Feed, which is sometimes referred to as Caterpuller, is integrated with most strip processing and fine wire operations and offers benefits and features making it ideal for pull-feeding applications. The material can be guided between two pressure pads, one below and one above the cog belts. Pressure on the cog belts can be applied through an adjustable jack screw. The belts are made from plastic materials that are soft enough to flow in the wire diameter and are not very hard to avoid damage. The force is spread out across the surface area to minimize the effect when the material is being pulled, at the same time providing ample grip. Depending on the specific application, variable speed, constant speed, controllers and stepper or servo motors can be utilized to drive the Dual Belt Tractor Feed input shaft.

Absolute Multi-turn Encoders with Integrated Servo Motors from JVL

JVL Industri Elektronik’s integrated servo MAC400 and MAC800 can now be delivered with built-in absolute multi-turn encoders, with a multi-turn resolution of +/-2048 whole turns, and a single-turn resolution of either 8000 or 8192 (software-selectable) with option for higher resolutions.

Motors equipped with absolute encoders will remember their positions while powered off, thus typically eliminating a zero search operation on start up. The position is stored mechanically using toothed wheels, so there will not be any of the problems with batteries that run down, or memories that loose information, that many other systems have.

The full absolute encoder position is available at all times for use by a PLC over any of the serial or fieldbus interfaces and can be used freely in a program.

The Schneider Lexium 32 servo drive has a built-in Safe Torque Off (“STO”) function, per IEC/EN 61800-5-2, which prevents motor operation while maintaining AC input power. STO function provides faster restarts and minimize down time after incidents such as normal operator access intervention and emergency stops.

The Lexium 32 servo drives also offers an optional enhanced safety module (“eSM”) that provides additional safety interlock functions with IEC/EN 61800-5-2. This helps the user from having to clarify and engineer complex safety concepts requirements to meet international and federal regulations.

The Lexium 32 servo drives adapt to various machine needs and simplify selection by offering three servo drive models: the Lexium 32 Modular, Lexium 32 Advanced and Lexium 32 Compact. These are complemented by two motor families, the low-inertia Lexium BSH and the medium-inertia Lexium BMH. Each combination offers specific flexibility and benefits.

With nearly 550 Watts/L power density, the Lexium 32 servo drives are very compact and save the users’ control cabinet space which decreases costs and reduces the machine footprint. They also feature direct side-by-side cabinet mounting (“400% overload capacity”) and enhanced motor control features optimizing the life of the machine such as two notch filters, jerk limitation, vibration reduction and other functions.

The latest high torque extended CMP servo motors from SEW-Eurodrive

SEW-Eurodrive (www.sew-eurodrive.com) unveiled its latest servo motors with extended CMP range, the new CMP models. The freshly released servo motors with 0.5 to 45Nm torque ratings in six distinct frame sizes with 3000 rpm, 4500rpm and 6000rpm speed ratings.

The latest CMP series offers accuracy and premium dynamics in a compact-form factor. The 3-phase permanent-magnet extended CMP series servo, like the CM series, was fully assembled in Australia to ensure SEW-Eurodrive can provide a quick turnaround on complete servo motor packages.

The extended CMP servo motor series complement the existing CMP and CM servo series, and are compact, light-weight and offer high torque density. It is founded on advanced cooling fin-free aluminum housing and rare earth magnetic materials. Precision engineering assures that the CMP series servo provides positioning accuracy and premium torque to weight ratios.

The new CMP models with an option of two rotor inertias, and two brake torques, either low or high, both have a particularly low inherent mass-moment of rotor inertia.

Moreover, it has cogging levels minimized to below two percent and a 4x rated torque overload capacity. The CMP servo motor series emits lower sound levels between 55dBA and 75dBA at all speeds

The new CMP models are provided with an industry standard round canon plug connectors (both for encoder/resolver and power connections) to ensure servicing and quick on-site installation when fused with pre-manufactured cable assemblies and to increase equipment compatibility.

The CMP series has an extensive range of options. The series is provided with a standard robust resolver or fitted with an optional precision Hiperface absolute encoder.

As optional forced cooling fans, the series has a selection of high performance electro-mechanical brakes which increase the servo’s static torque. Also with an optional square flange, the units are available to allow direct machine mounting.

The CMP series plus gear unit, coupled with advanced SEW-Eurodrive’s MOVIDRIVE B application inverter, offers the complete end-to-end servo motor solution for precision positioning applications.

The new L427 Series with 5 mm air gap from Nippon Pulse

Nippon Pulse (www.nipponpulse.com) introduced its latest linear shaft servomotor from the Linear Shaft Motor (LSM) family, the L427 series. It features a five-millimeter air gap between the magnetic shaft and forcer. In the LSM family, the new L427 series offers a low-maintenance linear motion solution with applications in a broad industry range.

With a five millimeter air gap between the motors shaft and forcer, users will have more flexibility machining their device to level. Also, it is a good linear motion solution when users lack the resources or do not have the ability to make an accurate alignment of the shaft and the forcer.

The device is also an optimal motion solution for environments where there is a possibility for debris to stick to and develop on the shaft. If there is a possibility for the debris to develop on the shaft, the five millimeter air gap keeps the motor from jamming and increase the required time between cleanings.

The L427 series features a constant force of 110N and has a useable stroke length between 100 mm and 4,600 mm. The motor’s force constant is 31(Kf) N/Amps, while its peak force is 450N. Other features of the L427 include a 3-kg forcer weight, a 10 V/m/s back EMF, a 14A peak current, a 3.6A continuous current, and a 42.7 mm shaft diameter.

Nippon Pulse’s LSM has three basic concepts. The motor is high precision while giving complete stiffness with its advantageous ironless make-up that offers zero cogging. It is also simple, consisting of only one magnetic shaft and one forcer. And being non-contact, its shaft motor has a non-critical air gap that eliminates force variation throughout the entire stroke of the device.

Seamless Motor Identification from B&R

B&R Industrial Automation has announced the latest enhancement to its family of servo, synchronous, and torque motors: the embedded parameter chip. This integrated chip stores pertinent mechanical and electronic motor data such as serial number, type, parameters, and manufacturer specifications making the entire power transmission system clearly identifiable in the application program.

The drive reads the motor data from the encoder. With this data the encoder automatically determines the current control paramaters to guarantee optimal control of the motor. This substantially reduces the time and resources required for manual entry of motor data during commissioning; it also eleminates any margin for error.

Another advantage of the embedded parameter chip is that it supports automatic system configuration. Machine builders and end users can seamlessly field swap motors of varying performance without adjusting their program file or drive configuration.

Simplified diagnostics

The embedded chip acts as a thumbprint for motor parameters so they may be identifed and confirmed. When troubleshooting a drive system, the ability to promptly verify the accuracy of motor parameters allows users to quickly eliminate the motor as the issue and focus their diagnostic efforts elsewhere. The end result is efficient diagnostics and reduced downtime.
