Wing Motor Split Motor Design from Wittenstein

Bartlett, Ill. – Wittenstein’s swing servo motor, also known as the wing motor because of it’s appearance, is the newest innovative mounting concept in motor mounting, originally created as a customized solution. 

The hollow-shaft direct drive wing motor has two swinging stator halves that feature a mounting concept for unique integration and operating scenarios where axial installation and removal in or from a machine are not possible. The split stator contains two parallel, three-phase systems which allow for the stator to be joined together in a controlled way. Each stator half contains a water-cooling pipe system made from stainless steel. It prevents damage to the drive due to intense heat stemming from the roll. It can be retrofitted or dismantled at any time for maintenance, and is designed to withstand the harshest of operating environments.

This motor operates the same way as a classic, one-piece direct drive with impressive performance.

New Price Reduction on V Series AC Motors from Oriental Motor

Torrance, Cal. – Oriental Motor announces a new, lower price on its high-strength V-Series AC motors. These high-strength motors use a special tooth-surface machining technology combined with an optimized quiet-running design that maintains the motor’s strength. High-accuracy assembly technology ensures precision at micro levels. 

Maximum permissible torque is increased by up to two times the level of conventional AC motor gearheads. If the load condition changes, the gearhead’s strength can easily accommodate it and there is no need to increase the size of the motor or gearhead. Specific torque is dependent on frame size.

The motor’s strength is due to its rigid case, a proprietary side-panel construction and an optimized gear design. The larger diameter bearing serves to extend its useful life.

Stepper motors

One of the most common motors used in motion control applications is the stepper motor. These motors are used mostly in positioning applications and have the advantage of being able to be very accurately controlled for the most precise positioning applications, down to fractions of a degree without the use of feedback devices such as encoders or resolvers. They are operated in open-loop (not closed-loop), without the need for tuning parameters as in closed-loop servo systems.

Steppers are generally classified by the number of allowable steps they can be commanded to move. For instance, a 1.8 degree step motor is capable of 200 steps/revolution (1.8 x 200 = 360 degrees, or one full revolution) in full-step mode. If operated in half-step mode, each step becomes 0.9 degrees and the motor can then turn 400 steps/revolution. Another mode called microstepping subdivides the degrees per step even further, allowing for extremely precise movements.

There are several different stepper motor technologies including permanent magnet motors, variable reluctance, and hybrid types. The principle of operation for stepper motors is fairly straightforward. Traditional variable reluctance stepper motors have a large number of electromagnets arranged around a central gear-shaped piece of iron. When any individual electromagnet is energized, the geared iron tooth closest to that electromagnet will align with it. This makes them slightly offset from the next electromagnet so when it is turned on and the other switched off, the gear moves slightly to realign. This continues with the energizing and de-energizing of individual electromagnets, thus creating the individual steps of motion.

Hybrid stepper motors are more expensive than permanent magnet stepper motors but provide better performance with respect to step resolution, torque and speed. Hybrid steppers combine the best features of both the permanent magnet and variable reluctance type stepper motors. The rotor is multi-toothed like the variable reluctance motor and contains an axially magnetized concentric magnet around its shaft. The teeth on the rotor provide a path to help guide the magnetic flux to preferred locations in the airgap. This further increases the detent, holding and dynamic torque characteristics of the motor when compared with both the variable reluctance and permanent magnet motor.

Stepper motors are relatively inexpensive and can be run open loop, requiring no feedback devices. Also, because the speed is proportional to the frequency of the input pulses, a wide range of speeds is attainable. However, while stepper motors are capable of producing high torque at low speeds, they generally are well suited for lower power applications not for applications requiring lots of torque to move heavier loads. They are best for applications requiring the control of rotation angle, speed, and position.

A few drawbacks are that not properly controlling the motor can produce undesired resonance in the system. Also, stepper motors are generally not easy to operate at extremely high speeds. And as the motor speed increases, torque decreases.

For two-phase stepper motors, there are two basic kinds of winding structures; unipolor and bipolar. A unipolar arrangement uses 6 wires but current can only flow in one direction. These types of motors also require a unipolar driver. A bipolar winding uses 4 wires and current can flow in 2 directions and it requires a bipolar drive. Bipolar motors are generally more efficient and can provide more torque than unipolar models, although they can heat up faster than unipolar motors.

A stepper motor’s low-speed torque varies directly with current. How quickly the torque falls off at higher speeds depends on a number of factors such as the winding inductance and drive circuitry including the drive voltage. Steppers are generally sized according to torque curves, which are typically specified by the manufacturer.

Nippon Pulse Linear Shaft Motor Features Sub-Micron Resolutions

Radford, Va. – The Nippon Pulse Linear Shaft Motor is designed and constructed for ultra high-precision applications needing sub-micron resolutions. Because of its design features, the Linear Shaft Motor is more energy efficient and can achieve motion profiles that similar linear motors can’t.

The design of the Linear Shaft Motor maximizes use of magnetic flux, provides stiffness up to 100-times greater than that of other ironless linear motors, minimizes generated heat and reduces the impact of heat on the work point. It also doesn’t produce Eddy currents, and doesn’t have cogging issues. As a result, the Linear Shaft Motor can achieve sub-micron motion profiles, outperforming competing linear motors.

The Linear Shaft Motor’s cylindrical design provides two inherent benefits. First, the motor is able to use 100 percent of magnetic flux and to use that magnetic flux at maximum efficiency. All available magnetic flux cuts the coils at a 90-degree angle.

Also because of its cylindrical design, and despite being completely ironless, the Linear Shaft Motor provides stiffness up to 100-times greater than all other similar motors.

In part because it has no cogging issues and does not produce Eddy currents, the Linear Shaft Motor also generates less heat than traditional linear motors. As a result, the motor does not dump heat into the work point and thus is able to achieve precise and accurate motion profiles. The lower heat production also comes because the Linear Shaft Motor does not have inherent airflow restrictions.

In tests conducted by the University of Virginia, the Linear Shaft Motor is proven to consume 51.8 percent less energy than a comparable u-shaped motor while performing the same motion, carrying the same load, and producing the same linear force.

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.

New Linear Motor Line from Siemens

Elk Grove Village, Ill. – With the recent introduction of its 1FN6 Linear Motors, Siemens now offers three models of Linear Motors for seamless integration with all Sinumerik or Simotion control systems using Sinamics drives. The three new motors are the 1FN3 Peak Load Motor, 1FN3 Continuous Load Motor, and the1FN6 Magnet Free Secondary.

The 1FN3 Peak Load Motors feature high acceleration/deceleration and velocity rates and can be used for horizontal or compensated vertical axes.  They feature nominal force of 8,100 N, maximum force of 20,700 N, and maximum velocity of 253 m/min with liquid cooling.

The 1FN3 Continuous Load Motors feature long power-on duration for horizontal, inclined or compensated vertical axes. Nominal force is 10,375 N, maximum force is 17,610 N with maximum velocity of 129 m/min with liquid cooling. Both the 1FN3 Peak and Continuous load motors can be run with air convection cooling, but the ratings must be reduced by 50%.

Lastly, 1FN6 Magnet Free Secondary motors are ideal for long traverse lengths at high acceleration and velocity rates and can be used for horizontal, inclined or compensated vertical axes. The nominal force is 2,110 N with maximum force of 8,080 N and a maximum velocity 532 m/min  with air convection cooling.

One linear motor stationary track (either with magnets or magnet-free) can support multiple primary sections moving either the same slide in a master-slave configuration or moving separate slides independently at different rates and in different directions.  This allows designers to consolidate drive systems on multiple slide machines for cost efficiency and better productivity. Also, linear scales for position and velocity feedback are available from a variety of third party suppliers to suit the application.

To help in the design and application process, Siemens has developed a number of tools to help take a slide design application and configure the right size motor to it. Once this process is complete, it is a simple matter to integrate the motor(s) into a complete Siemens system that includes controls, motors, operator stations and even complete panels and cabinets.

Demystifying Permanent-Magnet Machines

The book Design of Brushless Permanent-Magnet Machines by J.R. Hendershot and T.J.E. Miller is fully revised and expanded from the first edition that the authors published back in 1994.

“Engineering is a practical art with just enough theory,” the authors say. In what a lot of designers consider the dark art that is electric machine design, the authors manage to shed much light.

The authors bring a wealth of not only theoretical knowledge but practical design experience to the new edition which serves to ground the book in the day-to-day world of the practicing design engineer.

Who will benefit from the book? First and foremost, those engineers who are designing the motors and controllers themselves. But the book also benefits the systems integrators and designers who are putting together motion control systems because it is a great in-depth guide for anyone interested in the inner workings of brushless permanent-magnet (PM) machines. The emphasis is on motors, but there is a chapter devoted to generators as well.

One of the most innovative features of the book is the chapter devoted to k_T and k_E, the so-called figures of merit. These two constants point out the fundamental relationship in any electric machine between the current and torque and between speed and EMF. The authors look squarely at the fact that different manufacturers use different conventions and definitions for these parameters and attempt to bring some clarity to the situation.

There is also a useful chapter on losses and cooling and a chapter that treats both square wave and sine wave drives. The back sections of the book include an extensive list of symbols and abbreviations, as well as an appendix with FAQ about machine design.

With the Internet and the Web as one of, if not the primary, source of information for busy designers these days, it can sometimes feel that a lot of information is scattered all around the Web and it takes considerable effort and Googling to find what you’re looking for. Here, everything you need to know about PM machine design is in one physical book. The extensive bibliography contains over 300 references, many of which, as the authors point out, are simply not available on the Internet, residing in books and archival journals published before 1980.

In my undergraduate days and during my first co-op work experience, I found a book at my employer that served me well for getting to the heart of a technical matter like no classroom textbook could. The Art of Electronics by Horowitz and Hill was an indispensable bible of electronic circuit knowledge. This book has something of that spirit in that it is comprehensive and practical, although it does unquestionably contain more mathematics, as motor design, by its very nature, demands it, and takes care to mention and discuss the practical considerations of machine design.

All in all, the book is quite an achievement and a welcome addition to the designer’s reference shelf.

The kit is ordered based on the NEMA “u” shaft diameter and depending on the shape of the motor’s end bracket, it provides the correct size ring for the motor and four styles of lock washers and brackets with bolts, which can be used in configurations.

Useful for motor repair shops, HVAC service contractors, original equipment manufacturers and plant maintenance departments, the ring prevents electrical “fluting” damage in the bearing, expensive motor repairs or replacements, bearing noise and downtime by safely directing VFD-induced bearing currents to ground. To make installation of the ring on NEMA frame motors easy, the brackets in the U-Kit can be mounted on the motor either by using AEGIS Conductive Epoxy or by drilling and tapping small holes.

The ring’s conductive microfibers are integrated securely in the AEGIS FiberLock channel and surrounding completely the motor shaft to provide discharge points to dangerous shaft currents. The design creates the path of minimal resistance, which redirects these currents effectively away from bearings to ground. The microfibers are designed for flexibility to prevent breakage.

BEI Kimco Solves High-Speed Motor Application

Vista, Cal. – BEI Kimco Magnetics, a company of Custom Sensors & Technologies (CST), Inc., recently developed a BLDC motor to meet the challenging high-speed requirements for a turbomolecular vacuum pump application. The turbomolecular pump is used in the semiconductor device manufacturing process, which requires highly compressed gases for chemical deposition and implantation. The pump design incorporates the specially designed BEI motor driven turbine rotor, which is capable of operating speeds of up to 70,000 rpm.  The extremely high speeds are essential to achieve vacuum pressures down to one micropascal.

Key to the success of the project was to design a compact, reliable and efficient motor capable of reaching and maintaining the required speeds under continuous duty conditions. To meet the customer’s specifications, BEI Kimco developed a frameless permanent magnet BLDC motor measuring 1.4” in diameter x 1.4” in axial length. The rotor/stator part set configuration allows the motor rotor to be directly coupled to the load, resulting in excellent operating efficiencies, minimal parts count and a compact form factor. A stainless steel sleeve secures the magnets in place at the extreme speeds.

With its exceptionally high-speed capabilities, the new motor can be adapted to a wide variety of other applications including medical hand-pieces and pumps.  Pricing is from $100.00 in production quantities with delivery in eight weeks.

For further information contact BEI Kimco Magnetics at (760) 597-7042, or toll-free at (800) 572-7560, or via Fax: (760) 597-6320; email: sales@beikimco.com;  www.beikimco.com

NovaTorque Introduces 2 and 3 HP Premium Plus+ Motors

Sunnyvale, Cal. – NovaTorque, Inc. has released the 2 and 3 HP @ 1800 RPM motors of the company’s line of Premium Plus+ high efficiency electric motors.  These motors offer higher efficiency and smaller size at a price competitive to current NEMA Premium induction motors.  The motors are available direct from NovaTorque either as a motor system paired with a variable frequency drive (VFD) or standalone.

The 2 HP Premium Plus+ motor has a full-load rated efficiency of 91.5% at the rating point of 1800 rpm, while the 3 HP Premium Plus+ motor has a full-load rated efficiency of 90.5%.  In comparison, the full-load NEMA Premium motor ratings are 86.5% and 89.5% for 2 and 3 HP motors respectively.  In addition to having higher efficiency at the rating point than NEMA Premium motors, the Premium Plus+ motors maintain their high efficiency over a much wider speed and load range.  The net result is a 5-to-8% average improvement in operating efficiency over that of a NEMA Premium motor in a typical variable speed, variable load application such as a fan or blower.  The improvement is even more dramatic when compared to typical installed induction motors, averaging in the range of 15 to 30%.

The Premium Plus+ motors are also smaller than comparable NEMA Premium motors. The benefit to equipment manufacturers is the ability to reduce the size of the motor cabinet or enclosure, or use a direct-drive configuration in fan applications, saving cost of materials. The 2 HP Premium Plus+ motor is available in a 143T frame, while the 3 HP version is available in a 143T or 182T configuration. Foot and flange mountings are also available.

The Premium Plus+ motors are based on NovaTorque’s unique stator and rotor hub geometry. The laminated field poles used in the stator have conical end-surfaces, instead of the conventional perpendicular flat cross-section. The rotor hubs have conical shapes that match the end-surfaces of the field poles. This approach doubles the surface area available for magnetic flux transmission, while minimizing the volume of materials. The increased surface area at the rotor/stator interface concentrates the magnetic flux. This allows NovaTorque to use lower cost ferrite magnets in its interior permanent magnet (IPM) rotor hubs to achieve motor efficiency and performance that equals or exceeds much more expensive motors that use rare-earth (neodymium) magnets.

Sample units of the Premium Plus+ motors are available to qualified OEMs and systems integrators. For information and to obtain a sample, contact NovaTorque at 1-888-516-8776, or email sales@novatorque.com.

Initial sizes in the 2.5 and 4.5 in. diameter are offered. Future sizes are planned.

These motors remain true to the ULT ultra-thin origins with low-profile construction. ULT motors operate using standard three phase brushless DC or brushless AC drivers with voltage ranges from 12-300V with Hall device options also available.

There is no need to only go slow with Applimotion ULT motors. Direct Drive doesn’t necessarily mean low speed. Speeds of up to 10,000 rpm can now be achieved with the correct electrical match between the motor and driver.

Miniature Piezomotor Linear Slide

Auburn, MA – Physik Instrumente’s (PI) patented P-653 piezomotor linear slide is significantly smaller than other miniature linear stages and provides significantly higher velocities and resolution. It features a travel range of 2mm with force generation to 0.15N and comes pre-assembled and mounted on a PC board and is only 8mm long.

This true linear motor system has no conversion of rotation, eliminating rotary conversion losses, and consists of only 4 parts and can replace classical drive elements like miniaturized motor/lead screw systems or other linear motors with speeds of up to 200mm/sec (8in./sec) and an auto-locking feature. Integration of the P-653 is simple because the moving slider and the piezomotor are delivered assembled as a unit on a PCB driver board running on 5VDC.

P-653-series PILine® ultrasonic motors are ideal for OEM applications where quantities are high and space is at a premium. The systems are optimized for moving small objects such as optical fibers, micro-optics, or micro-electromechanical elements fast and precisely. These non-magnetic ceramic motors can also be used in medical applications.

Motion is controlled by TTL voltage pulses applied to the driver electronics. The self-adjusting driver creates the high-frequency, nanometer level oscillations (~500kHz) that make the ultrasonic ceramic motor move. PILine^® linear piezomotors are based on a patented ultrasonic drive. At the heart of the system is a rectangular monolithic piezoceramic plate (the stator), segmented on one side by two electrodes. Depending on the desired direction of motion, the left or right electrode of the piezoceramic plate is excited to produce high-frequency eigenmode oscillations of hundreds of kilohertz. PILine® motors are vacuum compatible, non-magnetic and self-locking.

QuickStep Motors from JVL

JVL has now launched its newest product: ‘QuickStep’ — the integrated step motor. QuickStep will be available in 2 models. The first to reach the market is a model with pulse and direction inputs. The second model will have a position controller with a serial interface, 8 IO´s, and an optional encoder and CANbus interface.

In the past decade, pulse/direction interfaces have become increasingly popular for the control of step and servo motors. This is due to the fact that pulse/direction signals provide a simple and reliable interface which is 100% digital, precise, and offers immediate response. When a pulse is sent, the motor instantaneously moves 1 step forward. For example, if the motor has a resolution of 200 steps/revolution, it will move 1.8 degrees. By changing the frequency of the applied pulse signal, it is possible to accelerate the motor. By counting the number of pulses, the motor’s position can be determined without any error whatsoever. The direction input is used to determine the motor’s direction of rotation.

All the required electronics are integrated in the motor itself in a single compact unit. The motor can be supplied with the connector either on the back or side of the housing. Either a M12 connector, screw terminal or DSUB connector can be supplied. The QuickStep motors, cables and planetary gears can be supplied from stock.
