What’s New in Motor Technologies
There are two major motor technology driving forces in two different segments of motion control. The first involves power efficiency and the second is torque density. Power efficiency improvements are driven by the DOE. A recent development using sheet metal stators and multiple dimension Halbach magnet arrays has significantly increased the power efficiency levels in motors below 50 horsepower (34.3 Kw) used in various speed applications.

Efficient Operation of Stepping Motors
Stepping motors are highly popular because they offer high torque at low speed, and high precision at low cost. These unique benefits enable the design of direct drive systems, eliminating the additional cost and complexity of gearboxes. However, stepping motors are not known for being energy efficient and, because if overloaded they tend to stall and lose step awareness, they are usually over-designed for the application with a safety margin of at least 50 percent. This presentation will discuss two new techniques that overcome these challenges.

Driving Circles Around Linear Motion
Through the convergence of two well known drive principles, rotary and linear motion, new linear transport designs are now possible that result in game-changing advantages for machine builders and manufacturers. These benefits include reduced wiring, network and software platforms that are shared with the overall machine automation system and a significantly reduced machine footprint. This has led to the advent of higher performance mechatronic solutions for numerous applications including product packaging with variable product flow, complex material handling lines and many more.

Illustrations for a Dynamic Braking Chopper Solution in A Medium Voltage AFD
As an induction machine’s rotor is accelerated to a desired process speed the electromagnetic torque is positive. Therefore, real power is supplied to the machine and it operates in the ‘motoring’ mode. However, when the rotor is slowed, yet still positive in speed, the difference in load and inertia can result in negative electromagnetic torque. This ‘generating’ mode machine power can be absorbed in adjustable frequency drives using a dynamic braking chopper. Learn how the chopper is sized for a full speed ramp stop.

A Look at Soft Magnetic Composites for Motor Design
The benefits of soft magnetic composites (SMCs) have been promoted for several years but the have been slow to enter many application areas. Recent advances in SMC technology may change this and open many opportunities for designers to improve the power density and efficiency of motor designs through the use of SMC instead of conventional motor laminations. This presentation will share some observations using specific examples where the performance of SMCs can be directly compared to the performance of conventional laminated motor designs.

Improving Reliability of Inverter Driven Motors with Shaft Voltage Testing and Bearing Protection
The bearings in AC motors operating on variable frequency drives (VFD) are vulnerable to shaft voltages that may be of sufficient amplitude to cause electrical discharges in the motors bearings. These discharges produce an electrical discharge machining (EDM) effect in the motor’s bearings that cause pitting and fluting and premature bearing failure. The shaft voltages may be detected and measured using an oscilloscope and a shaft voltage probe that touches the motor’s shaft while it is running.

Amorphous iron is the most efficient magnetic material available for motors, especially at design frequencies exceeding 400 Hz. Five demonstration motors have been built; two of these motors are in test with more than 10,000 hours. The motor’s advantages over conventional approaches is to create higher efficiency motors wasting less energy, air cooled designs where competing motors are liquid cooled, and due to the lower heat loss, compact designs result in overall less material usage.
