Engineers select system components to minimize total cost, yet ensure that the motor is protected from the damaging effects of heat, power distortion, and harmonics. This piece from Engineering360 reviews how PM motors operate; examines why some engineers are shifting from induction to PM motors; and explains the role filters play in optimizing PM motor performance.     View now   TMB+ New Torque Motors Family ETEL S.A.

View now   Linear Positioners with Nanometer Precision Thanks to the precision afforded by a piezo motor, interferometric linear encoder, and stepping drive, these new nanometer-precision linear positioners provide peak performance in precise applications such as microscopy and semiconductor testing. Select travel ranges of 0.5, 1, and 3 in. Incremental motion is less than 1 nm, encoder resolution is 0.5 nm.   Learn more   Clean Power, Few Harmonics Designed for high-voltage applications, this small yet powerful drive can operate at up to 13.8 kW with a power capacity of 40 MW in a single thread. It employs a relatively small filter (for a reduced footprint) and generates fewer harmonics than comparable drives. Applications include offshore operations, energy extraction, and power generation.
