The two most important electric motors are the ac induction motor and the permanent magnet (PM) brushless synchronous motor, also known as the brushless dc or ac servo motor. These motors have ...

Synchronous motors have a stationary magnetic field relative to the rotor. Permanent magnets or field windings through slip rings create the field. Induction motors have a rotating magnetic field ...

This document written by Steve Bowling, Application Segments Engineer at Microchip Technology, discusses how motor works and describes the AC induction motor, variable-speed ACIM control, and FOC.

Motors have been central to automation since the beginnings of the first industrial revolution in the mid 18th century and their varied forms and applicability maintain their centrality into the 21st ...

What consumes more than half of the world's electricity and supports nearly every facet of industrial production? The answer is the AC induction motor. Although these motors typically tolerate ...
