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 ...

Small and medium AC induction motors account for more than 75% of motor electrical energy demand; however, they typically receive less maintenance than their larger counterparts. This leaves them ...

AC motors are abundant in the HVAC industry. Every fan and pump application requires an AC motor. For efficient and reliable control, adjustable-speed drives are becoming a common companion for these ...

A good digital multimeter (DMM) is key to diagnosing compressor problems in general. For instance, in a previous article (May 15 issue of The NEWS) we discussed using the DMM to read suction and ...

Blind calculation of horsepower for positioning motors can yield values that seem nonsensical to the uninitiated. It's common to see manufacturers of ac motors publish horsepower ratings for their ...

Any electrical motor, from an idealized viewpoint, consists of two sets of magnets—one set stationary, one set free to move—placed in special geometric relation to one another. For most practical ...

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.
