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 ...

The AC induction motor is often referred to as the workhorse of the industry because it offers users simple, rugged construction, easy maintenance, and cost-effective pricing. These factors have ...

To meet the demand for drive motors / generators needed for hybrid vehicles, engineers at Remy International Inc. designed a line of off-the-shelf devices that are said to have the highest ...

From tiny hysteresis motors that drive electric clocks to huge synchronous motors that develop more than 50,000 hp, the alternating current (AC) motor has become an indispensable part of everyday life ...

The topic of motors and motor control techniques is wide and varied. Part one of this two-part article will cover the principles of alternating-current (AC) motor operation and control. Part two will ...

Continuing headlines about superefficient electric drives might lead some observers to wonder about the future of three-phase induction motors. The truth is that induction motors aren’t going away any ...

The increasing importance of energy efficiency has brought electric motor makers to promote a variety of schemes that improve motor performance. Unfortunately the terminology associated with motor ...

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.

AC induction motors are everywhere, from ceiling fans to vehicles. They’re reliable, simple, and rugged — but there are some disadvantages. It’s difficult to control the speed without complex ...
