Discover why impulse voltage insulation class (IVIC) is critical when selecting IEC motors for converter duty.

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 ...

Once the control method of choice only in high-performance industrial ac-servo drives, FOC (field-oriented control) is finding its way into lower end industrial and many appliance applications with ...

The two windings are out of phase by 45 to 90 degrees which gives the motor a boost on startup. Unlike the capacitor-start-induction-run motor that used a capacitor, this motor makes use of a ...

DC machines can be classified as self-excited, separately excited, permanent magnet (PM), and brushless. Self-excited machines can be further classified as shunt, series, and compound. Compound ...

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.

Today’s sophisticated ac drives offer ease-of-use, higher performance, more features, smaller size, and lower cost-per-function than ever before. Most recently, the insulation systems within ac motors ...

One of the more elusive causes of three-phase compressor motor overheating and failure is an imbalance in voltage. Compressor voltage unbalance can be found with a voltmeter by measuring between ...

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 To meet the demand for drive motors / ...
