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

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 ...

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 ...

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 ...

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.

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 ...

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 / ...

Nidec Traction has launched a high-capacity auto-winding AC motor production line at its Mexico plant, marking a significant step in the company’s global growth strategy. The new line, capable of ...
