Stepper motors are a subject that keeps recurring. This little circuit changes a clock signal (from a square wave generator) into signals with a 90-degree phase difference, which are required to drive ...

A motor-generator system mainly performs motor control to provide motive power and also controls regeneration by the motor acting as a generator. Advances aimed at lower fuel consumption and reduced ...

In a powertrain fitted with eTorque, a belt-driven motor-generator unit replaces the conventional alternator on the engine. This motor-generator unit performs several functions in addition to the ...

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 ...

The Genecon motor/generator is a motor or hand cranked DC generator that is used to drive another Genecon motor/generator and/or to light a series of LEDs. The Genecon motor/generators are fragile.

[Robert Murray-Smith] doesn’t like the price of inverters to convert DC to AC. That led him to build a dynamotor, or what is sometimes called a motor-generator set. These devices are just DC motors ...
