Discover how to build a simple electromagnetic motor and generator using everyday materials in this hands-on science ...

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 ...

Stepper motors are great for a bunch of projects; CNC machines, clocks or robots for example. Sometimes when working on a project that does include a stepper motor and driver, it would be nice to test ...

Christine and Scott Gable are hybrid auto and alternative fuel experts who have brewed their own biodiesel and traveled 125,000 miles on waste vegetable oil. Electric vehicles rely exclusively on ...

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 ...

Any stepper motor can be used as a generator. In contrast to other generators, a stepper motor produces a large induced voltage even at low rotational speeds. The type used here, with a DC resistance ...
