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 ...

“Our dealers, as a routine matter, ask the type of questions [shown] to ensure the generator meets the application requirements,” says John Garcia, Doosan Portable Power. “The supplier’s goal is to ...

The National Electrical Manufacturers Association (NEMA) recently published 2018 updates to ANSI/NEMA MG 1 Motors and Generators. NEMA’s flagship Standard, MG 1 assists users in the proper selection ...

Rosslyn, Va.-based Electrical Manufacturers Association (NEMA) has published NEMA MG 1-2009, Revision 1-2010, "Motors and Generators." The standard is produced by NEMA’s Motor & Generator Technical ...

Engineering efforts to simulate radial-flux machines concentrate on inherently 2D problems. Most of the 2D FEA software is good for "quick-and-easy" solutions demanded by shorter design schedules.

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 ...
