[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 ...

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 ...

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 ...

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 ...

Plug-in electric vehicles for passengers continue to become more mainstream within the automotive market, and the shift in that direction shows no signs of slowing down. In fact, Bloomberg New Energy ...

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 ...

“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 ...

Opera software for motor and generator design lets users define complex behaviors such as friction, load, and speed-dependent torques. April 24, 2008 Multiphysics capabilities show the effects of ...

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 ...
