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 ...

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.

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 ...

An introduction to the symmetric, multiphase, wound-rotor “synchronous” doubly-fed motor or generator system, called SYNCHRO-SYM. How SYNCHRO-SYM is only possible with brushless, automatic, ...

Figure 8 depicts an electrical vehicle climbing an incline moving forward (top) or in reverse (bottom). When the vehicle rolls downhill it will turn the motor pressed by the force of gravity so the ...

Horse Powertrain wasn't the only automotive supplier showing an efficiently packaged range-extender engine system at this year's IAA Mobility Munich show, which wrapped up over the weekend. German ...

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 ...

[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 ...
