Changing the orientation of rotor magnets on the fly lets a special kind of induction motor run directly from ac lines. The quest for energy efficient electric motors has generated a lot of ...

Brushless doubly-fed induction generators (BDFIGs) represent an innovative class of electric machines that eliminate the need for mechanical brushes, thereby increasing reliability and reducing ...

A dc motor driving an ac alternator was used to simulate an asynchronous wind electric generator. The output was used to drive a commercial air conditioning unit containing a hermetically sealed three ...

Since the boom of the NdFeB magnets industry, the usage and potential applications for permanent magnet machines have grown exponentially to the detriment of traditional induction systems. In special ...

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, ...

While GM’s announcement of a new car based on the Camaro platform being shown at the Chicago Auto Show stole the spotlight in the automotive press, the Buick Regal eAssist represents a product far ...

On the eve of the 2011 Chicago Auto Show, Buick has just unveiled the Regal eAsssit powered by the same mild-hybrid powerplant as the recently-announced Buick LaCrosse eAssist. Combining the 115V ...

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 ...
