Abstract: This article proposes a new method to optimize the efficiency of a 7.5 kW induction motor connected to a synchronous generator. The Synchronous generator is a part of an emergency power ...
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 ...
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, ...
Abstract: This paper summarizes some design challenges encountered in the development of a high speed induction motor/generator for a plug-in hybrid electric vehicle (PHEV). The traction system ...
Today, most electric machines operate with radial flux (RF). Magnax offers a new concept, though—a machine that operates with axial flux (AF). Figure 1 provides a comparison of the RF and AF ...
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 ...
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 ...

The USS Gerald R. Ford’s Electromagnetic Catapults Could Be Great—If They Worked
It was well past time for the US Navy to replace its aging steam catapults with electromagnetic ones—but the new EMALS system has seen significant challenges of its own.
