Tesla Motors CEO Martin Eberhard is an electrical engineer, so he's qualified to describe the 284-horsepower 3-phase, 4-pole AC induction motor that will power the revolutionary Tesla Roadster.

The two basic types of AC motors are induction and synchronous motors. AC motors can operate on single-phase or three-phase power. In general, AC motors require little maintenance. Depending on its ...

In module 1 you will learn principles of operation of AC induction motors, both single and 3-phase types. You well then learn how to interpret data from torque speed curves, and how to optimize data ...

Industry generally runs on three-phase AC systems, mainly because three-phase electric motors are so much more efficient and compact than the equivalent single-phase motor. But residential ...
