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 ...

The truth is that induction motors aren’t going ... mandating higher efficiency standards for general-purpose, three-phase ac industrial motors from 1 to 500 hp manufactured for domestic use.

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 ...
