In this revised and expanded edition, Howard E. Jordan explains-in a clear manner-the technology of energy efficient electric motors including motor losses, testing, and efficiency labeling. He also discusses how to calculate the return on investment for an energy efficient motor in addition to several other subjects related to effective motor applications. New chapters explore permanent magnet synchronous motors and transistor pulse-width-modulated inverters. Engineers, purchasing managers, and executives who make decisions on motor selection will find this an invaluable reference.The electronic switching circuit is an integral part of the aquot;brushless dcaquot; idea and serves the function of keeping the ... The vast majority of brushless dc motors in service today have a three-phase ac stator winding and permanent magnets on the rotor. ... The circuit diagram corresponding to this figure showing the power switching circuit for the brushless dc control and the synchronous motor is given in Fig.
