Electric Motors (2nd Edition) (Book with DVD)

An electric motor is a device for converting electrical power into mechanical power. An electric motor will try to deliver the required power even at the risk of self-destruction. In certain applications, such as in the transportation industry with traction motors, electric motors can operate in both motoring and generating or braking modes to also produce electrical energy from mechanical energy. Found in applications as diverse as industrial fans, blowers and pumps, machine tools, household appliances, power tools, and disk drives, electric motors can be powered by direct current (DC) sources, such as from batteries, motor vehicles or rectifiers, or by alternating current (AC) sources, such as from the power grid, inverters or generators. Small motors may be found in electric watches. General-purpose motors with highly standardized dimensions and characteristics provide convenient mechanical power for industrial use. The largest of electric motors are used for ship propulsion, pipeline compression and pumped-storage applications with ratings reaching 100 megawatts.

This book ‘Electric Motors’ provides engineers with drive techniques that will help them develop motor drive system for their applications. This second edition serves as the most authoritative and reliable guide to electric motor utilization and assessment in the commercial and industrial applications.
