Electric Motors and Drives: Fundamentals, Types and Applications
Even though annealed at the mill, fully processed material may require further stress relief anneal after stamping. The stresses introduced during punching degrade the material properties around the edges of the lamination, and must be removed to obtain maximum performance. Because of its lower electrical conductivity, aluminum wire requires a 1. Insulation Modern magnet wire typically uses one to four layers of polymer film insulation, often of two different compositions, to provide a tough, continuous insulating layer. It uses a symbolic language on engineering drawings and computer-generated three-dimensional solid models that explicitly describes nominal geometry and its allowable variation.

By Austin Hughes and Bill Drury. Electric Motors and Drives: Fundamentals, Types and Applications, Fifth Edition is intended primarily for non-specialist users or students of electric motors and drives, but many researchers and specialist industrialists have also acknowledged its value in providing a clear understanding of the fundamentals. It bridges the gap between specialist textbooks too analytical for the average user and handbooks full of detail but with little insight providing an understanding of how each motor and drive system works. The fifth edition has been completely revised, updated and expanded.

Book DescriptionElectric Motors and Drives is intended for non specialist users of electric motors and drives,filling the gap between maths and theory based academic textbooks and the more prosaic'handbooks', which provide useful detail but little opportunity for the development of real insightand understanding. The book explores all of the widely used modern types of motor and drive,including conventional and brushless D. The third edition includesadditional diagrams and worked examples throughout. New topics include digital interfacing andcontrol of drives, direct torque control of induction motors and current fed operation in DC drives.

An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft. Electric motors can be powered by direct current DC sources, such as from batteries, or rectifiers , or by alternating current AC sources, such as a power grid, inverters or electrical generators. An electric generator is mechanically identical to an electric motor, but operates with a reversed flow of power, converting mechanical energy into electrical energy. Electric motors may be classified by considerations such as power source type, internal construction, application and type of motion output. In addition to AC versus DC types, motors may be brushed or brushless , may be of various phase see single-phase , two-phase , or three-phase , and may be either air-cooled or liquid-cooled.
