A Textbook of Electrical Technology - Volume II

A new chapter entitled Special Machines has been added to this volume for the first time. It deals with various types of Stepper Motors, Permanent-Magnet DC Motors, Printed-Circuit DC Motors, PM Synchronous Motors, Resolvers and Servomotors both DC and AC. Stepper motors are widely used for operation control in computer peripherals, textile industry, IC fabrication and robotics. They are also used for applications requiring incremental motion. PM synchronous motors are used where precise speed must be maintained to ensure consistent product. The switched-reluctance motor is still in its infancy but has been successfully applied to a wide range of applications both industrial and domestic.
