Abstract

Rapid advancements in industry and the demand for control systems have widely brought the use of servo systems in great attention. Hence, investigation of various servo motors and their industrial applications is significant. Today, servo systems are often used to control the speed, position and torque in machine tools and robots. Servo motors are capable of performing the control commands, with high accuracy and speed. High acceleration, power factor, stability, durability, thermal and other environmental robustness along with their ability of controlling the torque in a wide range of speeds leads the practical engineer towards the choice of servo motors for control purposes in industry. In this paper, servo systems are reviewed at first. Then, selection of different DC and AC motors for achieving the desired specifications in servo systems is discussed with the aid of well-known selection criteria such as efficiency, robustness, torque per unit current, ripple torques, cost, etc. It is concluded that for precise control of position and speed along with high dynamic performance, the Permanent Magnet Synchronous Motor (PMSM) would be the best choice.
