AC Servo System
AC servo system includes AC servo systems based on asynchronous motor and AC servo systems synchronous motor based on induction motor.
1800 battery’ invention is the beginning of electrical motor, the birth and development of motor can be divided into several stages after that. . From the 20th century until the 1970s is growth and maturity period of motor, there are brush DC motors, induction motors, synchronous motors, stepper motors and other motors have been born. Then the introduced of the semiconductor-driven technology and the concept of electronic control have bringing the practical of frequency driven.
From the 1970s to the late 20th century, the rapid development of computing technology brings opportunity for high-performance drive systems. With advancement of the design, evaluation, measurement, control, power semiconductors, bearings, magnetic materials, insulating materials and the manufacture technology, Motor body experienced lightweight, compact, high efficiency, high torque output, low noise and vibration, high reliability, low cost and a series of changes, and the corresponding drive and control devices are also more intelligent and procedures.
