Servo motor is a rotary motion that allows for precise control of angular or linear position, velocity, and acceleration. It consists of a suitable motor coupled to a sensor for position feedback. Servo Motor is a synchronous motor (Permanent Magnet Motor). Torque remains constant up to a rated speed of the motor. It has been used in high position accuracy & constant torque required applications.
As the technology of microprocessor unit becomes more advanced and much further, the development and cost effectivity of permanent magnet manufacturing technology for servo motor and high power and high performance semiconductor power devices is improved continuously. Therefore, AC servo motor and AC servo control systems have become the basic techniques for accomplishing automation control technology in the current industry field.
Servo motors are used in applications such as robotics, CNC machinery, or automated manufacturing.
