AC servo motor is a synonym for the electric motor used on an AC current source, which is effective for the constant or indefinite position, speed, acceleration and several other factors.
AC servo motors offer superior performance in terms of speed, torque, and precision. They are suitable for high-performance applications requiring precise control. DC servo motors, while not as precise, are easier to control and maintain, making them suitable for less demanding applications.
Servo motors typically have a lifespan ranging between 20,000 and 30,000 operating hours under standard conditions
AC servo motors are used in applications that require high precision, speed, and torque control, such as in robotics, CNC machines, and automated manufacturing systems. They are also found in packaging and printing machinery, medical equipment, and other industrial equipment that needs dynamic and accurate motion.
