What is a servo motor?
A servo motor, also called an actuator motor, is an actuator in an automatic control system that converts the received electrical signal into an angular velocity output or an angular displacement output on the motor shaft.
Since the introduction of servo motors, servo motors have proven to be quite useful in many industries. For many years, servo motors have been involved in completing large tasks. They may be small in size, but they are very powerful and energy efficient. With these features, servo motors are widely used in remote control toy cars, airplanes, robots and various industrial equipment. In recent years, servo motors have also been used in industrial applications, online manufacturing plants, pharmaceutical services, robotics and food service industries.
How many types of servo motors are there?
There are two types of DC servo motor and AC servo motor. The main feature is that there is no rotation when the signal voltage is zero; the rotation speed decreases uniformly with the increase of torque.
DC servo motors are ideal for small applications but cannot handle high current surges. However, AC servo motors can handle higher current surges and are widely used in industrial machinery. When it comes to price, DC motors are cheaper than AC servos, so they are used more. In addition, DC motors are specifically designed for continuous rotation, making them ideal for robotic motion.
