What is a servo motor?

After the industrial revolution, mechanical equipment was widely used in all walks of life. We usually see all kinds of large and small household appliances, but there is one thing that is important but not well known. It is——servo motor.

Servo motor, or “servo” refers to the engine that controls the operation of mechanical components in the servo system. It is an indirect transmission device that assists the motor.

Although servo motors are compact, they are very powerful and are known to be incredibly energy-efficient. Servo motors are used in home appliances, cars and industrial equipment.

Servo motors can control speed and position accuracy very accurately, and can convert voltage signals into torque and rotational speed to drive control objects. The rotor speed of the servo motor is controlled by the input signal and can respond quickly. In the automatic control system, it is used as an actuator and has the characteristics of small electromechanical time constant, high linearity, starting voltage, etc. It can convert the received electrical signal Converted into angular displacement or angular velocity output on the motor shaft. They are divided into two categories: DC and AC servo motors. Their main feature is that there is no rotation when the signal voltage is zero, and the rotational speed decreases at a constant speed as the torque increases.

All in all, servos can rotate and push parts of a machine with precision by its electronic devices and actuators, and is widely used by manufacturing companies.
