Description

Technical Field

[0001] The utility model relates to the technical field of servo motors, in particular to a low-noise and high-performance servo motor. Background Art

[0002] A servo motor is an engine that controls the operation of mechanical components in a servo system. It is an auxiliary motor indirect speed change device. The servo motor can control the speed and position accuracy very accurately. It can convert the voltage signal into torque and speed to drive the control object. 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 and high linearity. It can convert the received electrical signal into angular displacement or angular velocity output on the motor shaft. It is divided into two categories: DC and AC servo motors. Its main characteristics are that there is no self-rotation when the signal voltage is zero, and the speed decreases uniformly with the increase of torque.

If it is in a hot state for a long time, the energy consumption of the servo motor itself will increase, and it will easily become stuck, which will greatly reduce the efficiency of subsequent work and greatly shorten the life of the servo motor.
