[0002] Servo motor refers to the engine that controls the operation of mechanical elements in the 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;

[0003] The existing servo motor will generate a certain amount of heat when in use. The general servo motor does not have a heat dissipation structure. When the servo motor is used for a long time, the large amount of heat generated can easily cause the servo motor to malfunction. Therefore, we have introduced a new cooling device for the servo motor. Utility Model Content
