[0019] The working principle of the utility model is as follows: when the utility model is used, first, the operator needs to connect the driver body 2 to the servo motor and other equipment through the power input port 17, ensure that the power supply voltage is consistent with the requirements of the driver body 2, and pay attention to the polarity not to be connected incorrectly. The operator holds the lifting handle 22 to lift the driver body 2 and insert the driver placement slider 14 into the driver placement slot 13, so that the driver body 2 is placed inside the protective outer box 1, which not only realizes the convenient installation and movement of the driver body 2, but also improves the operability and portability of the driver body 2, and also reduces the risk of damage during transportation. , open the second power switch protective shell 21 installed on the surface of the lower left side of the front end of the protective outer box 1, turn on the main switch 18, the main switch 18 is used to control the power on and off of the driver body 2.

According to the function and application scenario of the driver body 2, open the first display adjustment protective shell 19, configure its parameters through the display screen 15 and the adjustment button 16, the driver body 2 receives the AC power from the external power supply through the power input port 17 to provide power for the entire driver body 2, and the AC power enters the driver body After the driver body 2, it is first converted into direct current by a rectifier circuit to provide a stable direct current power supply for subsequent circuits; then, the feedback circuit board 23 is used to collect the status information of the servo motor, such as rotor position, speed, current, etc. The transmission port 24 is used to connect the driver body 2 and the feedback circuit board 23. The transmission port 24 usually has a high bandwidth and anti-interference ability to ensure the accuracy and real-time performance of signal transmission. The relay 25 plays an isolation role between the driver body 2 and the control circuit 23. The relay 25 receives the control signal of the driver body 2 and controls the operation of the servo motor of the external device; however, the driver body 2 is at high speed. A large amount of heat will be generated during operation. If the heat dissipation is not good, it may cause the performance of the device to decline or be damaged. Therefore, the operator needs to turn on the heat dissipation motor 9 by adjusting the button 16. The heat dissipation motor 9 drives the rotating shaft 10 to rotate, and the rotating shaft 10 drives the heat dissipation blades 11 to rotate, thereby transferring the cold air on the heat dissipation box 5 to the driver body 2, and exchanging the hot and cold air through the ventilation filter holes 3. The heat dissipation blade limiter 12 is used to limit the rotation range of the heat dissipation blade 11 to prevent the heat dissipation blade 11 from being damaged, thereby achieving effective heat dissipation of the driver body 2, improving the working efficiency and service life of the driver body 2, and also reducing maintenance costs.
