[0024] In order to solve the problem of easy overload of the motor when the yaw speed reducer is running, the driving motor 2 can be installed on the top end of the motor seat body 1 by screws when the yaw speed reducer needs to be operated. When the driving motor 2 drives the output shaft to rotate, the torque limiter 5 will work. When the load is in a normal state, the steel ball in the torque limiter 5 is engaged with the pit, and under the cooperation of the driving shaft and the connecting sleeve 6, the sun gear 8 rotates, so that the speed reducer can operate normally. When overload occurs, the steel ball in the torque limiter 5 will move away from the pit, causing the driving end component (speed reducer) and the driven end component (motor output shaft) to slip, thereby avoiding damage to the driving motor 2 or the speed reducer parts caused by overload. The torque limiter 5 is made of stainless steel, which effectively improves the durability of use. The first sensor 15 can be used to transmit the slip information of the torque limiter 5. When the torque limiter 5 slips, the pressure plate arranged above it will move up by 2mm, entering the sensing range of the first sensor 15. After receiving the signal, the first sensor 15 outputs the slip information through a group of transmission lines 16. The staff should cut off the power supply in time. The second sensor 17 can be used to detect and transmit the speed information of the driving motor 2. The lower end surface of the second sensor 17 is 5mm away from the sealing sleeve 4. An M3 hexagonal head bolt (bolt head thickness 2mm) is installed on the sealing sleeve 4. When the bolt is rotated to the position below the sensor 2, the speed information is output once. The sealing sleeve 4 is 1mm lower than the pressure plate above the torque limiter 5, which can avoid the influence of the bolt signal on the sensor 1, thereby facilitating timely reminding the staff of the status of the torque limiter 5.

[0025] With reference to Figure 3 , one side of the inner wall of the motor seat body 1 is fixedly connected with a check ring 9, the bottom of the check ring 9 is fixedly connected with an oil seal 10, and the oil seal 10 is arranged on one side of the torque limiter 5.
