The fixed cover 204; the internal heat dissipation air duct assembly 300 includes an internal heat dissipation fan blade 301 fixedly installed at the rear of the rotating shaft 105, a second guide ring 302 fixedly installed at the inner rear end of the high-voltage motor body 100, a front fixed cover 303 movably installed at the front end of the high-voltage motor body 100, a third guide ring 304 fixedly installed inside the front fixed cover 303, an external air intake filter 205 fixedly installed on the outer rear end of the rear fixed cover 204, and the external air intake filter 205 has a circular structure, an external air outlet 206 is reserved at the front end of the rear fixed cover 204, an internal air outlet 305 is reserved at the inner end of the front fixed cover 303, and an internal air intake filter 306 is fixedly installed on the inner rear end of the rear fixed cover 204, and the internal air intake filter 306 has a circular structure.

[0024] Specifically, a high-voltage motor refers to an electric motor with a rated voltage of 1000V or higher. Commonly used voltage levels are 6000V and 10000V. A high-voltage motor is a device that converts electrical energy into mechanical energy. The external cooling fan blades 202 installed on the outer rear end of the inner shaft 105 of the high-voltage motor body 100 draw cooling air in through the external air intake filter 205 and deliver it along the first guide ring 203 and the outlet air vent 206 to the cooling fins 103 at the outer end of the high-voltage motor body 100, thereby dissipating external heat from the cooling fins 103 at the outer end of the high-voltage motor body 100. Meanwhile, the internal cooling fan blades 301 at the outer rear end of the shaft 105 draw cooling air in through the internal air intake filter 306 and deliver it along the high-voltage... The second guide ring 302 at the inner end of the motor body 100 delivers cooling air to the space between the stator 101 and the rotor 102. After removing the heat between the stator 101 and the rotor 102, the air is output to the outer end of the high-voltage motor body 100 along the guidance of the third guide ring 304 at the front end of the high-voltage motor body 100 and the inner air outlet 305. This is to dissipate heat between the stator 101 and the rotor 102 at the inner end of the high-voltage motor body 100. In turn, the heat dissipation effect of the inner and outer ends of the high-voltage motor body 100 is improved through the heat dissipation channels at the inner and outer ends of the high-voltage motor body 100. The fixing rods 201, which are fixedly connected to the shaft 105 on both sides of the inner end of the outer heat dissipation fan blades 202, are mainly to avoid affecting the air intake of the inner heat dissipation fan blades 301.

[0025] Working principle and usage process of this utility model:

[0026] During operation of the high-voltage motor body 100, the rotor 102 and shaft 105 in its internal stator 101 will rotate. The rotation of the shaft 105 will also drive the outer cooling fan blades 202 and inner cooling fan blades 301 at its rear end to rotate synchronously. As the outer cooling fan blades 202 rotate, they filter the incoming cooling air through the outer air intake filter 205, and then transport the incoming cooling air through the first guide ring 203 to the outlet air vent 206. After exiting the outlet air vent 206, the air is delivered to the outer end of the cooling fins 103, thereby activating the cooling effect of the high-voltage motor body 100. The outer heat dissipation fins 103 provide uniform heat dissipation. As the inner heat dissipation fan blades 301 rotate, they filter the external cooling air drawn in through the inner air intake filter 306. The drawn-in cooling air is then guided by the second guide ring 302 and transported between the stator 101 and the rotor 102. After removing the heat between the stator 101 and the rotor 102, the air is then output to the outer end of the high-voltage motor body 100 along the third guide ring 304 at the front end of the high-voltage motor body 100 and the inner air outlet 305. This achieves synchronous and uniform heat dissipation between the inner and outer ends of the high-voltage motor body 100 during use.
