The technical scheme adopted by the invention is: a permanent magnet DC motor for food processing machine, which comprises a stator component, a rotor component and an aluminum alloy front end cover gear box. The aluminum alloy front end cover gear box is an integrated fixed connection, which comprises a front end cover equipped with a ball bearing and matched with the front end of the transmission shaft of the rotor component, and a gear box perpendicular to the side of the front end cover The stator assembly is provided with a symmetrical carbon brush plate accessory, the rear end of the stator assembly is provided with a rear end cover of the stator, the bottom of the rear end cover of the stator is provided with a black wire buckle, the other end of the wire buckle is connected with a red black lead, and the tail of the red black lead is connected with a terminal box socket; the rear end cover of the stator is provided with an aluminum alloy rear end cover wind vane cover, and the aluminum alloy rear end cover wind vane cover is provided with a ball bearing 2、 The tail end of the transmission shaft of the rotor assembly is connected with the air vane through the ball bearing 2, and the rear end of the air vane is provided with the air vane cover plate matched with the air vane cover of the aluminum alloy rear end cover.
Further, one side of the air vane cover of the aluminum alloy rear end cover is provided with a flat air outlet, and the air vane is pressed to the same level with the cover plate of the air vane cover.
Further, the front end of the front end cover is respectively provided with an oil cover of plastic material, a bearing felt containing sponge and a cylindrical oil-bearing.
Further, the gearbox body is provided with a plastic gear meshed with the rotor transmission shaft, the outer side of the gearbox body is provided with a gearbox cover, and the center of the gearbox cover is provided with a circular oil seal.
Further, the gear box cover is provided with four symmetrical anti-skid screw mounting holes, and the four mounting positions are guaranteed to be in the same plane.
Furthermore, the red black lead surface is provided with a PVC black sleeve with a thickness of 0.5mm and a temperature resistance of 125 ℃.
In conclusion, the permanent magnet DC motor for the food processor of the invention can ensure the stability of the motor when it works as a whole through the integrated aluminum alloy front end cover gear box design and equipped with a fan blade heat dissipation device. At the same time, it has the characteristics of high output efficiency, low noise and fast heat dissipation.
