Detailed Description

For the sake of understanding, the present invention will be further described with reference to the accompanying drawings.

Referring to fig. 1, for the embodiment of the utility model provides a section schematic diagram of disc motor, the utility model provides a disc motor is middle rotor double stator structure, including rotor 4, preceding stator subassembly and back stator module, wherein, preceding stator subassembly includes front end housing 11, preceding stator core 21, preceding heat pipe 31 and front winding 71, and back stator module includes rear end housing 12, back stator core 22, back heat pipe 32 and back winding 72, and rotor 4 passes through bearing 5 and installs in the casing that front end housing 11 and rear end housing 12 are constituteed, has air gap 6 between rotor 4 and the stator core.

The structural principle of the front stator assembly and the rear stator assembly are the same, and only the front stator assembly is taken as an example for detailed description, as shown in fig. 2, the front stator core 21 is contained in the front end cover 11, the front winding 71 is located in the slot of the front stator core 21, meanwhile, the slot is also provided with the front heat pipe 31, the front heat pipe 31 and the front winding 71 are attached to each other, and two ends of the front heat pipe 31 are fixedly connected with the front end cover 11 through the outer ring mounting bolt 81 and the inner ring mounting bolt 82 respectively. The heat absorbing section of the front heat pipe 31 is closely attached to the front winding 71, and the heat dissipating section of the front heat pipe 31 is closely attached to the front end cover 11. As can be seen from fig. 2, in order to improve the heat dissipation efficiency, the front heat pipes 31 are disposed in one-to-one correspondence with the winding grooves of the front stator core 21.

During the operation of the motor, the front winding 71 and the rear winding 72 generate a large amount of heat, and the heat can be conducted to the front end cover 11 and the rear end cover 12 through the front heat pipe 31 and the rear heat pipe 32, and finally emitted to the surrounding environment, so as to reduce the temperature thereof. Therefore, the utility model provides an among the disc motor, the heat that produces in the time of stator module's winding operation can in time be sparse, is favorable to reducing disc motor's operating temperature, prolongs its life.

It should be understood that the stator assembly in the above embodiments can be applied to disc motors of other structures besides disc motors of a middle rotor and double stator structure, and the heat dissipation principle is the same, and the heat pipes in the wire embedding grooves are used for conducting the heat of the windings to the end covers and finally dissipating the heat to the surrounding environment.
