Embodiment 1

[0037] Such as Figure 1-2 As shown, this embodiment proposes a disc-type double-air-gap outer rotor coreless motor. In this embodiment, the motor is an in-wheel motor as an example for illustration, and the motor includes an inner stator assembly and an outer rotor assembly. The so-called outer rotor means that the motor shaft of the inner stator assembly is in a fixed position, the entire inner stator assembly is in a fixed position, the housing of the outer rotor assembly is rotatable, and the entire outer rotor assembly is rotatable.

[0038] The outer rotor assembly includes a housing 101 , at least one pair of disc yokes 102 inside the housing 101 and several permanent magnets 103 mounted on opposite surfaces of the pair of disc yokes. This embodiment includes four disc yokes 102 located in the housing 101, two adjacent disc yokes 102 form a pair, and four disc yokes 102 form three pairs, each pair of disc yokes 102 Several permanent magnets 103 are installed on the opp...

Embodiment 2

[0062] Such as image 3 , 9 As shown in -11, this embodiment proposes a disc-type single-air-gap outer-rotor ironless motor, which includes an inner stator assembly and an outer rotor assembly.

[0063] The outer rotor assembly includes a housing 101 , at least one disc yoke 102 inside the housing 101 and several permanent magnets 103 installed on the disc yoke. This embodiment includes a disk-shaped yoke 102 located in the housing 101, a number of permanent magnets 103 are installed on the opposite surfaces of the disk-shaped yoke 102 and the ironless coil 202, and the permanent magnets on the yoke 102 The magnetic poles of 103 are the same in the same radial direction, that is, both are N poles or S poles in the same radial direction, and N poles and S poles are alternately distributed in the same circumferential direction.

[0064] The inner stator assembly includes a motor shaft 201 and disc-shaped ironless coils 202 located on the motor shaft 201 , the number of the dis...

Embodiment 3

[0084] Such as Figure 13-17 As shown, the difference between this embodiment and Embodiment 1 is that the motor of this embodiment includes two yokes 102 and two ironless coils 202, one yoke 102 and one ironless coil 202 form a group, each Each yoke 102 is provided with a permanent magnet 103 opposite to the ironless coil 202 .

[0085] The cooler 4 of this embodiment is set on the outer wall of the motor shaft 201, and the heat of the vacuum superconducting module is directly transferred to the cooler 4, which is more conducive to the heat dissipation of the vacuum superconducting module.

[0086] The motor shaft 201 has a hollow cavity 2011, the motor shaft 201 is provided with a through hole, the water inlet pipe 61 and the water outlet pipe 62 connected with the water flow channel are connected on the cooler 4, and the water inlet pipe 61 and the water outlet pipe 62 pass through the through hole and then go from the hollow out of cavity 2011.

[0087] The coreless coil...

Abstract

The invention relates to a disc-type outer rotor coreless motor, which includes an outer rotor assembly and an inner stator assembly. The outer rotor assembly includes a casing, a disk-shaped yoke located in the casing, and several permanent magnets installed on the disk-shaped yoke ;The inner stator assembly includes the motor shaft and the disc-shaped ironless coil located on the motor shaft, the disc-shaped ironless coil is opposite to the permanent magnet; the motor includes a vacuum superconducting module, and the vacuum superconducting module is in contact with the disc-shaped ironless coil , used to dissipate the heat generated by the disc-shaped ironless coil. The heat generated by the ironless coil can be rapidly cooled, and the heat dissipation efficiency is high. The heat dissipation method of the present invention can meet the heat dissipation requirement of the ironless coil.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a disc-type outer rotor ironless motor. Background technique [0002] With the increasing scarcity of energy around the world, more and more attention has been paid to the effective use of energy. Generators and motors are the top priority in the development of contemporary energy equipment, and energy conservation and environmental protection are key issues that need to be solved urgently. Asynchronous motors and excitation synchronous motors are the most common motors at present. They all have double iron loss and copper loss. The actual efficiency is only 60-70%, and the energy consumption is relatively high. The permanent magnet synchronous motor is slightly better in efficiency and energy saving than the previous two motors, but it is still not ideal. It has double losses of copper loss and iron loss, and a large permanent magnet reluctance. On the surface, it seems that the ...
