Embodiment Construction

[0026] The present invention will be further described through the embodiments below in conjunction with the accompanying drawings.

[0027] Such as Figure 1 to Figure 4 As shown, the cooling system of the present invention and the disc motor with the cooling system can obtain a disc motor with a compact structure, good cooling effect, and no obvious increase in processing difficulty without increasing the axial length of the motor. .

[0028] In this embodiment, a double-stator single-rotor amorphous alloy disc motor is used for illustration, but it is not limited thereto. Other silicon steel disc motors can also adopt the cooling method of the present invention.

[0029] The disc motor includes a casing 6, a motor front end cover 21 and a motor rear end cover 22, and a rotor disk 3, a winding 4 and a stator 5 are installed in a cavity formed by the casing 6, the motor front end cover 21 and the motor rear end cover 22. , specifically, the double-stator single-rotor amorph...

Abstract

The invention relates to a cooling system and a disc type motor with the same, and belongs to the technical field of motors. The cooling system comprises a cooling channel inlet, a cooling channel outlet and a cooling channel communicating the cooling channel inlet and the cooling channel outlet, wherein the cooling channel is located on a stator, the stator is provided with a cooling channel placement groove, the stator is also provided with a dovetail groove for accommodating and fixing a dovetail groove wedge of the stator, and the dovetail groove wedge is provided with a cooling channel opening at a position corresponding to the cooling channel placement groove. On the premise that the axial length of the motor is not increased, the cooling system has the advantages of being compact instructure and good in cooling effect, and the machining difficulty is not obviously increased.

Description

technical field [0001] The invention relates to a cooling system and a disc motor with the cooling system, which belongs to the technical field of motors, and is especially suitable for a disc motor whose stator is connected with an end cover through a dovetail groove. Background technique [0002] The structure of the first motor invented by Faraday in 1831 was a disc motor. However, the manufacturing and installation process of the stator and rotor of this type of motor is complex, and the axial magnetic pull between the stator and rotor is relatively large, which results in a large axial load on the bearing, increased mechanical loss, and low efficiency. Thus, when the traditional radial flux (cylindrical) motor was introduced in 1837, the disc motor fell into the cold shoulder. For more than a hundred years, conventional radial flux motors have dominated. [0003] With the development of modern industry, there is a demand for miniaturization and flattening of motors, a...
