Double-rotor single-stator disc type motor

Abstract

The invention relates to a double-rotor single-stator disc type motor, which belongs to the technical field of motors. The double-rotor single-stator disc type motor comprises a casing, a front end cover and a rear end cover, and a winding and a stator iron core located in the casing, the front end cover and the rear end cover. A casing boss is arranged at the position, corresponding to the statoriron core, of the inner side of the casing, the casing boss and the casing are of an integrated structure, positioning pressing plates are installed on the two sides of the stator iron core, and cooling channels are arranged between the casing boss and the front end cover and between the casing boss and the rear end cover. The double-rotor single-stator disc type motor has the advantage that theproblems of stator fixation and motor cooling can be solved.

Description

technical field [0001] The invention relates to a double-rotor single-stator disk motor, which belongs to the technical field of motors, and is especially suitable for a double-rotor single-stator amorphous alloy slotted disk motor. 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 complicated, and the axial magnetic force between the stator and rotor is relatively large, which makes the axial load of the bearing larger and the mechanical loss increases. , the efficiency is low. 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, the conventional radial flux motor has dominated. [0003] With the development of modern industry, there is a demand for miniaturization and flattening of motors, and flat disc motors ...

AI Technical Summary

Problems solved by technology

This method has the advantages of compact structure, simple process and installation. However, in order to provide cooling channels on the end cover of the disc motor and ensure the mechanical strength of the end cover of the motor, it is inevitable to increase the thickness of the end cover of the motor.

[0009] In summary, the existing disc motors mainly have the following deficiencies in the fixing and cooling methods: 1. The fixing method is difficult to ensure the radial position accuracy of the stator, and it is easy to damage the winding insulation; 2. The cooling system has a complex structure and requires high processing technology , it is more difficult to realize; 3. The installation of the cooling system will increase the axial size of the disc motor, which is not conducive to the improvement of the power density of the motor
