Description

Technical Field

[0001] The invention relates to the technical field of disc motors, and in particular to a single-disc double-stator disc motor structure for mining. Background Art

[0002] With the development of modern industry, there is a demand for miniaturization and flattening of motors. Flat disc motors have regained attention and more and more research has been done on this type of motor. Compared with traditional radial flux motors, disc motors have the characteristics of short axial size and high power density. They are usually used in special applications with limited axial space, such as mines.

[0003] The invention patent with announcement number CN111682679B discloses a dual-rotor single-stator disc motor, which uses a housing boss and a positioning plate to fix the stator. It has a simple structure and is easy to process, solving the problem of difficult mechanical installation of the stator and housing of the dual-rotor single-stator amorphous alloy permanent magnet slotted disc motor; in addition, the housing boss integrated with the housing and the fixing measures of the positioning plate can effectively prevent the stator from axial movement; in addition, the cooling channel adopts a built-in method, which has a stronger heat dissipation capacity compared with the end cover cooling or the housing external cooling method.
