Problems solved by technology
However, the traditional stator yokeless modular axial flux permanent magnet motor has a compact structure and high power density, and the huge loss generated by the compact space can easily lead to excessive temperature rise of the winding and damage the winding insulation. Therefore, how to improve the stator core And winding heat dissipation capacity has become a problem to be solved urgently by those skilled in the art
The motor cooling system used in the prior art usually makes the coolant only contact with the winding, which often leads to poor cooling effect of the stator core

The invention discloses a stator water cooling structure of a stator yoke-free axial magnetic flux permanent magnet motor, which aims to improve the heat dissipation capability of a stator core and a winding, and comprises the stator core, a water cooling device, an armature winding and a shell. According to the stator magnet-yoke-free modular axial magnetic flux permanent magnet motor cooling structure, the cooling water channel is arranged between the motor stator core and the winding, so that the cooling liquid can be in contact with the stator core and the winding at the same time, the contact area is large, the heat dissipation capacity of the stator core and the winding is improved to a great extent, and the service life of the motor is prolonged. The uniformity of temperature distribution of the stator core and the winding is obviously improved, and the heat dissipation capability of the motor is greatly improved.
Description
technical field [0001] The invention relates to the technical field of permanent magnet motors, in particular to a stator water cooling structure of an axial flux permanent magnet motor without a yoke. Background technique [0002] The stator yokeless axial flux motor is a kind of permanent magnet motor, which has the advantages of small size, high power density and high efficiency. However, the traditional stator yokeless modular axial flux permanent magnet motor has a compact structure and high power density, and the huge loss generated by the compact space can easily lead to excessive temperature rise of the winding and damage the winding insulation. Therefore, how to improve the stator core And the cooling capacity of the winding has become an urgent problem to be solved by those skilled in the art. The motor cooling system adopted in the prior art usually makes the cooling liquid only contact with the winding, which often leads to poor cooling effect of the stator core...
