MOTOR BUILT-IN WHEEL, EQUIPPED WITH COOLING CHANNELS, AND COOLING JACKET Russian patent published in 2021 - IPC B60K7/00 H02K5/20 H02K9/19 

FIELD: motor-wheels.

SUBSTANCE: motor built-in a wheel for a vehicle contains a stator and a pipeline for supplying a refrigerant. Channels for cooling electromagnets of the stator are extended along a stator case and connected to the pipeline. Cooling channels have an inlet and an outlet. Electromagnets are placed around the stator case. Channels are divided into three groups, while channels in each group are connected in parallel, and they determine the direction of flow for the refrigerant, so that, for each channel in the group, the refrigerant flows in the same direction along the circumference of the stator case from the first end to the second end of the channel. One of groups contains two or more channels, while groups are connected in series. Each of annular cooling channels is formed as an annular section extended for 180 degrees or more and less than 360 degrees around a longitudinal axis of the stator case.

EFFECT: cooling is improved.
