Abstract

The invention relates to a wheel hub motor stator support with a low water resistance cooling structure and a wheel hub motor. The stator support comprises a pipe wall and an end face which are perpendicular to each other and are fixedly arranged, an upper half circumference flow channel and a lower half circumference flow channel are symmetrically arranged in the pipe wall, and a water inlet and a water outlet are symmetrically arranged on the end face. The water inlet end of the upper half-cycle flow channel and the water inlet end of the lower half-cycle flow channel are both communicated with the water inlet through a first axial flow channel, and the water outlet end of the upper half-cycle flow channel and the water outlet end of the lower half-cycle flow channel are both communicated with the water outlet through a second axial flow channel; each of the upper half-cycle flow channel and the lower half-cycle flow channel comprises a plurality of U-shaped flow channels which are arranged in parallel, each U-shaped flow channel is arranged along the axial direction of the stator support, the plurality of U-shaped flow channels are circumferentially and uniformly arranged on the pipe wall of the stator support, and the adjacent U-shaped flow channels are communicated end to end. The hub motor stator support water cooling structure is small in water resistance and good in heat dissipation effect.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a hub motor stator support and a hub motor with a low water resistance cooling structure. Background technique [0002] The hub motor integrates the power, transmission and braking devices into the hub, so the mechanical part of the electric vehicle is greatly simplified. This driving method can shorten the power transmission path and cancel the entire power transmission system, thereby improving the performance of the vehicle. transmission efficiency. [0003] In the low-speed external rotor hub motor, the installation space of the motor is very limited. The inner stator assembly is composed of an armature assembly and a stator support. The armature assembly includes a stator core, an insulating frame, a stator coil and a slot wedge. It is used to support the stator core, and on the other hand contains a water channel cooling structure for cooling the motor. [0004] Due to the...
