Title:
MOTOR STATOR, MOTOR AND METHOD FOR INSTALLING STATOR WINDING
Document Type and Number:
WIPO Patent Application WO/2021/047172
Kind Code:
A1
Abstract:
Disclosed are a motor stator, a motor and a method for installing a stator winding. The motor stator comprises a stator core and a stator winding. The stator core comprises stator core teeth and a stator core yoke. The stator core teeth are distributed in the circumferential direction of the stator core yoke, and stator slots for bearing the stator winding are formed among the stator core teeth. The stator core teeth comprise parallel teeth and non-parallel teeth. The parallel teeth and the non-parallel teeth are arranged at intervals. Two opposite tooth surfaces of the adjacent parallel teeth and non-parallel teeth are parallel to each other. According to the motor stator, the parallel teeth and the non-parallel teeth are arranged at intervals, and the formed stator slots are all parallel slots, the gaps among coils in the stator slots are reduced, the slot fullness rate is increased, and the thermal resistance in the stator is reduced, so that the power density of the motor is improved, the stator winding coils are convenient to install, and the assembly difficulty of the coils is reduced.
