Title:
STATOR ASSEMBLY AND MOTOR
Document Type and Number:
WIPO Patent Application WO/2023/088328
Kind Code:
A1
Abstract:
The present application relates to the technical field of motors, and in particular, to a stator assembly and a motor. The stator assembly comprises a stator core and a winding; the stator core is provided with multiple stator slots, the stator slots being sequentially arranged along a circumferential direction of the stator core, forming an annular array; the winding is embedded in the stator slots, the winding being wound using rectangular conductors; multiple layers of rectangular conductors can be mounted in each stator slot, and rectangular conductors in each layer are sequentially arranged along a radial direction of the stator core. An average cross sectional area of rectangular conductors close to a center of the stator core is greater than an average cross sectional area of all the rectangular conductors in the stator slot, thereby reducing a loss density thereof and balancing heat generation and heat dissipation of different conductors in the stator slot, so as to achieve the purpose of improving heat dissipation performance of the motor by means of reducing a maximum temperature of the motor.
