Title:
STATOR ASSEMBLY AND FLAT WIRE ELECTRIC MOTOR HAVING MULTIPLE WIRES ARRANGED IN SAME SLOT LAYER
Document Type and Number:
WIPO Patent Application WO/2023/109885
Kind Code:
A1
Abstract:
The present application relates to the technical field of flat wire electric motors, and particularly to a stator assembly and flat wire electric motor having multiple wires arranged in the same slot layer. The stator assembly comprises a stator core and a stator winding, wherein the stator core is substantially cylindrical; a plurality of stator slots are provided in the stator core; and a plurality of combined conductor layer groups are arranged in each stator slot. Compared with the prior art, the stator assembly provided in the present application can allow the length-width ratio of each rectangular conductor to be reduced, while ensuring that the total sectional areas of conductors in the stator slots are similar, so that U-shaped wire forming is facilitated, and the manufacturability of same is better. In addition, the length and width of each rectangular conductor in the stator slots and the shape of the stator slot are adjusted, and the radial distance of the stator slot, the inner diameter of a stator, and a stator yoke portion are adjusted by means of a stator toothing, so that the flux density distribution of each part of the stator assembly is reasonable, the slot filling rate is improved, and the working efficiency of the electric motor is improved.
