Title:
FLAT WIRE ELECTRIC MOTOR AND STATOR THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/026824
Kind Code:
A1
Abstract:
Provided in the embodiments of the present application are a flat wire electric motor and a stator thereof. The stator comprises a stator iron core, and a stator winding arranged on the stator iron core. An inner wall of the stator iron core is provided with a plurality of winding grooves, which are arranged in a circumferential direction of the inner wall of the stator iron core. The stator winding comprises a plurality of coil units, each of which comprises a first coil and a second coil, wherein the first coil comprises a first insertion portion, a second insertion portion, and a first connection portion that connects the first insertion portion to the second insertion portion; the second coil comprises a third insertion portion, a fourth insertion portion, and a second connection portion that connects the third insertion portion to the fourth insertion portion; the first insertion portion, the third insertion portion, the fourth insertion portion and the second insertion portion are arranged in a circumferential direction and are respectively inserted into different winding grooves; the first insertion portion is connected to the fourth insertion portion; and the second connection portion is located on the side of the first connection portion facing the stator iron core. According to the embodiments of the present application, a wire embedding process can be simplified, and the height of the end of the stator winding can be reduced.
