Title:
STATOR, STATOR ASSEMBLY, AND RESOLVER
Document Type and Number:
WIPO Patent Application WO/2024/016217
Kind Code:
A1
Abstract:
A stator, a stator assembly, and a resolver, beneficial to reducing the interference of a shaft current in a motor on a resolver signal. The stator comprises a yoke part and a tooth part located on one side of the yoke part. The tooth part comprises a plurality of teeth or slots; the plurality of teeth or slots are used for arranging a stator winding; and the stator winding comprises a first phase winding. The yoke part is provided with at least two recesses; the at least two recesses comprise a first recess and a second recess; and the first recess and the second recess are symmetrical about a first axis of symmetry, wherein the first axis of symmetry is a straight line passing through the center of the stator and forming, with a first straight line, an included angle smaller than or equal to a first angle, and the first straight line is a straight line passing through the center of the stator and a center point of a first tooth or a first slot, wherein the first tooth or the first slot is used for arranging the peak number of turns of the first phase winding.
