Huawei authorized its stator components, motors and electric vehicles patent

According to the company’s search app, on March 30, Huawei Technologies Co., Ltd. was authorized to disclose patent information on “stator components, motors and electric vehicles”, with the publication number CN212850004U. The patent summary of Qichao showed that: this application discloses a stator assembly, a motor and an electric vehicle. The stator assembly includes stator core and windings.

The stator core includes an outer wall and an inner wall opposite each other. The inner wall is provided with a plurality of stator slots, which are arranged at intervals along the circumferential direction of the stator core; along the radial direction of the stator core, each stator slot is equally divided into multiple slot layers; among them, every three adjacent stator slots are used as a stator slot group.

The windings include three-phase windings, and the three-phase windings are sequentially and alternately wound in different stator slot groups along the circumferential direction of the stator core. Each phase winding includes three branches connected in parallel, and the three branches are rotationally symmetrical around the axial direction of the stator core. Based on the stator assembly, the three branches of the in-phase winding can be in a state of potential balance, so as to avoid the circulation phenomenon between the branches of the in-phase winding as much as possible.
