Title:
STATOR STRUCTURE, MOTOR, AND ELECTRICAL EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2023/097912
Kind Code:
A1
Abstract:
A stator structure (100), a motor, and electrical equipment. The stator structure comprises: a stator core (110) comprising a stator yoke (112) and a plurality of stator teeth (114), the plurality of stator teeth being arranged on the stator yoke, a stator slot (120) being formed between adjacent stator teeth, each stator tooth comprising a tooth body (116) and a tooth boot (118), the tooth body being arranged on the stator yoke, and the tooth boot being arranged on the tooth body; and a winding (130) arranged on the stator teeth, the winding comprising flat wires (132) wound on the stator teeth in a concentrated manner, the flat wires being wound on the stator teeth in multiple layers, and the number of flat wires in the layer of the winding away from the stator teeth being not more than the number of flat wires in the layer of the winding close to the stator teeth, wherein the width of the side of the tooth body close to the tooth boot is 2×t1, the width of the side of the tooth body close to the stator yoke is 2×t2, and 1.5×t1≥t2≥t1. The use of a concentrated winding mode facilitates automatic winding of the flat wires, and the setting of the size of the stator teeth improves the slot fill factor of the flat wires, and therefore, both the economic cost and the motor performance are considered.
