Title:
COIL, STATOR, AND MOTOR
Document Type and Number:
WIPO Patent Application WO/2021/169448
Kind Code:
A1
Abstract:
Disclosed is a coil. The coil is formed by winding a wire; one end of the wire forms an input end of the coil, and the other end thereof forms an output end of the coil; the output end extends out of the coil along a first direction and can be connected to an input end of an adjacent coil in a same phase winding on a stator core; the first direction is an arrangement direction of the coil on the stator core. The coil provided in the present utility model is simple in structure, the output end of the coil extends out from one side of the coil and can be connected to the input end of the adjacent coil in the same phase winding on the stator core, and welding between two adjacent coils can be achieved only by means of one welding point, thereby reducing the welding points, improving the reliability of connection between the coils in the winding, and improving the stability of an entire stator. In addition, the structure of the coil can be designed in a standardized model, thereby facilitating mechanical assembly and automatic production and achieving convenient mounting and high mounting efficiency. Also disclosed are a stator and a motor.
