A motor stator assembly

Abstract

The invention relates to a motor stator assembly, which includes a casing and a stator core; the casing is a cylindrical body with two ends open; the stator core is installed inside the casing, and the stator core includes an iron core yoke part and the core tooth part, the core yoke is an annular structure formed by six core plates connected in series, and the structure size of each core plate is the same; each adjacent two on the core yoke An iron core tooth part is installed on the first card slot and the second card slot close to the joint of the core plate body, and the structure size of each iron core tooth part is the same, and the iron core tooth part includes the first teeth and second teeth. The present invention solves the problem that the copper wires on the teeth of the iron core cannot be completely covered by the winding tape and coated with silica gel, and the exposed copper wires still produce high voltage breakdown of the metal shell and the stator assembly due to partial damage and need to be replaced as a whole. The invention can increase the creepage distance from the copper wire on the iron core tooth part to the metal casing of the motor, improve the insulation performance of the motor, and save costs.

Description

technical field [0001] The invention relates to the field of motor technology, in particular to a motor stator assembly. Background technique [0002] The stator of the motor is the stationary part of the motor. The main function of the stator is to generate a rotating magnetic field. During the rotation of the rotor, the motor is cut by the magnetic force lines in the rotating magnetic field generated by the stator to generate output current. The stator is mainly composed of the stator yoke and the iron core. The stator winding refers to the winding installed on the teeth of the iron core, that is, the copper wire wound on the teeth of the iron core. [0003] Creepage distance refers to the distance between two conductive parts measured along the insulating surface. The copper wire wound on the teeth of the iron core will generate a high voltage during use, and the high-voltage current generated on the teeth of the iron core will To break through the metal shell, in order ...
