Abstract

The invention relates to the technical field of motors, and provides a stator punching sheet, a stator assembly, a motor and a household appliance. The stator punching sheet comprises a stator tooth part, wherein the stator tooth part comprises a gear ring and a plurality of stator teeth distributed along the circumferential direction of the gear ring; the stator teeth comprise a plurality of first stator teeth, each first stator tooth comprises a first tooth part and a second tooth part which are connected with each other, and the joint of the first tooth part and the second tooth part is bent; and the two first tooth parts in the same group deviate from the direction of the diameter of the end, connected to the gear ring, of the first stator tooth, and extend towards the side where the first tooth parts are located. According to the stator punching sheet, the stator assembly, the motor and the household appliance, the height of a coil extending out of the end part of a stator core is reduced, the end leakage inductance is reduced, the coil is saved, winding is simple, and the utilization rate of a wire duct is improved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to stator punching sheets, stator assemblies, motors and household appliances. Background technique [0002] The motor is an electromagnetic device that realizes electromagnetic conversion or transmission according to the law of electromagnetic induction. It converts electrical energy into mechanical energy and provides driving torque. It is an important part of the field of mechanical manufacturing. [0003] The motor includes: stator, rotor and other accessories; among them, the stator is an important part of the motor. The stator winding of the motor generally has the problems that the winding protrudes from the end of the stator core, the leakage inductance is large, and the coil consumption is large, and the winding process is complicated, the requirements for workers are high, the winding quality is difficult to control, and the production efficiency is low. High, leading to l...
