Problems solved by technology

[0010] However, if Figure 4 As shown, when adopting such a winding method in which the main coil / auxiliary coil are each wound in 5 / 4 steps, an electromagnetic force profile (153) reflecting a lot of high-frequency wave components departing from the sine wave will be formed.
As we all know, high-frequency components in the 2kHz band are the main cause of noise and vibration during operation, and there is a problem of increased damage

Abstract

This invention refers to the stator of induction motor, which contains circumference arranged 1-28 holes, rotor iron core formed on holes, stator wound on said holes and generating magnetic field in power switching on, said invention can increase step number of wound line and reduce high frequency part.

Description

technical field [0001] The invention belongs to a stator of an induction motor, in particular to a stator of an induction motor capable of increasing coil steps to reduce high-frequency components. Background technique [0002] Induction motors are usually widely used because of their simple, strong structure and low price. The stator and rotor each have independent coil structures and are driven by mutual electromagnetic induction. [0003] figure 1 is a plan view illustrating a stator core of a stator of an induction motor in the prior art, figure 2 and image 3 are self-explanatory figure 1 The diagram of the winding method of the main coil and auxiliary coil, Figure 4 is the description has figure 1 Contour plot of the electromagnetic field-added force on the stator core of an induction motor. As shown in these figures, the stator core (110) of the induction motor accommodates the rotor core (141) with a certain gap inside. [0004] A shaft hole (142) that can b...
