Problems solved by technology

But the insulation layer is easy to break and fall off during the operation of the induction motor
The fragments of the insulation layer will rub against the rotor and stator under the high-speed rotation of the induction motor rotor, causing the induction motor to burn out
Therefore, the packaging method of the stator of the known induction motor not only does not allow the insulation layer to fully function, but also causes the failure time of the induction motor to be premature

Abstract

Disclosed is a packaging method of an induction motor stator. The packaging method comprises the steps of arranging the induction motor stator in a machine shell, wherein the stator comprises a statoriron core, and a stator winding which surrounds the stator core; pouring a first insulating material into the machine shell to form a first insulating layer, wherein the first insulating layer directly covers the stator winding; and pouring a second insulating material in the machine shell to form a second insulating layer, wherein the second insulating layer covers the first insulating layer. The shrinkage rate of the first insulating material is smaller than that of the second insulating material.

Description

technical field [0001] The invention relates to a packaging method and structure of an induction motor stator, in particular to a packaging method and structure capable of improving the heat dissipation effect and packaging strength of the motor stator. Background technique [0002] It is known to enclose the stator of an induction machine by covering the stator windings with an insulating material to form an insulating layer on the stator windings. The function of the insulating layer on the stator winding is to protect the stator winding and insulate the conductive part of the stator winding from the stator core, so that the stator of the induction motor can operate normally. But the insulating layer is easy to break and fall off during the operation of the induction motor. Fragments of the insulation layer will rub against the rotor and stator under the high-speed rotation of the rotor of the induction motor, causing the induction motor to burn out. Therefore, the known...
