Problems solved by technology

However, the straightness of the inner diameter of the stator core assembled by welding is difficult to control, the number of times of machining and grinding of the inner diameter increases, and there are burrs in the welded part
Moreover, the local high temperature at the welding place is easy to deform the iron chips, and the insulated iron chips increase the eddy current loss of the stator core due to the conduction at the welding place, which will reduce the performance of the motor

Embodiment Construction

[0026] Now further illustrate specific embodiments of the present invention in conjunction with accompanying drawings. Fig. 4 shows the process of assembling the stator core by bonding method of the present invention. As shown in FIG. 4 , the new method for assembling the stator core of the motor involved in the present invention completes the assembly of the stator core through the assembly procedure of positioning lamination, bonding molding and assembling.

[0027] Position the lamination, stack the iron sheets together and align the inner diameter and outer circle of the iron sheets through mold positioning.

[0028] Adhesive molding, applying adhesive around the iron core formed by positioning laminations of iron chips, so that the iron core is bonded and formed. The binder used is insulating varnish for motor impregnation.

[0029] Assemble into one, press the bonded and formed iron core from both ends of the iron core at a high temperature where the insulating paint i...

Abstract

The invention relates to a method for assembling iron core of motor stator. Wherein, it comprises: layering iron core plates and positioning them with module to align the inner diameter and outer round; coating insulated dope around the iron core as adhesive to adhere and shape the iron core; compressing the two ends of iron core at high temperature and high pressure. The invention can realize small seam, high connecting strength, non burr, high linearity, and improve the motor property.

Description

technical field [0001] The invention relates to a motor, in particular to a method for assembling the stator iron core of the motor. Background technique [0002] A motor is a device that converts electrical energy into mechanical energy, mainly through the rotation of components under the action of a current magnetic field to convert electrical energy into rotational mechanical energy. Therefore, motors have become important components of many household appliances, such as air conditioners, washing machines, dishwashers, etc. In the air conditioner, the motor is the power supply source for the operation of the compressor in the refrigeration cycle system and the operation of the fan in the air cycle system. In the washing machine, the motor drives the drum or the pulsator to rotate to realize the washing, rinsing and dehydration of the clothes. In the dishwasher, the motor drives the water pump to spray water onto the dishes to clean the dishes. [0003] Generally speaki...
