Pre-insertion indexing mechanism for motor stator insulated slot wedge

Abstract

The invention relates to the field of a motor stator for a compressor and in particular to a pre-insertion indexing mechanism for a motor stator insulated slot wedge. The pre-insertion indexing mechanism comprises a temporary storage device. A temporary storage hole is arranged at a position, corresponding to a motor stator slot wedge mounting hole, on the temporary storage hole and is configuredto store the slot wedge. The temporary storage hole facilitates the storage of the slot wedge. After the slot wedge is stored in the temporary storage hole, the pre-insertion indexing mechanism is aligned with the motor stator slot wedge mounting hole. When a force is applied to the slot wedge in the pre-insertion indexing mechanism, the forced direction of the insulated slot wedge rightly faces the slot wedge mounting hole in order to avoid bending the insulated slot wedge during an insertion process, thereby improving the qualified rate of the motor stators.

Description

technical field [0001] The invention relates to the field of motor stators for compressors, in particular to a pre-insertion indexing mechanism for motor stator insulation slot wedges. Background technique [0002] The motor consists of a stator and a rotor arranged in the stator, the stator includes a stator core and a stator winding, the stator core is composed of a rear yoke and teeth, the rear yoke constitutes a cylindrical part of the outer edge, and the teeth are arranged Inside the rear yoke and wind the stator winding. In order to increase the insulation of the stator and thereby improve the electromagnetic conversion efficiency of the motor, it is necessary to insert an insulating slot wedge into the slot wedge mounting hole of the motor stator. [0003] In the prior art, the bottom of the insulating slot wedge is manually aligned with the slot wedge installation hole of the motor stator, and then force is applied to insert the insulation slot wedge into the slot w...

Problems solved by technology

[0003] In the prior art, the bottom of the insulating slot wedge is manually held to align it with the slot wedge mounting hole of the motor stator, and then force is applied to insert the insulating slot wedge into the slot wedge mounting hole. However, due to improper force, the insulating slot wedge often The direction of the force deviates from the slot wedge installation hole, which will cause the insulation slot wedge to bend during the insertion process, thereby reducing the qualified rate of the motor stator
