Abstract

The present invention provides a coil-slot wedge insertion device, which may prevent position deflection of the slot wedge generated when increasing density of coil in stator core slot of an electric motor. According to the invention, when together with winding coils, packing coils inserted into each unit of the slot and inserting the slot wedges for periphery insulation into the stator core, projections for preventing position deflection of the slot wedge are arranged on a slot wedge press face of a slot wedge push bar for pushing an end of the slot wedge to move the slot wedge.

Description

technical field [0001] The present invention relates to a coil-slot wedge insertion device which, in order to meet the demand for high-density winding of coils on the teeth constituting the magnetic poles of the stator core of a motor, is used as the winding step before the coil-slot wedge insertion device. When a high-density wound coil is inserted into the slot, the slot wedge is used to improve the insertion performance of the slot into the slot together with the coil. Background technique [0002] An electric motor consists of a stator and a movable element forming the magnetic poles. Among them, the stator is composed of an iron core composed of a yoke and a plurality of teeth (teeth) as protrusions formed on the inner periphery thereof, and a space called a slot formed between adjacent teeth. The coils wound on the respective teeth form magnetic poles by energizing the respective coils. [0003] The method of winding the coil on the tooth portion generally adopts the...
