Abstract

The invention discloses a bar-shaped stator and a wiring method thereof. The bar-shaped stator includes a bar-shaped stator iron core, end insulation and coil windings, the bar-shaped stator core includes a stator core unit, and the end insulation includes an end insulation unit , the end insulating unit is installed on the stator core unit and then the coil winding is wound; the stator core unit includes a yoke, and the sides of two adjacent yokes form left and right cut edges, and left and right cut edges The extension line intersects at a point O, which is the bending intersection of two adjacent stator core units; the end insulating unit includes an insulating yoke portion and an insulating tooth portion, and the end face of the insulating yoke portion protrudes to be used for winding coil windings The bridge line of the coil winding is attached to the outer side of the line baffle, and the bridge line of the coil winding passes through the point O, and the bending intersection is used as a reference when wiring the bridge line. Making the bridge wire pass through the bending intersection can not only reduce the defective rate of the stator assembly, but also reduce redundant processes and reduce the production cost.

Description

technical field [0001] The present invention relates to a bar-shaped stator and a wiring method thereof. Background technique [0002] In order to save the iron core material, improve the stator winding efficiency and the full rate of the stator winding slots, the bar-shaped stator has been widely used in the market to replace the circular stator. The bar-shaped stator is generally rounded and welded after winding is completed. The unreasonable arrangement of the bridge wire of the coil winding will affect the product quality of the motor. [0003] The current bar-shaped stator generally includes a bar-shaped stator core, end insulation and coil windings. The bar-shaped stator core includes a plurality of interconnected stator core units 1A, and the end insulation includes a plurality of end insulation units 2A. The insulating unit is installed on the stator core unit and then the coil winding is wound; the stator core unit includes a yoke 11A and a tooth 12A protruding fro...
