Automatic wire plugging structure of flat-wire motor stator

Abstract

The invention discloses an automatic wire plugging structure of a flat-wire motor stator. The automatic wire plugging structure comprises a vertical guide pillar and three support bases sequentially fixed onto the guide pillar from top to bottom, and a slide base bearing a stator core is arranged above the third support base; a slide pin guide is fixed on the second support base, radial slide chutes evenly distributed in a ring are arranged in the upper end of the slide pin guide, and a slide pin capable of sliding radially along each slide chute is placed in the slide chute; a sliding extrusion body is embedded in the outer side of each slide pin; a press component is arranged on the first support base. The automatic wire plugging structure is ingenious in structure and simple and reliable, production efficiency can be improved, the possibility that enameled flat wires are scratched during the course that a winding coil is plugged in the stator core is reduced, insulation reliabilityamong the enameled flat wires is improved, and use of insulation paper among the enameled flat wires in the chutes is favorably avoided.

Description

technical field [0001] The invention relates to a stator winding of an automobile drive motor or a generator, in particular to an automatic wire insertion structure for a flat wire motor stator. Background technique [0002] The winding of the flat wire motor is a square wire, and the winding coil is generally embedded in the stator slot by insertion, such as figure 1 Shown is a schematic view of the stator slots inside the stator core. In the prior art, the stator wire insertion method of the flat wire motor is generally that a single coil a is inserted into the stator slot of the stator core b one by one, such as figure 2 As shown, the coil inserted later is easy to scratch the coil that has been inserted. In order to ensure the insulation reliability between the enameled flat wires, each wire should be separated by insulating paper c. This wire insertion method is not easy to realize automation, and production efficiency is lower. Too much insulating paper in the slot...

Problems solved by technology

In the prior art, the stator wire insertion method of the flat wire motor is generally that a single coil a is inserted into the stator slot of the stator core b one by one, such as figure 2 As shown, the coil inserted later is easy to scratch the coil that has been inserted. In order to ensure the insulation reliability between the enameled flat wires, each wire should be separated by insulating paper c

This insertion method is not easy to automate, and the production efficiency is low

Too much insulating paper in the slot will reduce the slot fullness of the motor. The more wires in the slot, the lower the slot fullness of the motor. It is difficult to reflect the advantages of high stator slot fullness of the flat wire motor, and to a certain extent restricts the winding wire Dimensional Design Flexibility
