The utility model discloses during the use, to put the iron core with the tooth structure that stator core slot number equals on, two tooth portions are located the both ends of iron core respectively, detain two tooth go-between respectively on the tooth portion of tooth structure, and the reference column location and the connection in the draw-in groove are passed through in the draw-in groove card on the tooth portion of tooth structure and the tooth go-between. The magnetic steel arranged on the tooth part structure is used for fixing the tooth part on the iron core. And winding can be carried out after the assembly is finished, and the tooth part structure and the tooth part connecting ring are taken down after the winding is finished. The tooth structure and the tooth connecting ring can be recycled.
Furthermore, in order to facilitate the tool to be drawn out and prevent the enameled wire from being scratched, the width of the head part of the jaw of the tool A is smaller than that of the root part of the jaw.
Further, for the frock is convenient for take out, prevents the fish tail enameled wire, frock A and enameled wire contact site surface are smooth and set up the fillet.
The utility model has the advantages that: the utility model discloses simple structure, the wire winding is efficient, and processingquality is high. Because can be with after the wire winding the utility model discloses take off, the stator both ends do not have insulating end plate, have improved the heat dissipation of stator tip, have stopped some hidden dangers that arouse by the skeleton simultaneously. The utility model discloses with low costs, but greatly reduced motor manufacturing cost.

Detailed Description
The invention will now be further described by way of non-limiting examples with reference to the accompanying drawings:
as shown in the drawings, a recyclable insulating end plate comprises a plurality of tooth structures, two tooth connecting rings 2. Every tooth structure includes two tooth portions 1, a tooth portion connecting rod 3, a magnet steel 4, tooth portion connecting rod 3 is the bar structure, two tooth portion 1 is connected respectively tooth portion connecting rod 3's homonymy both ends, two distance between the tooth portion 1 and stator core's high looks adaptation, be provided with the magnet steel groove on tooth portion 1, magnet steel 4 sets up in the magnet steel groove. The tooth part 1 is formed by precisely processing hard alloy materials, and the surface of the tooth part is smooth, so that enameled wires are not damaged when the tooth part is detached. The magnetic steel 4 is neodymium iron boron and is used for fixing the tooth part on the iron core. The tooth part connecting ring 2 is of a circular structure, a plurality of clamping grooves 201 are formed in one end of the tooth part connecting ring 2, the width of each clamping groove 201 is matched with that of the tooth part 1, positioning columns 202 are arranged in the clamping grooves 201, and positioning holes 5 which can be matched with the positioning columns 202 are formed in the end face plane of the tooth part 1. The tooth structure is respectively clamped with the corresponding clamping grooves 201 on the two tooth connecting rings 2 through the tooth parts 1 at the two ends of the tooth structure and is matched and positioned with the positioning hole 5 on the tooth part 1 through the positioning column 202, and the tooth structure is positioned on the inner side of the tooth connecting ring 2.
