Problems solved by technology

[0002] During the manufacturing process of the motor, it is necessary to insert the enameled wire into the slot of the motor stator to form the stator winding. The existing wire insertion method mainly relies on manual operation. For larger motors, it is more convenient to insert wires, but for small motors , since the motor stator is a cylindrical structure, it is very inconvenient to operate. During the wire embedding process, the edge of the wire slot can easily scratch the paint of the enameled wire, which directly leads to poor performance.

Embodiment Construction

[0011] refer to figure 1 , figure 2 , the present invention is a wire embedding method for a motor stator. A flexible insulating sheet 2 is pre-embedded in the wire slot 1 of the motor stator, and the flexible insulating sheet is distributed along the inner wall of the wire slot 1 to form a guide groove 21. The edge of the sheet protrudes from the axial opening and radial opening of the slot 1, insert the enameled wire 3 into the guide groove 21, and pull out the flexible insulating sheet after the wire embedding is completed; the flexible insulating sheet 2 is composite film, nylon film or plastic film; the enameled wire 3 is embedded in the guide groove 21 by hand or by a wire inserting machine. After the flexible insulating sheet is used, it can prevent the edge of the stator slot 1 from scratching the paint skin of the enameled wire 3, which greatly improves the performance of the motor; the flexible insulating sheet 2 is made of composite film, nylon film or plastic fil...

Abstract

The invention discloses a wire inserting method for a motor rotor. A flexible insulating strip is embedded into a slot of the motor rotor in advance; flexible guiding sheet is circularly distributed along the inner wall surface of the wire groove to form a guiding groove; and an edge part of the flexible guiding sheet extends out of an axial opening and a radial opening of the slot. An enameled wire is inserted into the guiding groove, and the flexible guiding sheet is pulled out after wire inserting. The wire inserting method can effectively prevent enameled leather of the enameled wire frombeing scratched and greatly improve the motor performance.

Description

technical field [0001] The invention relates to a wire embedding method for a motor stator. Background technique [0002] During the manufacturing process of the motor, it is necessary to insert the enameled wire into the slot of the motor stator to form the stator winding. The existing wire insertion method mainly relies on manual operation. For larger motors, it is more convenient to insert wires, but for small motors , Since the motor stator is a cylindrical structure, it is very inconvenient to operate. During the wire embedding process, the edge of the wire slot can easily scratch the paint of the enameled wire, which directly leads to poor performance. Contents of the invention [0003] The problem to be solved by the present invention is to provide a wire embedding method for the motor stator, which can effectively prevent the paint skin of the enameled wire from being scratched, and greatly improve the motor performance. [0004] In order to solve the above techni...
