In-series concentrated wound motor public end processing method and motor insulating framework

Abstract

The invention discloses an in-series concentrated wound motor public end processing method and a motor insulating framework. The motor insulating framework is of a circle structure, is used for fixing a three-phase wounding and comprises an outer side wall, an inner side wall and a bottom plate, wherein the outer side wall and the inner side wall are connected through the bottom plate; the outer side wall is provided with a plurality of U-shaped open grooves for holding puncture terminals communicated with any two wound lines of the three-phase wounding in a riveting manner; boss buckling points are arranged between every two adjacent open grooves; the boss buckling points are used for positioning any one wound line of the three-phase wounding. The processing method adopts the motor insulating framework and comprises the following steps: respectively communicating any one wound line of the three-phase wounding with the other two wound lines through the puncture terminals in a riveting manner; putting the puncture terminals at the opening grooves in the outer side wall of the motor insulating framework after being communicated with two wound lines in the riveting manner; positioning any one of the wound lines of the three-phase wounding through the boss buckling points on the outer side wall of the insulating framework. By adopting the processing method, the efficiency in motor production and the operation reliability of the motor are improved.

Description

technical field [0001] The invention relates to the technical field of electric motors, in particular to a method for processing the common end of a series-wound motor and an insulating skeleton of the electric motor. Background technique [0002] The existing common treatment method for the connection of the common end of the three-phase series concentrated winding frequency conversion motor is to first remove the enameled wire paint at the end of the A, B, and C three-phase windings, then kink the three-phase windings, solder them with solder, and finally wrap them with a large sleeve Weld the location and insert the large sleeve into the winding bracts medium process. [0003] The insulating frame is better stuck on the upper and lower end faces of the stator core through appropriate matching dimensions, which can well support and insulate the enameled wire. [0004] However, the existing method of processing the common end of the motor and the insulating frame are incon...

AI Technical Summary

Problems solved by technology

[0004] However, the existing method of processing the common end of the motor and the insulation frame are inconvenient to use, and the three-phase windings are kinked and soldered with more processes, which is time-consuming and laborious, which limits the efficiency of motor production.
