Direct-current permanent magnet motor iron core

Abstract

The invention belongs to the technical field of motor iron cores, and particularly relates to a direct-current permanent magnet motor iron core. The direct-current permanent magnet motor iron core comprises an iron ring, a winding rod, an arc-shaped clamping rod, a columnar groove body and a piston plate, wherein an annular cavity is formed in the iron ring; a plurality of groups of arc-shaped through grooves communicated with the annular cavity are uniformly formed in the outer edge of the iron ring; the winding rod is inserted into the arc-shaped through groove; a connecting hole is formed in the position, which is close to the bottom end, of the winding rod; a rotating ring is attached to the side face of the iron ring; a driving rod is fixedly arranged on the edge of the surface, whichis close to the iron ring, of the rotating ring; and the driving rod penetrates through the arc-shaped through groove in the iron ring and is inserted into the connecting hole in the winding rod. According to the invention, coil replacement is facilitated, the iron ring and the winding rod can be used as molds for coil production in a factory to produce coils in batches, a user can directly purchase finished coils conveniently and replace the coil by himself / herself when the coil is damaged, convenience and quickness are achieved, and a motor does not need to be sent back to a manufacturer tobe replaced.

Description

technical field [0001] The invention belongs to the technical field of motor iron cores, in particular to a DC permanent magnet motor iron core. Background technique [0002] The fixed part of the motor is called the stator, on which a pair of stationary main magnetic poles of DC excitation are installed; the rotating part is called the armature core, on which the armature winding is installed, and the induced electromotive force is generated after power-on, acting as Rotating magnetic field; after that, electromagnetic torque is generated for energy conversion. According to the shape of the stator winding and the way of embedded installation, the stator winding can be divided into two types: centralized and distributed according to the shape of the coil winding and the way of embedded wiring. [0003] The patent application number CN201911319778.8 proposes a DC permanent magnet motor iron core, including an iron core group, a flow guide mechanism, a limit mechanism, a clam...

AI Technical Summary

Problems solved by technology

[0004] In order to make up for the deficiencies of the existing technology and solve the problem that the coil cannot be replaced directly after the coil is burned, and the iron core and the coil need to be replaced at the same time, resulting in waste, a DC permanent magnet motor iron core proposed by the present invention
