Abstract

The invention relates to the field of motor iron cores, and concretely relates to a direct-current permanent magnet motor iron core. The direct-current permanent magnet motor iron core comprises an iron ring, a wire winding plate, a limiting rod, a sleeve, a bearing, a connecting rod and a fixing frame, first through holes which are evenly distributed are formed in the outer surface of the iron ring, the wire winding plate is slidably connected into the first through holes in the iron ring, a T-shaped through hole is formed in the wire winding plate, the end, located on the outer surface of the iron ring, of the winding plate is rotationally connected with the limiting rod, the bottom end of the limiting rod is located in the T-shaped through hole, the sleeve is arranged in the iron ring and rotationally connected with a motor rotating shaft through the bearing, the connecting rod is hinged to the outer surface of the sleeve, the other end of the connecting rod is hinged to the outer surface of the winding plate, the outer surfaces of the two ends of the iron ring are fixedly connected with the fixing frame, and the fixing frame is fixedly connected with the motor rotating shaft. Movement of the winding rod and the fixing rod is achieved by rotating the sleeve, so the purpose that maintenance personnel can conveniently wind coils with hands is achieved.

Description

technical field [0001] The invention relates to the 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] Due to the structure of the motor itself, the motor is easily damaged after working for a long time. When the winding of the motor is damaged, most motor users will choose to repair i...
