Problems solved by technology

[0002] The iron core and coil in the rotor winding of the traditional motor have a large iron core metal ratio, so the mass is heavy. When the motor is running, there are large copper losses and iron losses, and the efficiency is difficult to be greatly improved.
To sum up, the traditional motor has a large energy consumption, and the production efficiency is not high
[0003] In order to reduce the amount of metal used in the iron core, an insulating medium has been used to replace the central part of the iron core in the prior art to reduce the amount of iron used. However, the bonding performance between the insulating medium and the iron core is poor and cannot meet the requirements of the electronic rotor winding.

Embodiment Construction

[0021] Such as figure 1 with figure 2 As shown, the armature rotor core of the four-pole DC permanent magnet motor has a rotor core body 10, the rotor core body has a hollow structure, the hollow part is injected and filled with a resin insulating medium 20, and the resin insulating medium is PVC insulating medium , the PVC insulating medium is formed by directly injecting the hollow part of the rotor core through an injection mold. . The hollow part of the rotor core is a circular structure with clamping grooves 11 distributed on the edge. The rotor core body is automatically punched and riveted by a punching machine. The rotor core is pressed into the shaft 30 by the hydraulic press through the co-clamping device, and the joint part of the shaft and the rotor core is knurled in a strip shape and has a clamping groove structure.

[0022] The preparation process of the armature rotor core is to use a punching machine to automatically punch and rivet the rotor core body to...

Abstract

An armature rotor iron core of a four-pole direct current permanent magnet motor and a preparation process thereof, comprising a rotor iron core body, the rotor iron core body has a hollow structure, and the hollow part is injected and filled with a resin insulating medium. The armature rotor iron core of the four-pole DC permanent magnet motor has less iron core metal body, less copper loss and iron loss, and has the characteristics of high efficiency, light weight, small moment of inertia, high reliability and low cost. It can improve the efficiency of electric energy conversion, improve the distribution of magnetic lines of force, enhance the magnetic density, and improve the overall electrical performance of the motor. It is an upgraded product of the traditional permanent magnet DC motor. The preparation process is simple, and multiple preparation processes are omitted.

Description

technical field [0001] The invention belongs to an armature rotor iron core of a DC permanent magnet motor, and in particular relates to an armature rotor iron core of a DC permanent magnet motor which improves the performance of a four-pole DC armature by utilizing structure and process improvements and a preparation process thereof. Background technique [0002] The iron core and coil in the rotor winding of the traditional motor have a large iron core metal ratio, so the mass is heavy. When the motor is running, there are large copper losses and iron losses, and it is difficult to greatly improve the efficiency. To sum up, the traditional motor consumes a lot of energy, and the production efficiency is not high. [0003] In order to reduce the amount of metal used in the iron core, an insulating medium has been used to replace the central part of the iron core in the prior art to reduce the amount of iron used. However, the bonding performance between the insulating mediu...
