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 pr...

Abstract

The invention discloses an armature rotor core of a four-pole direct current permanent magnet motor and a manufacturing process for the same. The armature rotor core comprises a rotor core body, wherein the rotor core body has a hollow structure in which a resin insulating medium is injection-molded and filled. The armature rotor core of the four-pole direct current permanent magnet motor adopts fewer core metals, ensures relatively lower copper loss and iron loss, has the characteristics of high efficiency, light weight, low rotational inertia, high reliability and low cost, can improve electric energy conversion efficiency, improve the distribution of magnetic lines of force, enhance magnetic density and improve the overall electrical properties of the motor, and is an upgraded product of the conventional direct current permanent magnet motor. The manufacturing process for the armature rotor core is simple, and a plurality of manufacturing steps are saved.

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...
