Armature rotor core of four-pole direct current permanent magnet motor and manufacturing process for same

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...

[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.
