Rivet-point-free motor stator and rotor piece manufacturing technology

Abstract

The present invention relates to the technical field of motor accessories, in particular to a manufacturing process for a stator and rotor sheet of a motor without riveting points, which includes the following steps: 1) Blanking of the stator and rotor sheet; and the groove shape of the rotor; 2) Stator and rotor punching, which is characterized in that: in the stator and rotor punching step, the guide nail hole, the positioning hole, and the center hole are punched out and then rewound, and then the rewound material is cleaned, After cleaning, it is sent to the mold, and through the dispensing controller, use a special in-mold dispensing head to apply glue to the corresponding position of the rotor piece on the mold; after applying glue, go through the blanking process to combine the rotor pieces together. The rivetless point stator and rotor piece produced by the needle technology of the present invention solves the defects of the motor stator and rotor piece stacking technology in the prior art, and there is no conduction between the stator and rotor pieces of each layer, effectively reducing the generation of eddy currents and reducing the temperature of the motor The increase rate and power consumption have played a role in energy saving and environmental protection.

Description

technical field [0001] The invention relates to the technical field of motor accessories, in particular to a manufacturing process of a stator and rotor piece of a riveting-point motor. Background technique [0002] In the existing motor stator and rotor sheet stacking, a bump (rivet) is made on the silicon steel sheet itself, and each silicon steel sheet is combined with each other by using this bump, so that the silicon steel sheets will be connected to each other. This method will inevitably increase the generation of eddy current, which will increase the temperature rise of the produced motor and increase the power consumption. Contents of the invention [0003] In view of the deficiencies in the prior art described above, the object of the present invention is to provide a manufacturing process for the stator and rotor slices of a rivetless motor. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present inventio...
