Description

technical field [0001] The invention relates to the technical field of motor component processing, and specifically proposes a motor rotor die-casting manufacturing process. Background technique [0002] The motor is composed of two parts, the rotor and the stator. It is used to realize the conversion of electrical energy and mechanical energy and mechanical energy and electrical energy. The motor rotor is the rotating part of the motor. The motor rotor can be divided into motor rotor and generator rotor. The motor rotor is mainly composed of iron core, rotor winding and rotating shaft. Since a thicker large iron core will cause greater eddy current damage and reduce the motor torque, the motor rotor is usually composed of several ferromagnetic conductor sheets. As a result, the eddy current loss can be significantly reduced, so the motor rotor widely adopts the laminated iron core structure; in order to adapt to mass production, the motor rotor laminates can be processed by...

Problems solved by technology

The motor rotor is mainly composed of iron core, rotor winding and rotating shaft. Since a thicker large iron core will cause greater eddy current damage and reduce the motor torque, the motor rotor is usually composed of several ferromagnetic conductor sheets. As a result, the eddy current loss can be significantly reduced, so the motor rotor widely adopts the laminated iron core structure; in order to adapt to mass production, the motor rotor laminates can be processed by punching or die-casting. During the forming process, the burrs cannot be completely avoided at the position of the slot hole on the motor rotor sheet for winding the rotor winding, and the surface of the motor rotor laminations needs to be coated with an insulating coating. The burrs on the motor rotor laminations will not only affect the coating. layer effect and appearance aesthetics, and will reduce the accuracy of lamination assembly and stacking, resulting in the failure of the motor rotor laminations to form a tight lamination structure, so it is necessary to further treat the surface of the motor rotor laminations after die-casting. In the traditional In the process of processing, manual grinding is often used, the efficiency of manual processing is very low, and improper grinding techniques will cause damage to the motor rotor laminations, thus affecting the dimensional accuracy and appearance aesthetics to a certain extent
