Permanent magnet synchronous servo motor stator core forming machining machine and method

Abstract

The invention relates to a permanent magnet synchronous servo motor stator core forming machining machine and method. The permanent magnet synchronous servo motor stator core forming machining machine comprises a base, a bearing unit and a stamping unit, the upper end of the base is provided with the bearing unit, and the stamping unit is installed at the upper end of the bearing unit. According to the invention, the following problems can be solved. The problems include that firstly, when a traditional stator core is machined, silicon steel plates are mostly subjected to stamping treatment in sequence from left to right, so that the silicon steel plates cannot be guided, the silicon steel plates are lack of stability, the silicon steel plates are likely to deviate and warp during stamping machining, and the machining effect is influenced; and secondly, when the current stator core is stamped, residual materials of the silicon steel plates are mostly collected manually, so that safety risks exist, and waste materials of the silicon steel plates are likely to stop in the device, so that the stamping of the silicon steel plates is interfered, and silicon steel plates are likely to be scrapped.

Description

technical field [0001] The invention relates to the technical field of stator cores, in particular to a forming and processing machine and method for stator cores of permanent magnet synchronous servo motors. Background technique [0002] The stator core is an important part of the motor magnetic circuit. It forms the complete magnetic circuit of the motor together with the rotor core, the air gap between the stator and the rotor. The role of the stator core is to serve as a part of the motor magnetic circuit and place the stator Winding, in order to reduce the eddy current and hysteresis loss caused by the alternating magnetic potential in the iron core, the iron core material is generally made of silicon steel sheets. Usually, in order to improve the efficiency and power factor of the stator core, stator slots need to be stamped on its surface, and Improve the performance of the stator core. [0003] However, there are currently the following problems in forming the stato...

AI Technical Summary

Problems solved by technology

[0003] However, there are currently the following problems in forming the stator core: 1. When processing the traditional stator core, most of the silicon steel plates are stamped sequentially from left to right, so batch processing cannot be realized, which affects the stamping efficiency. The lack of stability when stamping the silicon steel plate, so the silicon steel plate is prone to offset and warping, which affects the processing effect;

[0004] 2. Most of the current stator core is stamped by manually collecting the remaining silicon steel plate, so there is a safety risk, and the waste of silicon steel plate is easy to stagnate in the device, and the waste needs to be cleaned repeatedly, which increases the workload If it is not cleaned up in time, it will easily cause the accumulation of waste materials, which will interfere with the stamping of silicon steel sheets, and then affect the processing of silicon steel sheets
