| Modern high-quality CNC machine tools put forward higher and higher requirements for linear feed servo systems, and it is of great significance to study the direct drive technology of linear servo motors. At present, relevant institutions have analyzed the reasons for the thrust fluctuation of the high-thrust permanent magnet linear servo motor for machine tools: based on the finite element electromagnetic field calculation theory, the electromagnetic field and thrust fluctuation of the linear motor are calculated, and the electromagnetic design and Mechanical design. The linear motor drive system model is designed and manufactured using the DSP chip TMS320LF2407A. The end effect and cogging effect are the main reasons for the thrust fluctuation of the permanent magnet linear servo motor. The end effect and cogging effect of the large thrust linear servo motor are more significant, and the thrust fluctuation is more serious. In order to weaken the thrust fluctuation of the permanent magnet linear servo motor, this paper adopts a permanent magnet linear servo motor design method based on flux modulation. The primary of the motor adopts an open slot, and the cogging flux The guided waves are evenly distributed in an odd number of permanent magnet poles. The combination of permeance modulation method and fractional slot winding theory is applied to the design of permanent magnet linear servo motor, which effectively weakens the thrust fluctuation caused by the end effect of permanent magnet linear servo motor. After years of exploration and practice, Ningbo Ruixing Motor Co., Ltd.'s motor has become more complete, with better and better performance in all aspects. In particular, the performance of high-power motors reaches or approaches well-known foreign brands, and can be designed and manufactured according to your special needs. |
