一种同步直线电机推力波动特性的检测方法
A Method for Detecting the Thrust Fluctuation Characteristics of Synchronous Linear Motors
摘要
Abstract
The thrust fluctuation mainly affects the motion performance of linear motors. The precision test of the thrust fluctuation thus forms an important prerequisite in the design and control of linear motors. The traditional test mainly adopted the ball screw and the rotary motor, but the torque fluctuation of the rotary motor and the bad transfer efficiency of the ball screw greatly affect the test precision. By analyzing the electromagnetic force characteristics of synchronous linear motors with electromagnetic models and the finite element method, in this paper, a novel thrust fluctuation test method was proposed. The proposed method used two linear motors of the same type to be connected and to be the load mutually,then the thrust fluctuation of the tested motor was measured by adjusting the relative position. By result comparison under different experimental conditions, the suitable connecting mechanism was designed. The maximum static thrust was detected and the thrust fluctuation characteristics were analyzed by Fast Fourier Transform and digital filters. The results show that the detection method has a simple test structure and good test performances, and the proposed method is superior to the traditional ones.关键词
