Model Structure and Simulation Analysis of a Novel Magetic Suspension Spindle Apparatus for Micro EDM

Article Preview

Abstract:

In the Micro Electronic Discharge Manufacture (The diameter of electrode is no more than 0.5mm), the response frequency of the spindle in Z axis is too low to satisfy the requirement of rapid response. Considering this problem, a novel spindle apparatus based on the Magnetic Suspension drive principle is proposed in this paper, the basic structure and principle are introduced. At the same time, the Magnetic field distribution and they are analyzed by the finite element software Ansoft Maxwell. Theory conduction and simulation results indicates that the response frequency of the spindle and the electromagnetic forces satisfy the design requirement, the novel spindle can shift in a small range around the equilibrium position, and there is no magnetic coupling effect in each other degrees of freedom of the spindle, so the independent PID algorithm can be used in the control of each degree.
