A New Hybrid Excited Magnetic Levitation Feeding Platform

Abstract:

Frictional resistance is an inherent problem to traditional feeding platforms of NC machine tools, while magnetic levitation is a good solution. The structure and operating principle of a magnetic levitation feeding platform based on the hybrid excited linear synchronous motor are proposed, and the FEA to the electromagnetic force and normal force of the motor is launched using Maxwell2D. To the problem of force ripple two optimization methods are adopted by simulating to prove the feasibilities of the direct driving by hybrid excited linear synchronous motors and the frictionless feeding of NC machine tools.
