A coupled electromechanical dynamic model for a working platform Supported by an active magnetic guide (AMG) is set up according to the special stiffness and damping theory of maglev system and the unique vibration of the working platform for a machine tool. The dynamic characteristics of a working platform Supported by an AMG are studied using different groups of control parameters. Results show that the dynamic characteristics of the platform system, such as critical vibration frequency, vibration mode and so on, can be improved by adjusting the control parameters. This research offers theoretical support for ultra-high-speed and ultra-precise machine working platform designs, including the structure of platforms, the design of electromagnets, and the establishment of the control parameters.
