A general purpose magnetic levitated platform (MLP) is designed and implemented in this paper. The specifications of the designed MLP include five degrees of freedom control with a normal shift displacement of 10 mm and normal rotation of 2.1 degrees. Within this range, the proposed MLP can be operated in precision position control with high stability. Non-mechanical-contact position and velocity sensors are implemented to control 6 electromagnets in order to offer levitation forces applied onto the embedded permanent magnets in the platform. The MLP is capable of isolating external vibration and eliminating interference from any sources. Both isolation and tracking effects have been tested, and the results are presented in this paper for the proposed magnetic levitated platform.
