This paper proposes the design of a magnetically levitated planar motor, the configuration of a basic numerical method to embody the control concept, and the design procedure for an experimental test rig. This motor is stable in the levitating direction but unstable in the driving direction because it utilizes the repulsive force between the stator permanent magnets and the moving coils. One problem with magnetically levitated planar motors is the time-consuming nature of the three-dimensional finite element analysis. This analysis requires significant computational resources and can result in significant delays in the design process. To address this problem, a less time-consuming method using Gaussian process regression is presented. In addition, the proposed analysis is verified using a test rig equipped with several sensors. These sensors will provide measurements of static force characteristics and flux linkage to evaluate the performance and effectiveness of the motor under various operating conditions.
