Abstract：This study discusses the features of the linear motor compensation mechanism, In particular, (1)response speed, (2)positioning, and (3)motion force. The mechanism uses Finite-Element software to carry out structural analysis and find a solution. It also uses the built-in Design Optimization module to adjust the required parameters to obtain the optimal configuration under a limited space and objective value. The finite element method was applied to simulate the relationship between induction coin and its motion distance according to different sized air gaps. Experiments were conducted to confirm the relationship. Results revealed that both experiments and analysis obtained the same trend for electromagnetic force. In considering air gap of the design of electromagnetic platform, both electromagnetic force and responding speed can meet the requirements when air gap is 0.1 mm and 0.2 mm. When the air gap was 0.2 mm, and motion distance of coll was 0.5 mm, the error value was 10.34%. Electromagnetic force was still acceptable according to industrial standards, however, and response speed also exceeded the required value.
