This project focus on the mathematical model, performance characteristics, detent force optimization and design methods of the novel flux reversal planar motor. Firstly, the electromagnetic analysis and simulation model of the motor will be established. On the basis, the thrust, loss and temperature characteristics of the motor is studied; the influence of the main size of the motor on the thrust density is investigated. The research on characteristics of the detent force of the motor and suppression methods will be carried out. The influence of pole pitch, tooth width, pole arc coefficient on the thrust density of the motor is analyzed respectively, and the optimal design of the mechanical structure and cooling structure are also considered. Finally，the performance evaluation and analysis is achieved based on the prototype test. According to the above analysis and investigate, optimization design criterions are expected to obtain, which can provide a reference for practical engineering.
