      Abstract: In order to solve the problems of large magnetic flux leakage, poor torque quality, difficult and time-consuming design of electromagnetic parameters in the modeling stage, a new type of disc bidirectional flux transverse flux motor is proposed, and a dynamic magnetic network model for solving the electromagnetic parameters of the motor is established. Firstly, the topology and working principle of the motor are introduced, secondly, the corresponding equivalent magnetic network model is established according to the change of the no-load magnetic field in the electric cycle of the motor, the corresponding model is analyzed and calculated, and the theoretical formulas of flux and no-load back electromotive force are derived, and the model analysis and finite element simulation results are compared to verify its accuracy. Finally, a prototype is fabricated and experimentally tested to verify the rationality of the proposed motor structure and the effectiveness of the equivalent model.
