A novel toroidal motor with hybrid excitation was proposed in this paper, the special structure and principle of the motor were presented, and characteristics of its magnetic circuit were analyzed. The magneto-motive models were built based on the electromagnetic meshing relationship between inner stator and magnetic teeth of planets, the analytic expressions of electromagnetic parameters and mathematical model were deduced. The model of characteristic analysis was derived by means of matrix analysis, and the dynamic characteristics were simulated. The test of performance parameters for model machine was carried out, the experimental findings and simulation results are well agreed as expected. The results confirm the rationality of the electromagnetic parameters and the correctness of the characteristic simulation. The research is useful for optimum design and controller design further for the novel motor.
