For further study of the output-torque 此应建立该电机的参数化模型，详细研究GRM 结 improvement, the parameterized torque-angle model should be built. The parameterized model for the 6-poles GRM was 构参数与矩角特性的关系。 established by the nonlinear magnetic-network method. The A-A A analytical algorithm for the air-gap permeance was studied. 5 Generations of the reluctance matrix and the Jacobin matrix 4 were analyzed in detail. Solution steps of the nonlinear 3 magneti
