In the design of switched reluctance motor for construction machinery,inductance plays a particularly important role as a basic parameter to measure the performance of the motor.The inductance of switched reluctance motor is nonlinear,and direct analysis is difficult.Therefore,under the linear assumption,the magnetic circuit analysis method was used to analyze the permeability component,the calculation formulae of the permeability component at the minimum inductance position and the maximum inductance position were deduced.Then,the calculation formulae of the six rotor special position angles of the inductance of the 12/8-pole parallel-tooth structure switched reluctance motor were deduced,and the inductance analytical curve was obtained.Finally,the calculation results of the motor are compared with the simulation results.The results show that the errors between the inductance calculation results and the simulation results are within 4%,and the relative error of the flux linkage is within 10%,which verifies the accuracy of the analysis and provides a theoretical basis for subsequent motor optimization.
