A Kind of Reluctance Motor Modeling and Multiple Software Coupling Advantages

The inductance of the reluctance motor is nonlinear and the electromagnetic environment is complex and changeable. MATLAB has limited processing capabilities for complex electromagnetic parameters and cannot accurately reflect the actual operating conditions of the motor. A novel reluctance motor is designed and the feasibility of using Maxwell, Simplorer and MATLAB in coupling is studied. Through theoretical calculation and analysis, the mathematical model of the novel reluctance motor is calculated. The motor model is built based on Motor-CAD. Based on Maxwell, the motor parameters are optimized and the ECE model extraction process is explained. Based on Simplorer, a driving circuit model is established. The main circuit model of direct torque control is established based on MATLAB/Simulink, and then coupled for joint debugging. The simulation results show that the torque ripple of the novel reluctance motor based on direct torque control is lower, the coupling simulation analysis of multiple software is feasible, and it can accurately reflect the real-time operating conditions of the reluctance motor and the distribution of magnetic field lines at any time. The diversity of motor design approaches is enriched.
