摘要
We have developed a mathematical model for permanent magnet synchronous motors (PMSMs). The nonlinear characteristics of this model are expressed using a total of eight constants. The magnet flux characteristics of PMSMs can be obtained by using this simplified model. This model can also be transformed into a reverse function, and motor drive simulation including nonlinear characteristics can easily be implemented. Here, we present the simulation results using our nonlinear model. We also demonstrated the effectiveness of the model by simulating estimates of rotor positions based on magnet flux nonlinear characteristics.
