Analytical Model of Permanent Magnet Synchronous Reluctance Motor Taking into Account the Influence of Saturation Effect
The rotor parameters of permanent magnet synchronous reluctance motor are numerous,and it is very complicated to optimize based on the finite element method,while the analytical method is simple and time-saving,but the current analytical model lacks the consideration of the influence of motor saturation effect.To address this problem,a 20kW,4500r/min permanent magnet synchronous reluctance motor is taken as an example for research.Firstly,an analytical model of the motor air gap density is established by the equivalent magnetic circuit method,and the equivalent air gap parameters are added to equate the saturation effect of the motor.Based on the theoretical model calculation results and finite element simulation results to compare the accuracy of the analytical model.
