Improving the performance of Permanent-Magnet Assisted Synchronous Reluctance Motor used in electric vehicles

In this paper, the optimization method of changing the rotor structure has been used. In this way changing the parameters related to the rotor structure includes a change in the number of rotor flux barriers, a change in the position of rotor flux barriers, and changing the end angle of the rotor flux barriers. the result of the motor output including torque, Torque ripple, power factor, and cogging torque is calculated. It is shown that torque and power factor Maximization and minimization of torque ripples can be achieved in the design of PMa-SynRM using the FEM Simulations, Taguchi method, and variance analysis method.
