Recently, Inner permanent magnet (IPM) synchronous machines have been introduced as a possible traction motor in hybrid electric vehicle (HEV) and traction applications due to their unique merits. In order to achieve maximum torque per ampere (MTPA), optimization of the motor geometry parameters is necessary. This paper Presents a design method to achieve minimum volume, MTPA and minimum value of cogging torque for traction IPM synchronous machines and simulation in order to extract the output values of motor is done using 3D-Finite Element Model, that has high level of accuracy and gives us a better insight of motor performance. Then presents back EMF, power factor, cogging torque, Flux density, torque per ampere diagram, CPSR (constant power speed ratio), torque per speed diagram in this IPM synchronous machine. This study can help designers in design approach of such motors.
