Abstract :
An interior permanent magnet motor is a good option for traction application related to the induction motor and switched reluctance motor because of high mechanical rigidity and low demagnetization risk. the design of this kind of motor is attractive for engineer despise the implementation cost of them in high constant speed power range (CPSR) is high. in this paper using combination of two ideas i.e. non conventional air bridge and segmented permanent magnet a optimal design has been proposed. in this paper non conventional air bridge is used for reducing the permanent magnet volume. the genetic algorithm has been applied to the goal function. simulation results show the good performance of optimal design related the conventional design.
