Design of PMSM for EVs with its Mechanical Aspects

Electric machines are the main component of electric vehicles when performance of the system is being considered. Various thermal and mechanical aspects plays a vital role in the consideration of design of the machine. Now a days, various key parameters in designing of electrical machines got special attention when the efficiency and torque calculation has been incorporated. It is found that slight change in the physical dimension of constituent parts of the electric machines affects the key parameters and provide a way for designers to enhance the performance with all respect. This paper mainly focuses on the designing along with the mechanical aspects of Permanent Magnet Synchronous Machines (PMSM) by variation in the constituent physical change in the parameters. The paper also introduces the optimistic parameters by trial and error method. In the world, various countries uses different types of electric motors such induction motors, switch reluctance motors and wound field synchronous machines as per the vehicle requirements. Japan is only country incorporates the use of Permanent magnet machines instead of induction machines just because of their efficiency and its stability over wide conditions. In this research work, the performances and designing has been carried out with the help ANSYS 16.2 (Electromagnetic). The software provides large no of minor as well as major parameters variation thereby giving the results in the form of graphical representation.
