Looking onto the concerned issue of the fast pace increase in running costs due to sky rocketing fuel prices and stringent emission norms in the automotive industry, the pre-eminent solution is HEVs and EVs, which henceforth proves to be elucidating. For the deeper study of HEVs and EVs in order to get improvised solutions for the above mentioned issues, the motor forms an indispensable part of it, being the propelling force either full time or by providing part time propulsion to the vehicle. From times immemorial motors are being used in HEVs and EVs as prime force, and the usage of motor has undergone various changes, from DC motors being used initially to AC motors finding applications in present with some special motors. Motors are categorized into three: Elementary DC motors, AC motors and Special motors. Further these motors are contemplated on the basis of theoretical critique and simulations, under various load conditions to examine their congeniality for HEV and EV needs varying from low torque demanding vehicles to ones demanding high torque. The major highlights obtained from simulation of motors and the theoretical analysis are: general overview of the concerned motor, its power and torque delivery, motor behavior on varying load conditions, motor efficiency, energy regeneration efficiency, net cost effectiveness, pros and cons, applications in case of various hybrids and purely electric vehicles. A general layout is thus obtained, to get an idea as to which motor will serve what purpose under various tunings and the suitability of motor for miscellaneous hybrid and electric vehicle applications is procured.
