Vehicle dynamic depends on the power rating as it tallies the required initial acceleration and overall performance. If the vehicle motor operational characteristics provides high torque at constant power, the power rating of the machine can be reduced. Besides, extended constant power range can also recover more kinetic energy during regenerative braking. Therefore, a motor with extended constant power and torque is advantageous for EV and HEV traction application. However, in order to obtain high torque at constant power range, the motors must be specially designed. Thus an Axial Flux Permanent Magnet (AFPM) with dual magnetic circuit is introduced as application specific motor for battery operated electric vehicle. Finite element analysis is carried out for the proposed structure. For the designed value of 1 kW machine it is able to produce 2.5 Nm torque at 150 rpm with a regeneration capability of close to 300V.
