EFFECTS OF NUMBER OF TURNS OF ARMATURE WINDING ON OUTER ROTOR BRUSHLESS DIRECT CURRENT MOTOR DESIGNED FOR AN ELECTRIC VEHICLE PROTOTYPE

While electric vehicles happen to be today's transportation vehicles, big R&D investments are being made by automobile manufacturers. Outer and inner rotor motors are used for electric vehicles. Considering the fact that the transmission systems make the structure more complex, outer rotor motors come into prominence in applications requiring small power. This study includes the design of outer rotor brushless direct current motor for electric vehicle prototypes. In addition, the effects of the number of turns of the armature winding selected, especially on efficiency, input power and torque parameters, were analyzed in detail.
