Effects of Magnet Type and Thickness on Outer Rotor Brushless Direct Current Motor Designed by Calculating the Required Motor Power for an Electric Vehicle Prototype

Abstract

While electric vehicles are taking their place as 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 organs 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 magnet type and magnet thickness on the design were analyzed in detail. The effects of magnet type and magnet thickness selected in the design of outer brushless direct current motor can be observed from the results, especially effecting power and torque parameters.
