This paper deals with the weight reduction design of In-Wheel type motor. Therefore, characteristic and weight of motor according to change in reduction gear ratio are examined. The weight of construction and reduction gear following the increase of gear ratio are also considered. Weight of motor is minimized by modulating the ratio of stack length and external diameter of stator. Then, In-Wheel motor geometry based on the prototype motor is optimized to get the determined parameters using response surface methodology (RSM) and Finite Element Method (FEM). Optimal design of core usage in rotor is conducted for minimizing weight of motor which has identical characteristic to prototype motor. Characteristic analysis is conducted by using equivalent circuit analysis of PM type motor. Through the presented weight of In-Wheel type motor, total weight is reduced to 25% of prototype motor.
