Electric Vehicle (EV) can be categorized by the driving method into in-wheel and in-line types. In-wheel type EV does not have transmission shaft, differential gear and other parts that are used in conventional cars, which simplifies and lightens the structure resulting in higher efficiency. In this paper, design method for in-wheel motor for automobiles using Parameter Map is proposed, and motor with continuous power of 5 kW is designed, built and its performance is verified. To decide the capacity of the in-wheel motor that meets the automobile's requirement, Vehicle Dynamic Simulation considering the total mass of vehicle, gear efficiency, effective radius of tire, slope ratio and others is performed. Through this step, the motor's capacity is decided and initial design to determine the motor shape and size is performed. Next, the motor parameters that meet the requirement is determined using parametric design that uses parametric map. After the motor parameters are decided using parametric map, optimal design to improve THD of back EMF, cogging torque, torque ripple and other factors is performed. The final design was built, and performance analysis and verification of the proposed method is conducted by performing load test. ?? ??(in-wheel) ??? ???(in-line) ???? ??? ? ??. ?? ?? ??? ???, ?, ???? ?? ?? ? ? ?? ??? ??? ??? ??? ???? ? ?? ??? ??. ? ???? ?(parameter map)? ??? ??? ?? ???? ?? ??? ????, ???? 5 kW? ???? ???? ?? ? ?? ??? ??. ?? ??? ?? ??? ???? ?? ???? ??? ???? ?? ??? ???, ?? ??, ??? ????, ???? ?? ??? ????. ??? ?? ??? ??? ????, ??? ?? ? ??? ???? ?? ????. ??? ?? ??? ???? ??? ???? ?? ???? ?? ??? ???? ??? ????. ???? ?? ?? ??? ??? ? ???(Total Harmonic Distortion, ??
