Eco-friendly vehicles can be broadly classified into BEVs, PHEVs, and HEVs according to the proportion of electric motors in the vehicle’s power requirements. Currently, the most common eco-friendly vehicles are HEVs. However, the proportion of BEVs will continue to increase in the future. If the charging time of electric vehicles can be shortened and the mileage per charge can be increased, most future eco-friendly cars will be electric vehicles. Once electric vehicles become popular, both general passenger cars and small electric vehicles for short-distance movement will also become popular. There are many things to consider when designing a motor because a small electric vehicle with low voltage requires a large current to drive the motor due to its small voltage and battery capacity. In this paper, in order to design a low voltage driving motor, a design technique was studied to minimize input current, while considering the back electromotive force of the motor under load. Furthermore, the Finite Element Method(FEA) was used to design the Interior Permanent Magnet Synchronous Motor (IPMSM) to increase power density and reduce torque ripple. In order to verify the validity of this paper, a motor designed with a proposed design technique was manufactured, and its performance characteristics were evaluated.
