Current Reduction Design and Analysis of In-Wheel Type Vehicle Traction Motor for High-Speed Operation Region

This paper presents a improved method for designing and Analyzing a high power In-Wheel type motor that is applicable to electric vehicles traction. A In-Wheel type motor was made before this paper written. But, it has a problem that input current for field weakening in high-speed range is too much. So, this paper proposed the current reduction design and analysis of In-Wheel type vehicle traction motor for high-speed operation region. To apply for the electric vehicles, a form, a tire, and a wheel of vehicles are considered when calculating a motor performance. After calculating a motor performance, the novel model is compared with the conventional model. Characteristics analysis and FEA(Finite Element Analysis) are used for Improved designing In-Wheel motor
