Torque analysis of Double-Stator Permanent Magnet Synchronous for Hybrid Electric Vehicle

At present, the in-wheel driving is applied in hybrid electric vehicle (HEV), which brings HEV high efficiency in constant speed area. However, under some special working conditions, the traditional motor can hardly supply enough torque for HEV. This paper presents a new type of double-stator permanent magnet synchronous motor (DSPMSM) for in-wheel driving, so as to improve the performance of HEV. From the view of motor dimension parameters, the concept of split ratio is adopted. Theoretical deduction and simulation experiments are carried out to analyze the split ratio-torque characteristics of this new type of motor.
