This paper shows that the split ratio of the stator inner diameter to the outer diameter has an influence on the air-gap flux density, stator copper loss, thermal load, torque density and cost for interior permanent magnet synchronous motors (IPMSMs) applied in electric vehicles (EVs). This paper presents a simplified analytical method to study the optimization of the split ratio considering both the efficiency and cost. The validity of this method is verified by experiment on a 35kW prototype.
