Currently, electrification for vehicles such as battery electric vehicles (BEV), plug in-hybrid electric vehicles (PHEV), fuel cell electric vehicles (FCEV) and hybrid electric vehicles (HEV) are attracting a great deal of attention, due to the urgent need to reduce CO2 emissions created from transportation and energy dependency on crude oil. Honda has set a target achieving two-thirds of total global sales as electrified by 2030. A traction motor is one of the essential components for electrified vehicles. Generally, Interior Permanent Magnet Synchronous Motors (IPMSMs) are used as traction motors due to their high torque and power density, high efficiency and ease of use. The design of rotors, which consist of magnets and electrical steel sheets, is important for IPMSMs since not only average torque, efficiency and quietness depend on it, but also cost. We have developed a novel rotor, which allows for a degree of freedom in the shape of the magnets.
