| Research Abstract |
This study focuses on development of an ultra high-speed motor to make automotive superchargers and turbochargers electrified or hybridized. Extremely special design is required to achieve low-voltage, high-current and high-frequency operation because of the automotive application. In addition, high-power density and high-efficiency design must be consistent with the above requirements. Using FEM based electromagnetic analyses, a prototype has been developed, which has 1.5-kW rated output power, 3-kW peak output and 150,000 r/min top speed specifications when operated with a 12-V DC power supply. This model has achieved the world’s top level power density of 22.2 W/cm3(at the rated output power) as well asthe 98.1 % electrical efficiency by employing a 2-turn slotless configuration.
