Abstract: The ETC (Electric Turbo Charger) consists of high speed PMSM, ball or air foil bearings, impeller and controller. KERI (Korea Electrotechnology Research Institute) is developing a high speed surface permanent magnet (SPM) type of synchronous motor and a Pulsed Width Modulation (PWM)-driven inverter. This system operates at a power density of 3 kW/kg at 100,000 rpm and is intended to fit the 1,600 cc diesel vehicles to reduce turbo-lag within 0.5 s. The design and analysis of the PMSM for the ETC has been developed successfully considering the several losses and current overload rates using transient computational fluid dynamics (CFD).
