The electricallyassisted turbocharger with external motor can be realized with little change on the structure of traditional turbocharger. It has the advantages of simple electric transformation and small thermal load of motor, which is one of the important technical routes of electricallyassisted supercharging. The matching method of highspeed permanent magnetic motor and turbocharger was proposed based on the acceleration performance target. An overrunning clutch was then designed to connect and disconnect the highspeed motor and turbocharger. A dynamics model of rotorbearing system for electricallyassisted turbocharger was built and the analysis of rotor stability was carried out. The integration of electricallyassisted turbocharger was conducted and a prototype was produced. The study of acceleration response for electricallyassisted turbocharger were further carried out. The experimental results showed that turbocharger response time reduced by 25.9%.
