英文摘要： Recently the problem of excessive energy consumption and serious environment pollution are increasingly outstanding, energy saving has been involved in seven strategic emerging industries. The air compressor is widely used in more industrial areas, its electricity consumption representing more than 10% of the national generation, but the air compressor driven by high speed motor can remove gearbox, so its volume can decrease by 60-70%, and saving over 20% energy. Hence, the exploration and research of high speed motor and its key technologies, which have advantages of high reliability, efficiency and integration, become research focus of home and abroad. Based on preliminary study, the outer PM rotor claw pole high speed motor with square wave supply is proposed. It not only has all the advantages of conventional high speed PM motor, but also easily realizes integrated design due to outer rotor,so the high reliability and small size can be obtain. The limits of inverter maximum frequency are broken by square wave supply, so the motor speed is increased, and it has broad application prospects. In this project, the complete theoretical system of this kind of novel machine will be established through by the research on loss calculation at stator and rotor, ventilation and cooling, dynamics analysis, optimal design
