Design and analysis of a high-speed machine for air compressor

This paper describes the design and analysis of a high-speed permanent magnet machines for a 130 kW,31 500 rpm class air compressor. According to the design criterion of high-speed motor,chose the material of motor and calculate the size parameters of the machine with magnetic circuit method. Using finite element software ,the electromagnetic field of this prototype are analyzed and stator and rotor loss are calculated at the same time. And then ,by analyzing the sheath material and magnetization manners of the permanent magnet,to reduce the motor internal loss,reduce the temperature and improve the motor performance.
