Abstract: This paper describes a program development in testing a 100 kW Permanent Magnet Synchronous Motor (PMSM) using multi-leaf foil bearings with bump foils. The testing program includes the motor speed up to 43000 rpm, and then slow down to zero speed. The orbit of the rotor and the electrical parameters of the motor are obtained. The success in the experiments shows that the design and fabrication of the compliant gas foil bearings and motor can provide a useful guide to the development of an advanced high speed rotating machinery.

Keywords: High-speed, permanent-magnet synchronous motor, multi-leaf foil bearings
