Abstract

This paper gives the analysis and test of a surface mounted axial flux permanent magnet synchronous motor (PMSM) for a high-speed centrifugal compressor drive. Both analytical analysis and 3-D electromagnetic finite element method (FEM) are used to calculate flux density in the airgap, rotor back iron, and stator iron. 3-D FEM is used to simulate the electromotive force (back EMF) and torque. The motor has been tested up to 87,000 rpm using an open-loop controller. The advantages and disadvantages of this kind of structure are analyzed, and some improvements of this design are also considered and partially verified by experiments
