This paper gives the design and simulation of a permanent magnet synchronous motor (PMSM) for a super-high speed centrifugal compressor drive application. The PMSM has an output power of 2000 W at 200,000 rpm with 28 V dc power supply. It is designed for operation at a cryogenic temperature of 77 K. The designed PMSM is a 2-pole, 3-phase slotless structure. The permanent magnet is centrally located...
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...
