Abstract

This paper presents model-based control (MBC) analyses of a bearingless interior permanent magnet motor (IPMM). The motor is capable of producing 100 kW power for use in high-speed applications in industries. The maximum speed of the motor is 22000 rpm. Motor’s initial parameters are obtained through Finite Element Method (FEM) analyses. State-space models, controller and observer matrices are built based on the optimal, operating points obtained from FEM analyses. Thereafter, the rotor’s magnetic levitation characteristics are analyzed through digital control strategies. Performances of the controlled system are recorded and subsequently discussed.
