dc.description.abstract	This paper presents an electromagnetic performance analysis method for fast dynamic simulation of a bearingless permanent magnet motor (BPMSM) based on model order reduction (MOR). The electromagnetic characteristics and dynamic behavior model of the rotating machine are constructed by using the MOR based on proper orthogonal decomposition. First, the q-axis and d-axis currents and rotor angle of the motor are scanned to construct the magnetic field distribution snapshot matrix. Then singular value decomposition of the snapshot matrix is used to calculate the basis vectors. Finally, the order of the system is reduced by selecting an appropriate truncation order of the basis vectors. Compared with the finite element method (FEM), the calculation time of MOR for the BPMSM is significantly reduced. At the same time, it can provide accurate results of magnetic field distribution, electromagnetic force, levitation force and dynamic response. Through analysis and comparison, the results of the proposed method match well with the FEM simulations.

Abstract:

This paper presents an electromagnetic performance analysis method for fast dynamic simulation of a bearingless permanent magnet motor (BPMSM) based on model order reduction (MOR). The electromagnetic characteristics and dynamic behavior model of the rotating machine are constructed by using the MOR based on proper orthogonal decomposition. First, the q-axis and d-axis currents and rotor angle of the motor are scanned to construct the magnetic field distribution snapshot matrix. Then singular value decomposition of the snapshot matrix is used to calculate the basis vectors. Finally, the order of the system is reduced by selecting an appropriate truncation order of the basis vectors. Compared with the finite element method (FEM), the calculation time of MOR for the BPMSM is significantly reduced. At the same time, it can provide accurate results of magnetic field distribution, electromagnetic force, levitation force and dynamic response. Through analysis and comparison, the results of the proposed method match well with the FEM simulations.
