Simulation of Switched Reluctance Motor Drive System Based on Multi-Physics Modeling Method

This paper presents a multi-physics modeling of a switched reluctance motor (SRM) drive system. The proposed framework includes a 2-D finite element model to simulate the magnetic field characteristics, and a multi-physics mechatronic model to simulate its electric field and controller properties. The obtained magnetic characteristics are used in the analytical modeling in the form of a lookup table. Dynamic performance parameters for SRM are directly calculated from the co-simulation platform. Current, torque, flux, and radial force under various operational conditions can then be simulated to evaluate the dynamic performance of a switched reluctance drive system. The control algorithm is then realized based on the co-simulation platform. Methodology to evaluate the dynamic performance for the SRM is shown in this paper. A three-phase 12/8 1.5 Kw SRM is used in this paper. Static magnetic characteristics and dynamic performance parameters for the SRM are shown and discussed in this paper.
