Mathematical Models and Simulation of Marine Electric Propulsion Double 3-Phase Permanent Magnet Synchronous Machine

Mathematical models of marine electric propulsion double 3-phase PMSM under double and single 3-phase supply modes were formulated by elaborate deduction, and were transformed into simplified-formed models under dq-ax.es system through double and single 3-phase orthogonal coordinate transformations respectively. Numerical simulation of PMSM supplied with voltages including different harmonics were implemented on the basis of dq-axes models, therefore, the result of simulation was attained with the corresponding conclusion reached.
