Five-phase permanent magnet synchronous machine operating as generator design, parameter determination by FEM and performance

The paper describes the design and parameter calculation of a five-phase permanent magnet synchronous machine intended for operation as generator connected to the load over a rectifier bridge. The main parameters and machine dimensions are determined using the finite element method in 2 dimensions. Calculated no-load induced voltage and inductances are compared with measured values obtained from a prototype machine. A circuit based mathematical model is also developed and simulated using Matlab/Simulink and the results are used to determine the machine performance as generator. The simulation results are checked versus measured values, and a good agreement between the simulation and measurements was observed. The implemented model gives results with sufficient accuracy, allowing to determine the machine behavior in early design stages. The method described here can be successfully applied for designing and performance calculation of high phase machine.
