Calculation of winding voltage of permanent magnet synchronous generator based on Tooth Flux Method

The calculation method of the no-load and on-load windings voltage of PMSG is proposed based on tooth flux method. This method takes the actual shape of poles and slots and the non-linearity of iron and permanent magnetic material into account. The results of computation and experiments on a PMSG show that tooth flux method is accurate. By use of this method, the values and waveforms of winding voltage for PMSG can be calculated accurately and quickly which can be effectively used to study the external characteristics of PM electrical machine.
