Abstract

The performance analysis of a permanent-magnet synchronous generator with surface-inset rotor feeding a rectifier load is described. The time-stepping, coupled-circuit, two-dimensional finite-element method enables the instantaneous values of field and circuit variables to be solved simultaneously. Useful generator information, such as the air gap flux distribution, voltage and current waveforms, steady-steady performance and short circuit transients can thus be obtained. Good agreement between the computed and experimental results has been obtained for a 2.5 kVA prototype generator.
