Computation of Saturated Permanent-Magnet AC Motor Performance by Means of Magnetic Circuits

A digital computer evaluation of transient states in a permanent-magnet (PM) machine by means of the flux tubes method is described. The influence of initial rotor phaseshift on transient torque peaks, as well as the influence of saturation on current waveforms, is shown. Several computer runs are c...

Beschreibung
Zusammenfassung:	A digital computer evaluation of transient states in a permanent-magnet (PM) machine by means of the flux tubes method is described. The influence of initial rotor phaseshift on transient torque peaks, as well as the influence of saturation on current waveforms, is shown. Several computer runs are carried out to illustrate the applicability of the flux tubes method for computation of PM machine performance.
