3-D FINITE-ELEMENT ANALYSIS OF PERMANENT-MAGNET MOTOR EXCITED FROM SQUARE PULSE VOLTAGE-SOURCE

This paper describes a new method for the 3-D computation of the perma nent-magnet motor excited from the voltage source. The method has adva ntages that the 3-D mesh as well as the driving electric circuit is ch anged automatically according to the movement of armature. Our method is applied to the rotatning analysis of the IEEJ model excited from th e square pulse voltage source. The results calculated by the 3-d analy sis are compared with the results by the 2-D analysis. The validity of the new method is confirmed by the experiments.
