| Abstract |
This work deals with the analysis of the high harmonic contents on the PM flux linkage and induced back emf of a PM machine at no load and with delta connected winding topology. The skewing effect on these unwanted high harmonics is investigated for a continuously skewed and a discrete skewed rotor topology. The FE results show that the PM flux linkage of the studied machine contains high harmonics of odd order. When the phase windings are connected in delta the PM flux linkage and resulting induced back emf contains high harmonics of order 3rd and 9th. Further, the analysis performed here show that using skewed rotor topology these high harmonics clearly can be reduced. |
