Abstract
Finite element analysis is used to obtain the non-linear variation of axis and cross-axis flux-linkages for a dq model of an interior magnet , brushless DC motor (BLDC). The model is used to compare competing de signs of the conventional form of BLDC with designs of a novel type th at has q-axis fur barriers. It is shown that the flux-barrier motor wi ll give (i) equal rated performance, and (ii) better over-rating perfo rmance.
