            Abstract : 
A study for the enhancement of effective flux of PM machines using flux guides is presented. An intrinsic demagnetization curve that considers the leakage flux is introduced. On the basis of a higher effective flux the stator winding can be more compact; consequently, a lighter stator and a higher efficiency permanent magnet (PM) machine can be obtained
