Investigate to variable flux motor expand the range of high efficiency operation has been actively conducted in recent years. Therefore, in this study, a variable field PM motor with a field winding in the stator was proposed. Since the field winding acts as an induction machine, the proposed motor controls the air-gap magnetic field directly. The field winding also　contributes to reducing the induced electromotive force, which can be expected to improve the field weakening capability and the operation range. This paper shows the basic characteristics of the proposed motor by 3D-FEA result.
