Description

<p>This paper presents a new type of axial gap motor, called the flux-modulating hybrid field motor (FHM). For flux modulation, the FHM has rotor iron pieces sandwiched between two stators, the armature and field poles. The field poles comprise permanent magnets and electromagnets, and the magnetic flux of the electromagnets can be adjusted by changing the field current. To validate the principle of this FHM, a 0.8-kW prototype machine was fabricated, and the basic characteristics of the prototype machine were investigated through experiments and three-dimensional finite element analysis. The results show that the torque can be varied in a wider range by changing the armature current vector and field current.</p>
