Abstract

An axial flux machine (AFM) includes a rotor rotatably disposed between a pair of fixed stators. The rotor and the stators are formed of tape-wound laminated cores of ferromagnetic material. In addition, the rotor includes multiple layers of angled magnets that circumscribe the rotor. Such configuration enables the axial flux machine to achieve a high airgap flux density while achieving a high saliency ratio and lowered cogging torque as compared to current generation AFMs.
