AXIAL-FLUX ELECTRIC MACHINE WITH WINDING ROTOR AND METHOD FOR THE PRODUCTION THEREOF

摘要

An axial-flux electric machine with a winding rotor comprises a stator section (PS) and a rotor section (PR), both developing around and axis (X). The rotor section (PR) comprises a rotor (1), which, in turn, comprises a toroidal rotor core (2) made of a ferromagnetic material and a plurality of windings (3) and of teeth (4), which are angularly distributed on the rotor core (2) in an alternated configuration. The teeth have, on at least one lateral surface of theirs, a shaped profile defining at least one holding surface (12), which is such as to cooperate with a resin matrix, which is suited to steadily lock the teeth (4) on the rotor core (2).
