Described herein is an axial-flux electric motor, comprising: a stator (7) made of ferromagnetic material, which supports a plurality of windings (9) set at angular distances apart from one another about an axis of rotation (11) of the motor; at least one rotor (13) facing the stator (7) and provided with a plurality of permanent magnets (15), set at angular distances apart from one another and arranged approximately on a plane perpendicular to the axis of rotation (11); and a cooling system (20) comprising an annular tubular metal body (22) coupled to the stator (7) and provided with at least one system for circulation of a fluid inside the body itself.
The circulation system comprises a tube (30) with circular cross section with which a coil is made comprising three or four turns that extend inside the body (22) and are completely englobed in the metal material of which the body (22) itself is made.
