Abstract
A rotor for an electric motor comprising a crankshaft extending along an axis (X-X) coinciding with an axis of rotation of the crankshaft, and at least one steel plate having slots for housing magnets. The steel plate includes a central seat, keyed to an outer side wall of the crankshaft according to an interference coupling, wherein the steel plate is coupled to the crankshaft at the central seat by a first tooth obtained on the steel plate, which projects towards the associated crankshaft and a first radial seat, obtained on the outer side wall of the crankshaft. The first radial seat has an isosceles trapezium cross-section delimited laterally by a pair of oblique sides converging towards the axis of rotation. The first tooth has a 'V' cross-section with a pair of curvilinear side walls, suitable for interfacing against the oblique sides of the first radial seat.
