Abstract
A rotor of an electric motor has a carrier structure including a disc portion to which is centrally connected a shaft, and the periphery of which is joined to an essentially cylindrical annular skirt portion which in use extends coaxially around the stator. The disc portion has a plurality of slots between which there is defined a corresponding plurality of spokes. At least some of the spokes have, in a circumferential direction, a transverse cross-section shaped in a manner to induce, at least when the rotor rotates in one direction, an at least approximately axial air flow through corresponding slots.
