Rotors for electric rotary machines

Abstract

The present invention provides a rotor for a rotary electric machine, the rotor extending along a longitudinal axis and comprising: at least two poles defining between them an inter-pole space; and windings of electrical conductors wound around the poles, said windings including straight portions extending along the longitudinal axis of the rotor; at least one pole of the rotor, and in particular each pole of the rotor, including a spacer placed along at least a fraction of the straight portion between at least two conductor groups of the windings so as to form at least one cooling channel between the two conductor groups, enabling a cooling fluid to flow longitudinally and/or transversely within the windings, the spacer including at least one spacer element presenting a cross-section that is hollow, defining the cooling channel at least in part.
