Abstract

1. Electric machine, axially ventilated on both sides and having a salient-pole rotor, in which the pole shanks (3) carry pole coils (5) and in each interpolar gap at least one coolant-distributing body (12) is arranged, which extends in the axial direction, the side faces (13) of which are at a distance from the pole coils (5), forming gaps (14), characterised in that the coolant-distributing body (12) is constructed to be tubular and is open at its front end, that in the part (12'), facing the central body (1) of the rotor, of the coolant-distributing body (12) at least one opening (16, 17) is provided, that the side faces (13) of the tubular coolant-distributing body (12) are parallel to the entire side faces of the pole coils (5) to be cooled, that the gaseous coolant flows axially into the coolant-distributing body (12), that in the interior of the coolant-distributing body (12) it is guided, after deflection in the direction of the central body (1) of the rotor, through the opening (17, 18) into the space between the coolant-distributing body (12) and the central body (1) of the rotor, that, after being deflected again, it is guided into the said gaps (14) to the pole coils (5) and that the tubular coolant-distributing body (12) is joined to the central body (1) of the rotor and kept at a distance from the latter by means of retaining bolts (22).
