PCT No. PCT/SE87/00449 Sec. 371 Date Apr. 4, 1989 Sec. 102(e) Date Apr. 4, 1989 PCT Filed Oct. 6, 1987 PCT Pub. No. WO88/02570 PCT Pub. Date Apr. 7, 1988.A machine for winding a rotor core for a rotating electrical machine, the rotor core having axially extending winding slots and to be provided with a winding comprising a number of coils corresponding to the number of winding slots, includes two mutually similar winding devices (2, 3) arranged coaxially opposite another. The winding devices can be brought together and moved apart in the axial direction and each device includes a wire guide ring (16) having an inner diameter larger than the outer diameter of the rotor core (13) and provided in its surface thereof facing the other winding device with radially extending wire guide grooves (17) corresponding to the winding slots of the rotor core. The inner surface of the ring (16) has provided thereon, opposite each guide groove (17), a radially and inwardly projecting lug (18) with radial extension exceeding the clearance between the inner surface of the ring (16) and the outer surface of the rotor core (13). Each winding device (2, 3) also includes a rotor guide sleeve (19) arranged co-axially in relation to the wire guide ring (16) and rotatable, but not axially movable, in relation to the wire guide ring (16). The rotor guide sleeve (19) has a cylindrical inner surface having a diameter slightly exceeding the outer diameter of the rotor core (13) and provided with axially extending ribs (22) which correspond to and can engage the winding slots on the rotor core. |
