In a hydrogen cooled, slotless rotor 1, the conductors 6 are mounted between axially extending fences (11) mounted in grooves (12) in the rotor (Fig. 3 not shown), with twelve conductors between each pair of fences (11). Each conductor has two halves with a mi-elliptical groove which when the halves are fixed together provide cooling ducts. The conductors are insulated from the steel rotor body 1 by an inrt (17, Fig. 3) and from each other by radial and peripheral partitions (15, 16). The cooling ducts through the conductors connect with ducts 22 in the rotor which themlves connect to axial ducts in the end-winding support (8, Fig. 1 not shown). Annular fibrereinforced resin rings 25 are prestresd by the inflation of bags 27 with synthetic resin at high pressure this then being cured at high temperature. Axial movement of the rings is prevented by T-shaped supports 26 of steel or phosphorbronze which may be interconnected to form a damping winding. As an alternative, the rings 25 are prestresd by a hydraulic device (Fig. 7 not shown) and then slipped overthe conductors. The conductors may be coated on the periphery with PTFE or molybdenum disulphide to enable expansion under high temperature working.

In an alternative embodiment (Figs. 8, 9 not shown) a water cooled rotor is described, the annular members being similar to the previous embodiment. The conductors, however, are of hollow rectangular cross-ction, the fences are tapered and no intermediate supports 26 are necessary. The machine end windings are cured by the method disclod in Specification 1,474,972.
