Abstract

PURPOSE: To facilitate installation of a shield plate for reducing air loss between the salient-pole magnetic poles by forming thereof in a shape of a wave swelling along the rotating shaft.
CONSTITUTION: A core head 14 in a salient field 11 is provided with a groove 15 into which a shield plate 21 formed in a shape of a wave swelling along the rotating shaft is fitted to reduce air loss induced by the rotation of the rotor. With such an arrangement, an elastic effect of the wave form allows the shield plate 21 to be elastically engaged with the groove thus facilitating installation without play and eliminating mount members. The wave-shaped section provides a higher mechanical strength while a higher electric resistance is obtainable when a conductive metal is used for the shield plate
