  • Patent number: 5036238
    Abstract: A rotor of a salient-pole type rotary machine is disclosed in which field coils are held by a coil brace disposed between adjacent magnetic poles. In addition to the coil brace, a holder provided with an elastic member is also disposed between the magnetic poles, and another elastic member is disposed between the coil brace and the said holder, whereby the said two elastic members are utilized for the fixing of the field coils and for the pressing force of the coil brace. And the whole of the coil holding mechanism is separated from a spider. This construction permits the field coils to be held in place without any great change in the holding force under any dimensional change.
