ROTOR FOR ELECTRIC MACHINE AND ELECTRIC MACHINE

摘要

FIELD: electricity.SUBSTANCE: invention is related to rotor for electric machine. Rotor (301) for electric machine (201) comprises pole core (303), which has cooled and magnetisable rotor section (313) of superconductive material. At that rotor section (313) has rotationally symmetrical geometry. Pole core (303) is made as a cylinder while rotor section (313) is placed in circumferential direction at outer surface (309) of the cylinder. At that the cylinder is made as a hollow cylinder (305) for input of cooling fluid into inner space (307) of the hollow cylinder (305).EFFECT: improved cooling efficiency for the rotor.11 cl, 3 dwg
