ELECTRICAL MACHINE ROTOR Russian patent published in 2004 - IPC

Abstract RU 2223585 C1

FIELD: electromechanical engineering. SUBSTANCE: rotor has alternating magnetic and nonmagnetic disks provided with openings to receive permanent magnets. Magnetic disks have slits in center of partitions between openings to form nonmagnetic gaps between permanent magnets with pole shoes. Jumpers formed between pole shoes and yoke function as holding members locking entire structure at high speed. Integration of yoke and pole shoes in the form of alternating magnetic and nonmagnetic plates with openings yields very good results. EFFECT: enhanced reliability at simple design and high manufacturability. 4 cl, 4 dwg
