ELECTRICAL MACHINE Russian patent published in 1998 - IPC

FIELD: electrical and electromechanical engineering. SUBSTANCE: machine has stator with radial ducts 3, rotor 9 inside enclosure 12; novelty is that at least on one side of core-and-winding assembly of rotor there is end disk 13 that forms, together with pressure disks 14, slit 15 for admitting cooling gas to axial ducts 16. Disk 13 is secured to respective end portion of enclosure 12 and slit 15 is arranged on smaller diameter of rotor as compared to arrangement of outlet ports of cooling ducts.
