SALIENT POLE ROTOR OF SYNCHRONOUS ELECTRIC MACHINE Russian patent published in 1994 - IPC

FIELD: electric machine engineering. SUBSTANCE: poles of salient pole rotor of electric machine are manufactured partially laminated in direction parallel to rotation axis of machine with positioning of lamination stack 7 between pressure plates 3. Air-and-insulation joints exist between stacks and yoke. Radial clearances 10 (with nonmagnetic spacers) are made in rotor yoke under centers of poles. Shaft is produced from nonmagnetic material. Adjacent pressure plates of neighboring poles together with sector 5 of yoke are fabricated in the form of integral solid structure. Solid tips 9 of pressure plates are fastened to cores of the latter by bolts. EFFECT: increased reliability, facilitated manufacture. 1 dwg
