ELECTRICAL MACHINE ROTOR MANUFACTURING METHOD Russian patent published in 2001 - IPC

Abstract RU 2168829 C1

FIELD: instrumentation and electrical engineering; high-speed electrical machines. SUBSTANCE: method involves manufacture of hollow shaft with shaft extension and first cap with shank coupled with shaft, as well as insertion of rod-shaped permanent magnet into shaft hollow; permanent-magnet rod is manufactured from magnetized powder by pressing it. Hollow shaft with shaft extension is made in the form of thin- walled bushing, then second cap with pin is manufactured, whereupon they are joined together. EFFECT: facilitated manufacture, reduced material input, enhanced torque transmitted by rotor. 2 cl, 7 dwg
