ROTOR Russian patent published in 1999 - IPC

FIELD: electrical engineering. SUBSTANCE: rotor specially designed for high-speed motor-generator sets is made of fiber-reinforced plastic material including material with magnetic filler; fiber-reinforced plastic material forms multilayer cylindrical section of rotor and material with magnetic filler is placed inside at least one layer and between layers. Rotor manufacturing process involves winding of initial layer of resin-impregnated fibers onto arbor and at least one intermediate layer containing resin- impregnated fibers to form gaps between the latter. Mixture of material with magnetic filler and polymeric matrix material is placed in mentioned gaps. Then external layer of resin-impregnated fibers is wound around intermediate layer and magnetic field is applied to level off material with magnetic filler according to desired orientation while resin is in liquid state before and in the course of gelation process. For final procedure, resin is cured and magnetic material is magnetized. EFFECT: improved operation of electrical machines at high rotor speeds. 8 cl, 4 dwg
