Abstract: FIELD: electrical machines. SUBSTANCE: double-stack electrical machine has stator built up of two stacks 10,11 with teeth on outer surface, solid core 7, and disks 8,9. Stator is placed inside rotor 2. Ring-type field winding 17 is wound under armature winding 16 and partially in annular drillings of solid disks. Stacks are spaced apart to meet condition of minimal mass of windings which is 0.15-0.9 of armature turn length multiplied by ratio of stacks dissipation flux to core flux and by ratio of field winding and armature winding masses. Laminations of both stacks are compressed through nonmagnetic spacer 13 placed between them. Electromechanical conversion takes place due to pulsation of magnetic flux in wound teeth of stacks. Machine is cooled down due to dragging air flow in diffusion sections of air intakes mounted on rotor. Joule heat of field windings is transferred to core iron. EFFECT: improved design. 3 cl, 4 dwg
