FIELD: electrical engineering. SUBSTANCE: generator is permanent-magnet machine built up of internal and external blocks of stators and rotors. Block of internal and external rotors has commutators with removable shells for replacing their brushes and springs installed in seats of block of internal and external stators for setting rotor block in rotary motion. Ends of stator block carry pin-mounted rollers meant to maintain gaps of fields of magnetic force. Generator has vacuum casing ; longitudinal cavities are provided under rotor and stator windings in respective blocks for cooling these windings by creating vacuum in cavities. EFFECT: improved output power of generator, facilitated replacement of commutator brushes and springs, improved cooling conditions for generator windings. 2 cl, 6 dwg
