SELF-SUSTAINED MOTOR-GENERATOR PLANT Russian patent published in 1995 - IPC

FIELD: vehicle traction plants, self-sustained three-phase stand-by power source. SUBSTANCE: synchronous generator 2 is used in power plant, and DC motor of drive mechanism is mounted on generator shaft. Mounted on shaft of additional dynamoelectric set is flywheel 16 and induction motor 14 with phase-wound rotor connected through rectifier to armature circuit of motor 1 and through contacts 12 and 13 to terminals of storage batteries used to supply motor 1. Batteries can be charged through rectifier 9 by synchronous generator 2 on shaft of which flywheel 16 is mounted. EFFECT: increased efficiency of plant and its service life owing to use of kinetic energy of rotating masses of electric machines and flywheels. 1 dwg
