LIKE-POLE INDUCTOR GENERATOR WITH BUILT-IN POWER RECTIFIER Russian patent published in 1998 - IPC

FIELD: electrical engineering and electromechanical engineering; off-line power supplies for DC arc welding, wind-electric generators, or plants where two voltage levels are required. SUBSTANCE: generator has two stator stacks carrying multiphase armature winding and diamagnetic ring with air intake ports provided between them, as well as two rotor stacks press-fitted onto common shaft concentrically to stator stacks. Each stator winding is connected to respective rectifier unit. EFFECT: provision for organizing separate magnetic system and producing two voltage levels or higher current at generator output for arc welding. 2 dwg
