Abstract:
1. An intelligent-cascaded synchronous electric motor-generator tandems of cumulative compound excitation comprising at least a synchronous electric motor-generator tandem with a saddle chassis, a storage battery cluster connected to the electric motor-generator tandem, an autotransformer connected to the electric generator, at least a ring geared flywheel connected to a shaft of the motor-generator tandem, and a starting booster of DC motor with a mounting rack and a pinion coupled to the saddle chassis of the motor-generator tandem, wherein: each said synchronous electric motor-generator tandem comprises at least a pair of electric motor and electric generator having a common stator with a frame and a common rotor shaft having an armature with a motor winding for the motor and a generator winding interlaced respectively; both of said motor winding and generator winding configured to rotate in same direction coincidentally on the same common rotor shaft; each said electric motor has a stator pole coil winding and a rotor armature coil winding while said electric generator has a stator pole coil winding and a rotor armature coil winding respectively such that the arrangement of each winding in respective slots of a core of the rotor shaft armature and the common stator are grouped and interlaced in right facing set and left facing set to be specially configured by versatile combinations; said storage battery cluster configured to provide a DC power source to general loads in addition to supply starting current to the electric motor and working DC power supply to external loads, and configured to serve as a DC power reservoir to be recharged by DC output of the electric generator in the synchronous electric motor-generator tandem; and said autotransformer connected to output brush terminals of the electric generator of the MG tandem configured to regulate AC voltage output from the electric generator via multiple taps thereon in step-up or step-down manner for supplying various AC voltages to different external loads.
