UNIPOLAR SET Russian patent published in 1998 - IPC

FIELD: electrical engineering; chemical-to-electromechanical energy converters; power engineering for transport. SUBSTANCE: four unlike-polarity multiple-coil field windings of thermopile electrodes are placed between poles on stator and rotor magnetic cores so that electric current is uniformly distributed among sections of armature conductors on intermediate poles of particular stator and rotor for interacting with crossing magnetic fields built up by these windings and for producing unidirectional electromagnetic forces setting rotor in rotary motion. Such closure of two thermopiles through armature conductors provides for dispensing with moving current collectors whose function is performed by surface contacts of unlike-polarity coil electrodes of thermopiles moving through electrolyte which greatly speeds up electrochemical reaction. Stator compensating conductors are also used as armature for producing additional electromagnetic field setting rotor in rotary motion as their currents interact with magnetic fields around rotor windings. Turn-to-turn insulation (coiled edges) elevated above rotor winding surface used for electrolyte pumping makes it possible to dispense with separate pumping unit. EFFECT: improved specific power characteristics of set; facilitated thermostatic control of electrochemical reaction; improved environmental friendliness, reduced noise. 3 dwg
