ONE-PHASED ELECTRIC ENGINE BASED ON ALTERNATING CURRENT Russian patent published in 2006 - IPC H02K25/00 H02K19/06 

FIELD: electric engineering, in particular, engineering of noncontact electric engines, meant for use in industry as electric drives for mechanisms of large and average power, powered by one-phased alternating current network, transforming electric energy to mechanical energy, for example, at electrified railroads in electric trains, electric transportation means.

SUBSTANCE: one-phased electric engine based on alternating current contains immovable cylinder-shaped portion in form of stator, within hollow of which shaft is positioned, mounted on bearings of end lids, with rotor held thereon, packets of insulated electro-technical steel sheets, while on internal surface of stator evenly around its circle contour two rows of electromagnetic poles are held, mounted inclined at a tangent to rotor circle in opposite direction of its rotation, while rows of electromagnetic poles are shifted relatively to each other along stator circle for half of step, equal to half the distance between electromagnetic poles, also, engine is provided with control disk, held on shaft of rotor, along circle of which in its grooves packets of insulated electro-technical steel sheets are evenly held, entering recess of control transformers, number of packets corresponding to amount of active parts of rotor and number of electromagnetic poles of stator, while packets on control disk are positioned symmetrically to active parts of rotor with possibility of their synchronous rotation.

EFFECT: simplified constructions of engine with simultaneous increase of efficiency coefficient and increase of spinning momentum.
