FREE-PHASE MAGNETIC CORE STATOR OF ELECTROMECHANICAL ENERGY CONVERTERS FROM AMORPHOUS IRON WITH MINIMUM INFLUENCE OF VORTEX CURRENTS (OPTIONS) Russian patent published in 2018 - IPC H02K1/12 H01F3/06 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used in electromechanical power converters of autonomous objects. Stator phase-free magnetic core of electromechanical energy converters of amorphous iron with minimal effect of eddy currents contains coil groups, mounted on the unpaired magnetic core of the stator, made in the form of a hollow cylinder, in the inner part of which a rotor is mounted. Hollow cylinder of the phase-free magnetic core stator is made of a twisted thin filament of amorphous iron, on the inner and outer walls of the same are mounted coil groups in the form of toroidal windings. In the second embodiment, the hollow cylinder of the phase-free magnetic core stator is comprised of three parts. Middle part is made of twisted their strips of amorphous iron, and the ends of the unrestricted magnetic core are made twisted from thin filaments of amorphous iron. Length of the end parts is equal to the depth of penetration of the magnetic flux emanating from the frontal parts.

EFFECT: increase of reliability, energy efficiency and minimization of heat emission of electromechanical energy converters, increase efficiency by 1–2 %, as well as reduction of losses in the magnetic circuit created by the fields of the frontal parts.
