DIRECT-CURRENT ELECTRIC MACHINE Russian patent published in 2020 - IPC H02K25/00 H02K1/24 H02K1/12 H02K19/20 

FIELD: electrical engineering.

SUBSTANCE: direct-current electric machine (DCM) comprises annular-type armature winding. Armature magnet core is made of laminated packs of laminated steel closed on outer diameter by external magnetic conductor. Inductor magnetic core is made of the laminated steel profiled annular packages, shifted relative to each other by the one pulse electric angle, equal to the quotient of the one pulse width division by the inductor packages number, and separated by annular non-magnetic gaps. Inductor winding generates the same polarity magnetic field. Air gap is made with periodic varying value on the length of each pole division according to the law of change of magnetic induction, providing for formation of unipolar pulses of alternating electromotive force in each pole division in armature winding. External magnetic conductor of the inductor is rod-shaped with envelopments fastening the stator core. Anchor core is divided into zones of direct and inverse pulses of electromotive force related to zones of pairwise packets of direct and reverse pulses of magnetic conductor of rotor.

EFFECT: technical result consists in improvement of mass-dimensional characteristics and simplification of design.
