DC ELECTRIC MACHINE Russian patent published in 2018 - IPC H02K19/20 H02K1/12 

FIELD: electrical equipment.

SUBSTANCE: invention relates to the electrical equipment, namely, to the DC electric machines. Electric machine comprises the annular type armature winding, and the armature magnetic circuit consists of the laminated steel annular packages, along the external diameter closed by the external magnetic circuit. 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 a periodic value along the each pole division length according to the magnetic induction variation law, which provides for the one-variable EMF unipolar pulses induction in each pole division in the armature winding. Longitudinal non-magnetic inserts execution in the form of saturating magnetic sections allows to improve the machine mass and dimension characteristics and increase its reliability.

EFFECT: technical result consists in development of the unipolar, unidirectional pulses, excluding the inverse EMF component at each pole division.
