DC ELECTRIC MOTOR WITH PARTIAL BACK EMF Russian patent published in 2021 - IPC H02K23/04 H02K29/08 H02K16/02 H02K9/06 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, low voltage direct current electric motors, and can be used as a drive for any technical means. The electric motor has partial back emf due to its design, consisting of two armatures longitudinally offset along the shaft from each other, as well as electromagnets mounted on the stator opposite the armatures. The windings of the stator and armature electromagnets are not crossed by the magnetic poles and are parallel to each other. The stator electromagnets are included in operation when aligned with the poles of the armatures. On the gratings, in front of the anchors, graphite brushes are installed in isolation, and they are adjoined to the slip rings, isolated on the armatures. The shaft rests on rolling bearings located in the bearing assemblies of the stator end caps, and fans are fixed at its opposite ends. A circuit of transistors, diodes, Hall sensors and resistors ensures the operation of the electric motor. The electric motor is powered from the network through a current rectifier, and the accumulator provides the operation of the entire electronic circuit.

EFFECT: providing ability to work at low voltage by reducing the back emf.
