MAGNETOELECTRIC MACHINE Russian patent published in 2009 - IPC H02K21/12 H02K23/52 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, particularly to synchronous machines with permanent-magnet excitation. The windings of each generator terminals are connected to two neighbouring windings of motor terminals. Electrical currents with the same direction arising in turns in active wires of each generator terminal flow in winding turns of neighbouring motor terminals, where they generate powerful local magnetic field pulses due to high magnetic permeability of their cores. These magnetic field pulses interact with magnetic field created by permanent magnets of an inductor, which results in acceleration of the rotor of the machine. After one permanent magnet with one pole comes out of the zone of the generator terminal, and the other two from the zone of motor terminals, other permanent magnets of the inductor enter these zones, though with an opposite pole. This gives rise to emf of opposite polarity in active wires of the generator terminal. In the same windings of motor terminals, currents with different direction flow, changing polarity of the latter. The direction of currents changes four times in one revolution, during which there is mutual transformation of electrical, magnetic and mechanical energy and interaction of magnetic field pulses of the stator with magnetic field of permanent magnets of the inductor, which leads to stable operation of the magnetoelectric machine.

EFFECT: easier regulation of speed and starting, increased efficiency due to presence of elements of the generator and motor at the same time, which interact with each other.
