ELECTROMAGNETIC PUMP Russian patent published in 2013 - IPC H02K44/02 

FIELD: electrical engineering.

SUBSTANCE: pump consists of transformer where short-circuited secondary winding is made as closed loop of pumped medium covering transformer core and having areas for medium input and output. Along the loop perimeter there are alternating electromagnets creating magnetic field oriented perpendicular towards currents in the loop. The primary winding of the transformer and magnet windings are supplied by one AC mains. Supply circuit of transformer or electromagnet windings includes phase-shifting devices that ensure phase shift of transformer and magnet fluxes at the angle of 90° or close to it. Capacitors connected in series with electromagnet windings can be used as such phase-shifting devices; and capacitors and electromagnet windings have the same reactive impedance at frequency of the supply mains.

EFFECT: higher operating efficiency.
