LINEAR CYLINDRICAL INDUCTION PUMP Russian patent published in 2006 - IPC H02K44/06 H02K41/25 

FIELD: electrical engineering; nuclear power engineering, chemistry, metallurgy, linear induction motors.

SUBSTANCE: proposed pump that can be used for pumping liquid metals has external and internal magnetic circuits with input and output shorting-out sections. External magnetic circuit slots accommodate three-phase field winding with phase bands equally disposed on pole pairs. Shorting-out section at magnetic circuit output has extended length compared with that at input. Length of output shorting-out section amounts to minimum phase band length and maximum pole pitch value.

EFFECT: reduced double-frequency pressure fluctuations in power supply, enhanced efficiency and developed pressure.
