WINDING OF THREE-PHASE LINEAR INDUCTION PUMP Russian patent published in 2008 - IPC H02K44/06 H02K41/02 

FIELD: electrical engineering.

SUBSTANCE: in winding of three-phase linear induction pump that contains three poles and two parallel branches formed by serial connection of coil groups in phase zones, which have permanent number of turns in coils, according to this invention, the first parallel branch is formed by means of serial connection of coil groups is formed by means of serial connection of coil groups in the first pole pitch with half of coil groups at the second pole pitch, at that coils of coil groups of the second phase zone located at the inlet at the first pole pitch, are connected parallel to each other, and the second parallel branch is formed by means of serial connection of coil groups of the third pole pitch with the second half of coil groups of the second pole pitch.

EFFECT: reduction of unbalance of supply currents; increase of pressure; increase of pumps efficiency factor.
