WINDING OF THREE-PHASE LINEAR INDUCTION PUMP Russian patent published in 1994 - IPC

FIELD: MHD equipment. SUBSTANCE: winding includes five pole pitches, each embracing three phase zones A, Z, B or X, C, Y. Each phase zone has two coils. Middle poles have permanent number of turns and extreme poles have reduced number of turns. Coil groups of phase zones by extreme pole pitches are connected in series with coil groups of phase zones of middle pole pitches. In this case there is same number of turns in parallel branches of all places and consequently consumed current is uniformly distributed by parallel branches which results in rise of developed pressure and efficiency. EFFECT: rise of developed pressure and efficiency. 3 dwg
