INDUCTOR OF THREE-PHASE CYLINDRICAL LINE INDUCTION PUMP OR MAGNETOHYDRODYNAMIC MACHINE (VERSIONS) Russian patent published in 2009 - IPC H02K44/06 H02K44/08 

FIELD: electricity.

SUBSTANCE: invention relates to the sphere of electrical and magnetohydrodynamic engineering and is to be find application in induction electromagnetic pumps for pumpover of liquid-metal coolants in fast breeder reactors, in chemical industry and metallurgy, as well as in magnetohydrodynamic machines and line induction motors. The invention concept is as follows: under the first invention implementation version the three-phase winding of the proposed inductor is designed to have an even number of poles (at least two) with the number of pole/phase slots q = 2. The winding in laid in slots of the external magnetic circuit, the number of turns in coils fixed, and has at least two parallel paths. The coils positioned at the second phase band at the first pole pitch input are connected in parallel with the other coils at other pole pitch phase bands connected in series. Under the second invention implementation version the three-phase winding of the proposed inductor is designed to have an even number of poles, the number of turns in coils fixed, and has at least two parallel paths with the number of pole/phase slots q = 3. In this inductor excitation winding two coils positioned at the second phase band are interconnected in parallel at the first pole pitch input and connected to the third coil in series. All the other coils at other pole pitch phase bands are connected in series.

EFFECT: reduction of power supply current phase asymmetry and increase of the developed pressure and performance of the induction pump or magnetohydrodynamic machine.
