Title:
ELECTROMAGNETIC FLOW COUPLER
Document Type and Number:
Japanese Patent JPS63213465
Kind Code:
A
Abstract:

PURPOSE: To suppress counter-electromotive voltage and eddy current, by setting a reactive current suppressing plate in the passage of one side system corresponding to an external magnetic pole end section in the flowing direction of conductive fluid.

CONSTITUTION: In a ring-formed space set between a central circular-column- formed internal magnetic pole 1 and a comb-formed external magnetic pole 2 set radially on the outer periphery, a ring-formed passage consisting of an internal pipe 5 and an external pipe 6 is formed. The passage is separated from by a partition wall 9 so that a generator side passage 7 and a pump side passage 8 may be alternately arranged in the circumferential direction, and at a comb-formed recessed section, a ring-formed exciting coil 10 is set. In the one side system passage 8 corresponding to an external magnetic pole end section in the flowing direction of conductive fluid, a reactive current suppressing plate 11 for suppressing reactive current generated at the external magnetic pole end section is provided using this electromagnetic flow coupler. Then, the reactive current is suppressed, and efficiency is improved.
