Abstract
A circular electromagnetic flow coupler comprises a circular flow path, conductive partition walls which divide the circular flow path into generator side flow paths and pump side flow paths in the circumferential direction thereof, insulators for insulating the inside and outside of the flow paths, and magnetic poles for generating a magnetic field in the radial direction of the circular flow path. The insulators are provided with openings so that they are not damaged when pressure is exerted thereto.
