Document Type and Number:
WIPO Patent Application WO/2010/013501
Kind Code:
A1
Abstract:
Provided is a cylindrical iron core, in which a gap in the whole section of a stationary electromagnetic induction-type circular core of a transformer or a reactor can be reduced and limiting iron loss due to leakage flux on the outer circumferential surface can be suppressed. The cylindrical iron core comprises a plurality of core blocks (2) formed by concentrically laminating cylindrical core elements (2A, 2B, 2C) which are formed by laminating a plurality of magnetic steel plates (21), each of which is provided with a curved portion (211) having a curved section in the width direction, while shifting from each other in the width direction.
