Static induction machine
By forming grooves on the main surface portions of a wound core but avoiding bent portions, the device achieves lower iron loss through controlled groove formation and depth, addressing the issue of magnetic flux leakage in conventional wound cores.

Abstract
To provide a stationary induction device having a wound core with reduced iron loss compared to conventional devices.SOLUTION: A stationary induction device has a wounded core configured from electromagnetic steel sheets. The laminated core includes a lap part where one end and the other end of an electromagnetic steel sheet are lap-joined, a bottom part that is a part opposing the lap part, a first arm part extending from one end of the bottom part to the lap part, and a second arm part extending from the other end of the bottom part to the lap part. The bottom part, the first arm part, and the second arm part each have a main surface part formed by a plane horizontal in the circumferential direction, which is a winding direction of the wound core. Grooves for subdividing magnetic domains are formed on the main surface part.SELECTED DRAWING: Figure 11
