摘要

In a rotating machine, a plurality of laminated electromagnetic steel sheets constitutes at least one of a stator and a rotor and a plurality of permanent joining portions to unit each of the laminated electromagnetic steel sheets to form a corresponding one of the stator and the rotor, the plurality of permanent joining portions being set to be located at positions at which an integration value of a magnetic flux density with respect to a plane enclosed with the permanent joining portions is always zeroed.
