Abstract: According to one embodiment, a stator includes spacing strips disposed to be interposed in the electromagnetic steel plates for each predetermined set of plates of the electromagnetic steel plates, each of the spacing strips extending in a radial direction of the stator iron core to form ventilation ducts, a spacing strip attachment plate which is disposed between the spacing strips and the set of plates of the electromagnetic steel plates to fix the spacing strips, and an insulating layer which covers the entirety of the spacing strip attachment plate and the spacing strips fixed to the spacing strip attachment plate.

Abstract: According to an embodiment, an inspection device comprises a moving body that includes; a moving main body which moves in contact with a first structure; arms attached to the moving main body; an arm driver to drive the arms; and a detector attached to the moving main body or the arms to inspect the second structure. The arms each can selectively take a pressed position and a detached position. When the moving body is moved, at least one of the arms are in the pressed position and pressed to the second structure, and the moving body is supported by the first and second structures.

Abstract: According to an embodiment, an inspection system comprises: a moving body including a moving main body movable along a structure; a detector attached to the moving main body; a shape information storage unit for storing shape information indicating shape and size of the structure; an inspection location information storage unit for storing information of inspection locations to be inspected; an inspection item information storage unit for storing information of inspection items to be inspected; a moving body location detecting unit for detecting moving body location information indicating location of the moving body; a moving control unit for controlling movement of the moving body; and an inspection control unit for inspection.
