<p>PROBLEM TO BE SOLVED: To solve the following problem: a gap is made between electrical steel plates when a plurality of electrical steel plates are stacked in such a manner that caulking protrusions of the electrical steel plates overlap each other.SOLUTION: In a rotor formed by stacking a plurality of electrical steel plates with through-holes or protrusions, the electrical steel plates are stacked in such a manner that the protrusions of the electrical steel plates do not overlap each other in a stacking direction and that the protrusion of the one electrical steel plate is fitted into the through-hole of at least another electrical steel plate.</p> |
