Abstract
There is provided a method for measuring a laminated iron core. The method includes preparing a laminated iron core in which two or more kinds of metal plates with different shapes are laminated and a deformed part is formed inside a hole continuing in a lamination direction of the laminated iron core, acquiring a surface profile data indicating a surface shape of the deformed part through an inlet of the hole by a non-contact sensor located in an outside of the hole, and calculating a length from the inlet of the hole to the deformed part in the lamination direction by a calculator based on the surface profile data.
