Claims (1)
複数の前記打ち抜き部材を積層して積層体を形成する第２の工程とを含み、
前記第１〜第Ｎの打ち抜き部材にはそれぞれ、前記第２の工程での積層時において互いに重なり合う位置に、凹状又は凸状を呈する複数の異形部が形成されており、
前記第ｋ（ｋは１〜Ｎの自然数）の打ち抜き部材の形状と前記第ｍ（ｍは１〜Ｎで且つｍ≠ｋを満たす自然数）の打ち抜き部材の形状とが相互に一致しないように、前記第ｋの打ち抜き部材における前記複数の異形部のうち少なくとも一つの異形部の形状又は配置が、前記第ｍの打ち抜き部材における前記複数の異形部のうち少なくとも一つの異形部の形状又は配置と異なっている、積層鉄心の製造方法。 In the position of the strip-shaped metal plate in the width direction to the parallel department first to N (N is a natural number of 2 or more), by punching the metal plate along the punching shape of the predetermined first through N, said first A first step of forming first to Nth punching members respectively corresponding to the first to Nth punching shapes;
And a second step of laminating a plurality of said punching members to form a laminated body,
In the first to Nth punching members, a plurality of deformed portions having a concave shape or a convex shape are formed at positions overlapping each other at the time of stacking in the second step,
The shape of the kth (k is a natural number of 1 to N) punching members and the shape of the mth (m is a natural number satisfying 1 to N and m ≠ k) punching members do not coincide with each other. The shape or arrangement of at least one deformed portion of the plurality of deformed portions in the kth punching member is different from the shape or arrangement of at least one deformed portion in the plurality of deformed portions of the mth punching member The method of manufacturing a laminated core.
