Description
【発明の詳細な説明】 ［発明の背景〕 本発明は電気機械用ステータパックに関する。[Detailed description of the invention] [Background of the invention] The present invention relates to a stator pack for electrical machines.
従来のステータパックは、多角形形状を成す複数の鋼板

ある。A conventional stator pack is constructed by stacking a plurality of polygonal steel plates, and these steel plates are stacked alternately so that they do not overlap each other. A disadvantage of this conventional stator pack is that the inner arcuate portion of the steel plate is cut off, resulting in wasteful surplus, ie, scrap.
［発明の概要］

・とにより達成される。The object is a stator pack for an electrical machine consisting of laminated independent steel plates; comprising two similar rectangular parts having a height equal to the height of the stator pack; and the stator pack is constructed by stacking a plurality of semi-packs;
These semi-packs are each formed by making the front edges of the rectangular parts of a pair of the steel plates abut against each other; these semi-packs are also formed by shifting the steel plates in the rotational direction by an arbitrary angle that is an integral multiple of the angle between the status rods. This is achieved by being well-equipped.
本願に開示された電気機械用ステータパックの利点は、
標準的な帯鋼におけるステータシ一トの無駄が生じない
ブランク取りのために、この電磁鋼板の浪費が減少する
ことにある。The advantages of the electromechanical stator pack disclosed in this application are:
Due to the waste-free blanking of the stator sheet in standard steel strips, this waste of electrical steel sheet is reduced.
尚、無駄な円弧状のスクラップが生じないために、ロー
夕は他のブラ゛ンクから別に製造する。Incidentally, in order to avoid unnecessary arc-shaped scrap, the rotor is manufactured separately from other blanks.
