SPLIT SKEWED AND STACKED CORE AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To make the easy winding work or the insertion work of formed coils or permanent magnets or the like by skewing a yoke of a core for an rotating electric machine and magnetic pole teeth to improve electromagnetic characteristics between a stator and a rotor and by splitting the yoke and the magnetic pole teeth by the unit of the magnetic pole tooth. SOLUTION: The split skewed and stacked core is constituted of the yoke 10Y of a partially circular shape having dimensions corresponding to a shape obtained by dividing the cylindrical yoke of the stacked core of total stacked core element pieces 10-1, 10-2, to 10-nby the number of magnetic pole teeth, and a magnetic pole tooth 10T that protrudes from the side 10U of its front side of each yoke 10Y and that protrudes at an angle that differs by a unit angle obtained by dividing the skew angle by the number stacked pieces. These total stacked core element pieces 10-1, 10-2, to 10-nare stacked one by one in the order of protruding angles of the magnetic pole teeth 10T that increase by the unit angle from a skew starting point to an end point.
