Abstract
A method of manufacturing a stator core includes punching out core members from an electrical steel sheet in three rows arrangement side by side along a width direction of the electrical steel sheet. Each of the core members has connecting projections. The connecting projections project radially outward from an outer periphery of the core member. The punched out core members are stacked to form the stator core. Each of the core members in two of the three rows arrangement have a connecting projection angled at a first angle from the width direction of the electrical steel sheet. Each of the core members in a third row having a connecting projection angled at a different second angle from the width direction of the electrical steel sheet.
