1. A motor comprising a stator core formed by stacking a plurality of noncircular core sheets, each of which is made from a rolled magnetic steel sheet, wherein
the stator core includes:
a first core sheet; anda second core sheet having an outside edge shape the same as the first core sheet, the second core sheet being stacked with respect to the first core sheet so that a rolling direction of the second core sheet becomes a direction rotated from a rolling direction of the first core sheet about a center axis of the stator core by an angle of an odd multiple of 360°/(number of poles of the motor×2), wherein the outside edge of the first core sheet has a first and second sides at both ends in a direction perpendicular to the rolling direction of the first core sheet, the first and second sides being parallel to the rolling direction of the first core sheet, wherein the outside edge of the second core sheet has a third and fourth sides at both ends in a direction perpendicular to the rolling direction of the second core sheet, the third and fourth sides being parallel to the rolling direction of the second core sheet, wherein a dimension in the direction perpendicular to the rolling direction of the first core sheet between the first side and the second side, and a dimension in the direction perpendicular to the rolling direction of the second core sheet between the third side and the fourth side are the same. |
