Abstract
It has been confirmed that even though there is a difference in the dimension of a perpendicular reference surface of a permanent magnet, there is almost no change in surface magnetic flux density, and variations in the dimension of the perpendicular reference surface do not much affect the surface magnetic flux density. Therefore, even though variations occur in the dimension of the perpendicular reference surface, variations in the characteristics of an IPM motor are prevented.
