    摘要： A motor generally has a contradictory relation between decrease of cogging torque and increase of torque density. To overcome this problem, continuous direction control is provided for anisotropy with modification of magnetic poles so that the average absolute value of differences between Mθ and 90×sin [φ{2π/(360/p)}] is set to be 3° or less, where Mθ is a direction of anisotropy with respect to a radial tangent line of a magnetic pole plane, φ is a mechanical angle, and p is the number of pole pairs.
