Title:
磁気カップリング装置
Document Type and Number:
Japanese Patent JP7463222
Kind Code:
B2
Abstract:
A magnetic coupling device includes a driving magnet array having multiple annular sector-shaped, circumferentially arranged first permanent magnets, and a driven magnet array having multiple circular sector-shaped, circumferentially arranged second permanent magnets with pole surfaces facing pole surfaces of the first permanent magnets. The driven magnet array is rotated by the driving magnet array being rotated. A repulsion zone where a repulsive force acts is designed to have an area that is 5% to 15% of that of an attraction zone where an attractive force acts between a specific first permanent magnet and a specific second permanent magnet, with a radial first centerline of the specific first permanent magnet overlapping a radial second centerline of the specific second permanent magnet so that opposite poles face each other, including between first and second permanent magnets respectively adjacent the specific first and second permanent magnets with overlapping the centerlines.
