ABSTRACT:
The present invention relates to a system for driving two mechanical members in rotation about an axis by magnetic coupling of the attractive type, the system comprises respective magnetic elements secured to each of said mechanical members, the two magnetic elements being concentric, one of them being made up of two identical magnetic rings of minimum radius R.sub.3 and of maximum radius R.sub.4, and the other one of them being made up of a magnetic ring having a minimum radius R.sub.1 and a maximum radius R.sub.2, with its midplane perpendicular to the axis of rotation being offset by a distance d from the midplanes of each of said two identical rings. Each ring possesses magnetization in a direction contained in a plane that is perpendicular to the axis of rotation. Each ring also possesses N magnetic poles uniformly distributed around said axis of rotation. The ratio 2d/.vertline.(R.sub.3 +R.sub.4)-(R.sub.1 +R.sub.2).vertline. lies in the range 0.2 to 0.8.
