Abstract

The present invention concerns a magnet-assisted ball drive. The drive comprises a ball and a drive element in contact with the ball. The drive element is arranged to be rotated around its axis of rotation to drive the ball. The ball and the drive element each comprise magnetic material such that at least one of the ball and the drive element comprises a magnet to generate a magnetic pulling force to pull the ball and the drive element against each other.
