Abstract: A system and method for perturbing a permanent magnet asymmetric field to move a body includes a rotating body configured to rotate about a rotation axis, a permanent magnet arrangement arranged on the rotating body containing two or more permanent magnets, and a perturbation element. The permanent magnet arrangement is configured such that an asymmetric magnetic field is generated by the permanent magnets about a perturbation point.

The disclosure may also be used for linear motion of a body.

The rotor magnet and the stator magnet have a gap therebetween. There is an equilibrium state position (ESP) of the rotor magnet where forces acting on the rotor magnet are balanced such that the rotor magnet is stationary about the rotor magnet axis.
