Abstract:
1. A system comprising: a rotational member that is configured to rotate about an axis, wherein the rotational member comprises a magnetically interactive path that extends between an outer position that is at a first distance from the axis and an inner position that is at a second distance from the axis, wherein the first distance is greater than the second distance; and a transverse assembly that comprises one or more magnetically interactive members that travel in a radial direction from the outer position to the inner position of the magnetically interactive path of the rotational member, wherein movement of the one or more magnetically interactive members causes the rotational member to rotate about its axis due to magnetic attraction between the one or more magnetically interactive members of the transverse assembly and the magnetically interactive path of the rotational member, wherein the magnetic attraction between the magnetically interactive path of the rotational member and the one or more magnetically interactive members of the transverse assembly is such that a torque generated at the outer position of the magnetic path is greater than an opposing torque generated at the inner position of the magnetic path such that the rotational member continues to rotate due to the imbalance of the opposing torques.
