Movement generating device

A method of generating movement in a system using a magnetic device comprising the steps of:

• providing an input energy source;
• providing energy from said input energy source to a shaft adapted for linear movement substantially along a first axis;
• connecting a first traction magnetic device in a first sub-system to said shaft and to an article;
• providing a first power magnetic device and a first base magnetic device in said first sub-system, wherein the first traction magnetic device is movable with respect to the first base magnetic device and wherein the first base magnetic device and the first power magnetic device are stationary;
• providing a second traction magnetic device, a second base magnetic device and a second power magnetic device in a second sub-system, wherein the second base magnetic device is stationary and the second traction magnetic device is movable relative to the second base magnetic device, wherein the second power magnetic device is stationary;
• connecting said second traction magnetic device to the shaft thereby balancing the magnetic force of the first traction magnetic device in the first sub-system;
• wherein during a first part of a cycle of the movement generating device the first traction magnetic device moves across the first power magnetic device through contact between the first traction magnetic device and the first base magnetic device, the produced movement moving the article in a first direction due to rotation of said shaft about said first axis in a first rotational direction, wherein simultaneously the second traction magnetic device contacts the second base magnetic device in said second sub-system;
• wherein said shaft subsequently moves in a first axial direction, whereupon the first traction magnetic device is in contact with the first base magnetic device such that the shaft rotates in a second rotational direction, opposite to said first rotational direction, and the second traction magnetic device moves across the second power magnetic device through contact between the second traction magnetic device and the second base magnetic device, the movement of the second traction magnetic device across the second power magnetic device enabling said article to move in a second direction, opposite to said first direction;
• wherein said shaft thereafter moves in a second axial direction, opposite to said first axial direction, until said first part of the cycle starts again.
