Abstract
Mechanical systems including a pair of rotatable magnetic rollers are provided. Each roller includes a set of magnets mounted on a rotating shaft. Each magnet in the sets is diametrically magnetized. Methods of reducing or eliminating a torque to rotate the magnetic rollers are provided.
Claims21
A mechanical system comprising:
- a first magnetic roller including a first set of magnets mounted on a first rotating shaft extending along a first rotation axis;
- and
- a second magnetic roller including a second set of magnets mounted on a second rotating shaft along a second rotation axis substantially parallel to the first rotation axis, the first and second magnetic rollers being positioned with a gap therebetween,
- wherein each magnet in the first and second sets is diametrically magnetized with a magnetic orientation substantially perpendicular to the first or second rotation axis.
