Patent ID: 7586229

Claim:
A motor comprising: a ferromagnetic member with first and second portions; a conductive wire wrapped around the first portions of the ferromagnetic member; and at least one magnet rotatably coupled to the ferromagnetic member having first and second poles and generating magnetic flux, the ferromagnetic member and the at least one magnet being configured such that at least a portion of the magnetic flux passes from the first pole of the at least one magnet, into the first portions of the ferromagnetic member, to the second portions of the ferromagnetic member, from the second portions of the ferromagnetic member, and into the second pole of the at least one magnet, the at least a portion of the magnetic flux passing through the conductive wire an odd number of times during said passing from the first pole of the at least one magnet to the second pole of the at least one magnet and when current is conducted through the conductive wire, a Lorentz force is generated between the conductive wire and the at least one magnet causing the at least one magnet to rotate relative to the ferromagnetic member, wherein said rotation of the at least one magnet relative to the ferromagnetic member is greater than 360° and the current is conducted through the conductive wire in only a first direction during said rotation of the at least one magnet relative to the ferromagnetic member.
