Abstract
Devices of the invention include a rotor with magnets and a stator with two magnet zones. The end zone of the stator toward which the rotor magnet first approaches has two preferred variants: it can be formed either of one magnet or of a high magnetic permeability material. The other end of the stator is preferably formed of thick magnets.
Claims2
A magnetic rotary device, comprising:
- a rotor comprising at least one rotor magnet having magnetic poles;
- a shaft about which the rotor turns;
- a stator comprising at least one stator magnet having two magnetic poles that sequentially face the rotor magnet as the rotor turns;
- and
- a magnet or a high magnetic permeability material at the end of the stator that is first approached by the rotor magnet as the rotor turns, which directs a magnetic field at the end of the stator;
- whereby when the rotor magnet approaches the stator a magnetic attraction takes place causing the rotor to turn.
