Rotor for electric motors

摘要

A wholly or substantially magnetically non-conducting rotor for a motor, on and around which rotor is located one or more asymmetric and/or outstanding magnetically conducting elements adapted to cause rotation of the rotor by one or more magnets located therearound in use is described herein. The rotor is suitable for use in stepping motors using electro magnets, movable permanent magnets or magnetic shields. Fig. 7a shows an arrangement permitting reverse rotation. Asymetric electromagnet disposition is disclosed (Fig. 5A - C).
