NON-CONTACT ACTUATOR

摘要

PURPOSE:To make it possible to make an effective drive by a simple circuit constitution by winding and loading an exciting coil for levitation and rotation on each magnetic pole of a stator and rotating a rotor in a state of magnetic levitation against the stator. CONSTITUTION:A plural number of groups of magnetic poles MG1-MG8 are formed onto a stator 1, and four or more magnetic poles MP1-MP4 are formed onto each group of magnetic poles MG1-MG8. One exciting coil L1-L4 for levitation and rotation is wound and loaded on each magnetic pole MP1-MP4. The rotation is made in a state of non-contact with magnetic levitation against the rotor 2 and the stator 1 by applying levitation control current and rotation current to those exciting coils L1-L4 for levitation and rotation one on top of another.
