Radial force in a bearingless reluctance motor
Abstract
A fourpole reluctance synchronous machine with additional twopole windings was constructed. The additional winding currents produce the radial force to act as a magnetic bearing. Expressions for the machine inductance functions are given. Inductance functions with respect to the eccentric displacement of the rotor were measured. The contribution of these inductances to the radial force production is established.
