Abstract

A magnetic bearing arrangement for a rotary device includes circuitry for generating a multiphase excitation signal for energizing the phase windings of a magnetic bearing element. According to an embodiment of the present invention, circuitry for detecting the radial position of a rotor of the rotary device generates a position signal indicative of the radial position of the rotor of the rotary device relative to a desired rotor position. The position signal is used to modify the excitation signal to produce a modified excitation signal. The modified excitation signal is used to energize the phase windings of the magnetic bearing, thus providing a low-cost and efficient means for dynamically suspending the rotor of the rotary device.
