Magnetic bearings levitate a rotating object (typically, a rotor) with a magnetic field, and are unstable in open-loop operation. Position feedback control is required to maintain the rotor in a centered position. Typically, a separate position sensor is used to directly measure the rotor’s position for use in this feedback loop. Self-sensing magnetic bearings use the bearing’s electrical signals to estimate rotor position. There are two primary classes of self-sensing methods: state estimation… CONTINUE READING
