Abstract: A magnetically levitated motor includes a stator, a rotor configured to rotate relative to the stator, and a passive radial magnetic bearing configured to support the rotor relative to the stator in a radial direction. An active longitudinal magnetic bearing is configured to selectively position the rotor relative to the stator in an axial direction.

Abstract: Disclosed is a signal analyzer that can receive a signal generated by an external system. The signal has a plurality of frequency components. The signal analyzer generates a suppressed phasor domain representation of the signal by selectively removing at least one component for use as a reference. The signal analyzer then displays the suppressed phasor domain representation of the signal. In one embodiment, the signal analyzer removes the component of greatest magnitude. The signal analyzer can also (or alternatively) remove a user selected component. In addition to the suppressed phasor domain, the signal analyzer can simultaneously display the frequency domain, the time domain, the numerical domain, and/or the modulation domain.
