Apparatuses employing suspended rotors are provided. In one embodiment, an apparatus includes a housing forming an internal cavity and a rotor disposed in the internal cavity of the housing. The rotor has a first end and a second end. The apparatus also includes a first end ring coupled to the first end of the rotor and a second end ring coupled to the second end of the rotor. The first end ring and the second end ring are each magnetically repulsed from the housing to cause the rotor to be suspended relative to the housing.
