    • A high speed electromagnetic rotating machine is arranged to avoid heat generation due to mutual inductance between a stator and rotor and has a stator provided with drive windings for generating a rotating magnetic field to rotate the rotor and position control windings fitted to the stator for generating a magnetic field having a different number of poles than that of the drive windings for controlling the axial or radial position of the rotor when an electric current sufficient to unbalance the magnetic field applied to the rotor by the drive windings is supplied to the position control windings. The rotor has a cage conductors interconnected to form a plurality of closed circuits mounted to the rotor, the closed circuits having a number of poles set so that there is no mutual inductance between the position control windings and the cage conductors. The cage conductors are connected by circumferentially-divided end rings rigidly connected by a retaining ring or by axially divided end rings directly connected to the rotor shaft. In one embodiment, the cage conductors are arranged in four-pole closed circuits, the drive windings have four poles, and the position control windings have two poles.

    • An ultrasonic imaging device including a bearingless levitating rotor for rotating a reflective mirror. The device may be used to image from within a hollow object and is particularly suited for use in intravascular imaging. The levitation of the rotor is achieved by forming the rotor as a permanent magnet structure having three distinct magnet regions, two having opposing dipole moments axial to the rotor orientation and one having a dipole moment transverse to the rotor orientation, the transverse magnetic region lying between the first and third magnetic regions. The rotor is radially centered within a housing using passive magnetic suspension elements, including permanent magnet stators at opposite ends of the housing. The rotor is axially positioned within the housing with an active servo feedback controller. Position-drive and sense coils are used to move and detect the positioning of the rotor. Rotation drive coils operate on the transverse magnetic region to cause the rotor to spin. The combination of the magnetic components and the coil detection, positioning, and rotation mechanism yields an imaging device with a rotor having no direct mechanical linkages.

    • A magnetic bearing assembly (10) has an intermediate rotatable section (33) having an outer cylindrical member (30) coaxially suspended by a torsion wire (72) around an axially polarized cylindrical magnet (32). Axial alignment between the pole faces (40-43) of the intermediate section (33) and end surfaces (50-53) of opposed end bells (20, 22) provides a path of least reluctance across intervening air gaps (60-63) for the magnetic flux emanating from magnet (32). Radial dislocation increases the reluctance and creates a radial restoring force. Substitution of radially polarized magnets 107 fixed to a magnetically permeable cylinder (32') and insertion of pairs of armature coil windings (109-112) between the cylinder pair (33') provides an integral magnetic bearing and torsion motor (100) able to provide arcuately limited rotational drive.
