  • Numerical analyses of trapped field magnet and stable levitation region of HTSC

    Stable levitation with a permanent magnet and a bulk high T/sub c/ superconductor (HTSC) is examined numerically by using the critical state model and the frozen field model. Differences between a permanent magnet and a trapped field magnet are discussed in terms of the levitation force property. The stable levitation region of the HTSC on a ring magnet and on a solenoid coil are calculated using numerical methods. The obtained results are discussed from the point of view of differences in magnetic field configuration.<<ETX>>

  • Direct electrostatic levitation and propulsion

    A new type of mechanism, called "direct electrostatic levitation and propulsion" (DELP), has been successfully developed. The novel aspect of this mechanism is that an object can be directly levitated and driven via electrostatic forces. In this paper, a brief review of the basic principles of this system is presented. This is followed by a description of the structure of a prototype DELP mechanism, including electrode design, position feedback control method for levitation, driving principle and operational procedures. Experimental results which demonstrate completely contactless transportation of a 3.5 inch aluminum hard disk media are also presented.

  • Using tilt-control in non-contact manipulation systems: Development of 2-DOF tilting actuator with remote center of rotation

    Levitation systems allow delicate objects to be handled without contact by actively controlling a levitation force that suspends the object. A drawback of levitation systems for thin objects is that the lateral force can not be controlled actively and is much weaker than the levitation force. This is a problem for non-contact manipulation systems as the object may loose its alignment with the levitator (and drop) because of the inertial forces coming from the lateral accelerations. In earlier work, a solution was proposed using Tilt Control in which lateral accelerations are compensated by the levitation force by tilting both the object and the levitator. This concept has been verified in an experimental setup that was capable of tilting around only one axis. In this paper, a new and unique design is presented of a tilting actuator that is capable of rotating around two axis, so that full 3D-space manipulation is possible. A key aspect of the Tilt Control strategy is that the center of rotation is at the center of mass of the levitated object and, for the tilting actuator, this means that it should have a remote center of rotation. A spherical cap or dome-shaped structure supported by three ball bearings, is used as the fundamental principle for the tilting actuator design as it has a natural remote center. The design and realization of this tilting actuator are described in this paper and a pilot experiment was carried out in which the tilting actuator, with a magnetic levitator installed, was attached to a linear motor. The results showed successful tilting action as relative lateral motion of the levitated object were significantly reduced on two axis.

  • Electrical motor with bulk Y-Ba-Cu-O pellets

    The interaction between a magnetic field and a superconducting (SC) bulk sample produces not only levitation forces but also transverse ones. They may be used in an electromagnetic coupling device to transmit a torque or in an electrical motor to produce a torque. The authors have designed and built a disk type motor (vertical axial gap) with a static three-phase armature resistive winding and a rotating part composed of eight YBaCuO pellets immersed in a liquid nitrogen vessel. The SC samples are melt textured using the top seed melt texturing method. The armature winding is fed by a power converter. Then the supplied frequency and the speed of rotation are variable. The motor was tested in different conditions and operated without magnetizing the SC samples. It works in a way as a variable reluctance motor even if the hysteresis behaviour of the SC pellets complicates the operation. Other experiments were carried out magnetizing the SC samples before their use as an inductor. The operation is close then to a permanent magnet motor. The experimental set up and the different tests are reported.
