    摘要: The invention relates to a coil system for the contactless magnetic navigation of a magnetic body (1) in a work space, wherein the coil system comprises a plurality of coils and a current controller for controlling the respective currents in the plurality of coils. In order to navigate the magnetic body (1) to a variably predeterminable position (P) in the work space, the current controller is designed such that the currents in the plurality of coils are such that the magnetic forces (F
    1 , F
    2 , F
    3 , F
    4 ) generated by the currents and acting upon the magnetic body (1) at multiple positions (P
    1 , P
    2 , P
    3 , P
    4 ) at the edge of a convex environment (Ω) around the predetermined position (P) are directed into the environment (Ω). The coil system according to the invention has the advantage that a movement of the magnetic body toward a spatial position is achieved without any mechanical movement of the coil system and without a positioning system for determining the position of the magnetic body. The coil system is utilized particularly in a medical device, wherein a magnetic body in the form of a probe is moved in the body of a patient. In this way, fast navigation of the probe in the patient’s body can be achieved without mechanical movements of the patient table or of the coil system.

    摘要: The motive device (14) includes a motor (26) attached to a magnet chamber (40). The magnet chamber connects to the exterior of the agitator tank (16) and houses a drive magnet (28) and a shaft (30) connecting the motor to the drive magnet. The impeller apparatus (12) generally includes an axial-pumping impeller (22) attached to a driven magnet (32). The impeller is supported by at least one post so that it is held away from the bottom of the tank. The impeller is attached via a post and bearing structure (34) to the driven magnet. The post and bearing structure includes a sleeve (38) coaxial with a post (36), and which sleeve can rotate around the post. The sleeve is attached at one end to the driven magnet and the other end to the impeller.

    摘要: A system and method are used to levitate and translate a stage within a chamber using a motor assembly coupled to a balance mass assembly. The balance mass assembly is positioned adjacent the chamber. The motor assembly includes a stator and a coil. One of the stator and the coil are coupled to the stage on a first side of a wall of the chamber. The other of the stator and the coil are coupled to the balance mass assembly on a second side of the wall of the chamber. A magnetic assembly coupled to the stage allows the stage to levitate within the chamber. Once levitated, the stage is translated based on the interaction of the magnets and an energized coil.

    摘要: A magnetic levitation control apparatus comprises a pair of electromagnets for holding a levitated body having a magnetic body in the levitated state. A signal source for supplying a voltage signal of a frequency on a level such that enables the electromagnets to function as the position sensor, wherein a control voltage signal for controlling the magnetic attraction of the electromagnets is superimposed on the voltage signal. A circuit differentially supplies the voltage signal to the pair of electromagnets to form a position signal of the levitated body from an add signal of currents respectively from the electromagnets, and a circuit detects a control current of the electromagnets from a subtraction signal of currents respectively from the electromagnets. A controller generates a control voltage signal of the electromagnets from the detected position signal of the levitated body and, in addition, corrects the position signal detected from the detected control current of the electromagnets.

    摘要: A system for pumping or mixing a fluid using a levitating, rotating pumping or mixing element and various other components for use in a pumping or mixing system as disclosed. The pumping or mixing element is placed in a fluid-containing vessel in close proximity to a superconducting element. A cooling source thermally linked to the superconducting element provides the necessary cooking to induce levitation in the pumping or mixing element. The superconducting element may be thermally isolated, such that the pumping or mixing element, the vessel, and any fluid contained therein are not exposed to the cold temperatures required to produce the desired superconductive effects and the resulting levitation. By using means external to the vessel to rotate and/or stabilize the pumping or mixing element levitating in the fluid, including possibly rotating the superconducting element itself or moving it relative to the vessel, the desired effective pumping or mixing action may be provided.
