Joerg Hugel has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10873241
    Abstract: An electromagnetic rotary drive includes a magnetically contactlessly drivable rotor free of coils, and a stator configured as a bearing and drive stator configured to drive the rotor magnetically and contactlessly about an axis of rotation. The rotor is capable of being supported magnetically contactlessly with respect to the stator in an operating state. The stator includes an upper stator part having a plurality of pronounced upper poles configured to carry upper windings and a lower stator part having a plurality of pronounced lower poles configured to carry lower windings. The upper stator part and the lower stator part are arranged spaced apart from one another with respect to an axial direction. A permanent magnet is disposed between the upper stator part and the lower stator part.

  • Patent number: 10780408
    Abstract: A mixing apparatus for mixing substances includes a single-use apparatus and a reusable apparatus. The single-use apparatus includes a flexible mixing tank configured to receive the at least two substances to be mixed, is plastic, and has a rotor arranged in the mixing tank. The rotor includes an impeller configured to mix the at least two substances, the impeller being magnetically contactlessly drivable and free of coils and permanent magnets. The reusable apparatus includes a support tank configured to receive the mixing tank and a stator configured to magnetically contactlessly drive the rotor about an axis of rotation in an operating state. The stator includes at least one permanent magnet configured to generate a permanent magnet flux and at least one winding configured to generate an electromagnetic flux, the permanent magnet flux and the electromagnetic flux together being capable of driving the rotor.

  • Patent number: 6670169
    Abstract: A bioreactor with a reaction container (1, 1a, 1b, 1c) for a substance (C) to be acted upon with a medium has a pump (5, 5a, 5b, 5c, 5d) for conveying the medium. The pump is designed as an expendable pump or, respectively, parts (53d, 54d, 55d) of the pump are designed as expendable parts.

  • Patent number: 6100618
    Abstract: The rotary machine comprises a driven rotor and an electric motor having a stator and a driving rotor. The stator is also executed as an electromagnetic bearing for the driving rotor, and the driving rotor of the electric motor together with the driven rotor of the rotary machine forms a rotor unit, i.e. the two rotors form an integral rotor. The rotary machine can for example be a rotary pump, a centrifugal pump, a centrifuge or a stirring apparatus. The rotor can be constructed so as to be easily removable from the stator.
