Latest Patents

Among his latest patents is the invention of reactance sensors of radial position for magnetic bearings and bearingless drives. This invention features a radial position sensor that includes a rotating element configured to rotate about an axis of rotation, which is subject to displacement. The displacement can be represented by polar coordinates, where the distance and angle are crucial for accurate positioning. The sensor employs a non-rotating emitting element that provides multiple electromagnetic fields, which are then received by a non-rotating receiving element. The electromagnetic coupling varies based on the radial position of the rotating element, allowing for precise output signals that indicate the radial position of the axis of rotation.

Another notable patent involves methods and systems for operating magnetic bearings and bearingless drives. This invention includes a magnetic bearing arrangement for a rotary device that generates a multiphase excitation signal to energize the phase windings of a magnetic bearing element. The system detects the radial position of the rotor and modifies the excitation signal accordingly, providing an efficient means for dynamically suspending the rotor.
