Patent ID: 8568088

Claim:
A turbomachine, comprising: a blade which is rotatably arranged around a rotational axis and oriented along a blade axis; a housing which is arranged around the blade; a plurality of induction plates which are arranged in a blade tip; and a magnet which is arranged in the housing, wherein the plurality of induction plates are oriented in a plane which is formed by the rotational axis and a radial direction, wherein a magnetic north pole and a magnetic south pole of the magnet lie on a circular path, and form a magnetic field with magnetic lines of force, wherein the blade tip is moved through the magnetic field, wherein the circular path is oriented rotationally symmetrically around the rotational axis, wherein the plurality of induction plates is oriented parallel to the rotational axis and parallel to the radial direction, wherein the plurality of induction plates is oriented perpendicularly to the magnetic field, wherein the plurality of induction plates is electrically conductive and creates eddy currents when moved through the magnetic field, and wherein the plurality of induction plates are electrically insulated from each other.
