Abstract (en)
[origin: EP2072755A1] The turbo-machine has a blade (1) e.g. turbine blade, aligned along a blade axis (7) and rotatably arranged at a rotation axis, and a housing arranged at the blade. An induction plate (3) is arranged in a blade tip, and magnets (5) e.g. bar magnets, arranged in the housing. The plate is aligned in a plane formed by the rotation axis and a radial direction and made of electrically conductive material. A magnetic northpole and a magnetic southpole lie in a circular path. The path is aligned rotation symmetric to the rotation axis and runs along a circumferential surface of the housing.
