Abstract
A rotating part that includes at least one generator unit having at least one coil, at least one permanent magnet and two pole shoes having pole surfaces facing radially outward is provided, The non-rotating part has an arc-shaped saddle adaptor of ferromagnetic material arranged with a radial distance to the pole surfaces. The saddle adaptor is configured to close a magnetic circuit passing via the pole shoes through the coil in a rotational position where the saddle adaptor overlaps with the pole shoes of the generator unit.
Claims13
A power generator assembly comprising:
- a saddle adapter configured to be engaged by a train bogie side frame to secure an axle thereto;
- a rotating part configured to rotate underneath the saddle adapter,
- a non-rotating part located radially outside of the rotating part,
- wherein one section of the rotating part includes at least one generator unit having at least one coil, at least one permanent magnet and two pole shoes having pole surfaces facing radially
- outward and another section includes electronic devices, the saddle adapter being configured to overlap the two pole shoes of at least one of the at least one generator unit,
- wherein the non-rotating part includes an arc-shaped saddle adaptor of ferromagnetic material arranged with a radial distance to the pole surfaces, and
- wherein the saddle adaptor is configured to close a magnetic circuit passing via the pole shoes through the coil in a rotational position where the saddle adaptor overlaps with the pole shoes of the generator unit.
