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.

A power generator assembly comprising:
- a rotating part, and
- a non-rotating part, wherein the rotating part includes at least one generator unit having at least one coil (20), at least one permanent magnet and two pole shoes having pole surfaces facing radially outward, 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.
A railway bogie side frame comprising:
- a side frame, and
- a power generator assembly configured to function in association with the side frame, the power generator assembly having a rotating part, and a non-rotating part, wherein the rotating part includes at least one generator unit including having at least one coil, at least one permanent magnet and two pole shoes having pole surfaces facing radially outward, 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.
