Abstract
An alternator including a rotatably-assembled permanent magnet, the magnetization direction of the magnet being orthogonal to the rotation axis, and a winding with no iron core surrounding the magnet and having each turn in a plane substantially parallel to a plane containing the rotation axis, the winding extending across a dihedral angle from the rotation axis smaller than 75 degrees and, radially, over a distance ranging between one quarter and half of the magnet diameter.
