An electromechanical rotation converter having at least one fastening element, an oscillating element, a connecting element and an electromechanical conversion device. The fastening element is designed to fasten the rotation converter to a rotating body. The connecting element forms a movable connection between the fastening element and the oscillating element, and the movement of the oscillating element drives the electromechanical converter. The connection between the fastening element and the oscillating element is such that the center of mass of the oscillating element follows a curved path in such a way that the path describes the perimeter of a surface, the normal to the surface being at an angle to the axis of rotation that is less than 90 degrees and greater than 0 degrees.
