Abstract
Abstract A device used as an electro-mechanical converter includes a body having a spherical outer surface, a structure peripherally surrounding the spherical body and electromagnetic means spatially located from the body to cause a rotational displacement of the body. The body is connected to a static support and all rotational motions are relative thereto.
