Abstract
The invention relates to a torque motor comprising a stator and a rotor that extend along a common central axis. The stator includes an integral magnetic body and at least one pair of radial teeth that extend along the central axis and define slots for receiving stator windings, and at least one permanent magnet supported by the integral magnetic body. The torque motor also includes a winding support for the stator windings that has a hollow body that extends along the central axis and that delimits a chamber for receiving the rotor, and cavities for receiving the stator windings. In this way, the stator windings are integrated in the stator by the winding support, fitted with the stator windings, being axially inserted into the integral magnetic body.
