<p>The application is typically to totally enclosed torque motors which can be operated for appreciable periods at a speed well below the synchronous. In order to remove heat from the rotor, thermally conducting inserts (4a) are placed in the stator slot openings. These are then attached to the stator frame (1) so that the heat is dissipated to the surrounding air. The stator end windings (3) can also be enclosed by the heat transfer system (4, 4b). In addition to acting as a heat sink for the rotor thermal losses the structure (4) also serves as a thermal shield for the stator windings. The thermally conducting material is normally copper or aluminium.</p> |
