  • Patent number: 10916993
    Abstract: A torque motor includes a large area rotor, a stator surrounding at least a portion of the rotor, and a small air gap separating the rotor from the stator to allow frictionless thermal coupling between the rotor and the stator. Heat from the rotor is transferred to the stator by conduction. The stator contacts an inner surface for a housing of the torque motor for conductively coupling to a cold environment air flow exterior to the torque motor housing. The air gap may have a dimension of about 0.002 to 0.003 inches. The stator may be conductively coupled to the torque motor housing by one of a thermal gap pad or high conductivity thermal gap filling compound. Heat conduction from the rotor to the stator preferably occurs without rotation of the rotor.
