  • Patent number: 6847142
    Abstract: A torque motor, especially a fuel cell torque motor, converts chemically stored energy of liquid or gaseous fuels, directly inside the torque motor while avoiding a separate installation of devices, into mechanical energy for driving at least one consumer. The torque motor is provided with fuel cells that serve as an internal energy source, the fuel cells being arranged in the stator around the rotational axis of the motor in an annular manner. The torque motor includes a rotor and stator with permanent magnets arranged on the rotor and with armature windings located in the stator. The armature windings are supplied with current from a commutator having electronic power components. Fuel cell modules and fuel cell supply and control elements are integrated in the commutator in a structurally modular-like manner.
