  • 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.

  • Publication number: 20040200398
    Abstract: An essentially cylindrical, elongate pressure hull includes at least one pressure antechamber arranged essentially transversely to a longitudinal axis of the pressure hull. The pressure antechamber includes an access opening to the pressure hull which is closable in a pressure-tight manner and an access opening to the outside which is closable in a pressure-tight manner.

  • Publication number: 20030178895
    Abstract: The invention relates to a torque motor, especially a fuel cell torque motor, which converts the 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. According to the invention, the torque motor is provided with fuel cells that serve as an internal energy source, whereby said fuel cells are arranged in the stator around the rotational axis of the motor in an annular manner. The torque motor is comprised of a rotor (1) and stator (6) with permanent magnets (2) arranged on said rotor (1) and with armature windings located in the stator. Said armature windings are supplied with current from a commutator (3) having electronic power components, whereby fuel cell modules (4) and fuel cell supply and control elements (5) are integrated in the commutator in a structurally modular-like manner.
