Abstract: PURPOSE: An ER(electro-rheological) clutch type pneumatic reversible motor is provided to control the motor easily and to enhance the mechanical reliability as well as to rotate at a high speed and forward/reversely by applying the excellent performance of an ER clutch to a reversible motor. CONSTITUTION: A pneumatic reversible motor is controlled through the forward/reverse rotation of an output rotor(303) of an ER clutch. That is, each electrode face of inner/outer rotors(301,302) forms electric fields with voltage to induce sequential solidification of ER fluids. The output rotor is revolved by the stress of the ER fluids. Therefore, the output torque and speed responds rapidly by setting the mass inertia of the output rotor smaller than one of a DC servomotor. The insulation is prepared by using an insulating plastic to a housing(308) and coating an outer cylinder of the ER clutch. Finally, the ER fluid leakage is prevented by applying a lip seal(306).
