  • Patent number: 5287755
    Abstract: An actuator has a driven shaft for an armature, a final torque switch and at least one electric lead. A process for verifying the cutoff torque of an actuator of an armature includes lifting the actuator away from the armature while keeping at least one electric lead connected to the actuator, connecting a torque measuring shaft and a brake connected to the torque measuring shaft to the driven shaft of the actuator, operating the actuator in the immediate vicinity of the armature and then braking the actuator until response of the final torque switch to ascertain a cutoff torque, and comparing the cutoff torque with a set-point cutoff torque. An apparatus for verifying the turnoff torque of an actuator of an armature includes a torque measuring shaft and a brake being connected to each other.
