Abstract
An apparatus has a first motor for moving an actuator, a first brake for selectively braking the motor, a second brake that is engaged, the second brake dissipating torque spikes in the system, and a gear attaching the first motor to the actuator to cause the actuator to move and to the second brake whereby the torque spikes overcome stiction in the engaged brake so that the torque spike is dissipated in the engaged brake
Claims18
An apparatus comprising:
- a first motor for moving an actuator,
- an engaged brake for dissipating torque spikes in said EMA, and
- a gear attaching said motor to said actuator to cause said actuator to move and to said engaged brake whereby said torque spikes overcome stiction in said engaged brake so that said torque spike is dissipated in said engaged brake.
An apparatus for dissipating a torque spike therein comprising:
- a first motor for moving an actuator,
- a second motor for moving said actuator said second motor moving said actuator upon failure of said first motor,
- an engaged brake attaching to said second motor for dissipating torque spikes in said system, and
- a gear attaching said first and second motor to said actuator to cause said actuator to move and to said engaged brake whereby said torque spikes overcome stiction in said engaged brake so that said torque spike is dissipated in said engaged brake.
