摘要：Aspects of the disclosure provide an electric actuator including a first drivingsource coupled to an output through a first pathway created by a transmission, a seconddriving source coupled to the output though a second pathway created by thetransmission that, upon the electric actuator losses electrical power to the electricactuator, causes the output to be positioned at a fail-safe position, a differential coupledto the first driving source and the second driving source through a third pathway createdby the transmission to store energy from the first driving source in the second drivingsource, and a switching controller that is configured to control switching the transmissionbetween the first pathway, the second pathway, and the third pathway.
