1. A hybrid actuator through which a linear drive is applied to a load, comprising: an actuator shaft connected to the load; a plurality of electrically energized motors positioned over the shaft; a plurality of solid-state thrusters positioned on the actuator shaft in operative relation to the motors; clutch means mounted on the actuator shaft in engagement with the thrusters for transfer of thrust force to the actuator shaft during operation in response to energization of the motors; and amplification means for amplifying force and stroke output of said motors to cyclically control said operation of the clutch means and effect said drive of the load. |
