Abstract
A linear actuator system is described that includes a linear actuator, a first motor, and a second motor. The linear actuator is configured to transmit rotational motion to linear motion. The first motor is operatively connected to the linear actuator. The second motor is also operatively connected to the linear actuator. The first motor is configured to provide a different amount of force and a different speed to the linear actuator than the second motor. Methods of operating a linear actuator are also disclosed.
