Abstract: A linear actuator includes an actuator housing. The actuator housing includes a plurality of motors providing linear movement along a motor drive axis wherein the motor drive axes are parallel, and wherein the motors are within the housing. Each motor includes a stator for applying an electromagnetic force and a rod movable within the stator. The electromagnetic force from the stator drives the rod to extend from and retract into the stator along the motor drive axis of that motor.

Abstract: An excitation circuit includes an operational amplifier, a transistor circuit, a switch, and a pull-down resistor. The operational amplifier receives an excitation input voltage at a non-inverting input and provides an operational amplifier output. The transistor circuit receives the operational amplifier output and provides a transistor circuit output. The transistor circuit output is connected to an inverting input of the operational amplifier. The switch is connected between the operational amplifier output and the transistor circuit. The switch is opened to disconnect the operational amplifier output from the transistor circuit. The pull-down resistor is connected between an output of the switch and ground, wherein the pull-down resistor turns off the transistor circuit when the switch is opened.
