A remote controlled actuator system has a motor with a drive or screw shaft. The motor drives a sliding element propelled by the screw shaft. The control circuit may include steering diodes to minimize wires where there is sensing or more than one actuator. A remote controller may direct motor movement of individual actuators without a local controller. The remote actuator may be used to sense remote position through the steering diodes. There is a bipolar and bi-level drive circuit providing the step voltage to achieve high performance motor movement. The guideway may have an internal keyway along with an anti-rotation sliding bearing protected against rotation by the keyway. This anti-rotation sliding bearing restricts the piston to linear travel along the driving motor lead screw thread. The position sensor may include a resistive element sliding contact mounted to the sliding piston. A special coaxial mechanical coupling method simplifies installation. |
