Linear actuator uses a lead screw driven by a permanent magnet dc motor to create linear motion from a dc voltage. When power is removed linear actuator will hold its position. However, if a force ...

The ABCs of PID control. Considerations for interfacing elements in the electrical circuit to accomplish those parts of the PID function for position control. Firmware code implementation.

Vice President Copley Controls Corp. Canton, Mass. Historically, industry has depended on ball screws, belt drives, and pneumatic mechanisms for automation’s positioning tasks. But the rising demand ...

Moving a load in a straight line can be done using a variety of linear actuator devices employing both rod and rodless technologies. For rod-style actuation requiring lower amounts of force ...

In recent years industry has shown growing interest in linear ultrasonic piezoelectric actuators and ultrasonic drives. Well-known manufacturers of micropositioning systems have increasingly put ...
