Haydon Kerk Motion Solutions Inc., has introduced the MotoDrive PDE Captive Linear Actuator, available in size 17 single or double stack. The MotoDrive comes with an integrated chopper drive forming a compact system that is suitable for precision motion control applications. The MotoDrive captive linear actuator system is capable of an output force of 220N for the single stack version and 350N for the double stack version.

The captive configuration allows a self-contained linear actuator unit with an anti-rotation device guiding a splined output shaft. The captive configuration of the MotoDrive is suitable for applications requiring shorter stroke lengths (up to 2.5in) such as precision fluid dispensing, throttle control, and valve movement.

The load connects to the threaded shaft end. Hold current on the drive is adjustable and can be selected as zero, 25, 50, 75 or 100% of run current using a jumper and associated pins located in a connector on the side of the drive.
