Linear actuator 20DAM-K series

electricsteppersingle-acting

The smallest of our miniature linear stepper motor line, is the 20DAM-K which is a high-performance captive miniature linear actuator that provides up to 30.6 N of linear force in a 20mm frame size. The miniature linear motor is a can stack stepper motor with a built-in leadscrew to directly convert rotary motion into linear motion. Using the basic can stack stepper motor design, the miniature linear stepper actuator has a 15 degree step angle. The rotor magnet sits on a thermoplastic nut captured between two ball bearings secured in the end caps. Depending on the level of integration required, the DLA can be captive (limited travel) or non-captive (extended travel). Product Highlights • High continuous linear force output for size • Digitally controlled - easy to use with a micro processor • Cost effective - compact design, lower integration cost • Maintenance free - no brushes to replace • Unipolar and bipolar winding options • Captive and non-captive linear actuator designs • Long life - ball bearing design Customization Available • Coil modifications - resistance and inductance • Higher strength plastics for higher impact forces • Magnets - to yield higher linear force or reduced detent levels • Reduced or increased detent force to suit the application • Screw - metric or imperial tips, length • Special flanges, connectors, end of motion detection sensors • Wiring - connectors, lead length, shrink tubing Applications • Motors for Medical Pipettes • Damper Actuation • Flap Actuation • Printers and Copiers • Switching Systems
