The 20DAM-K is a captive miniature linear actuator based on a can stack stepper motor design, converting rotary motion to linear motion via an integrated leadscrew. It has a 20 mm diameter housing and a 15 mm stroke length. The 20DAM10D2U-K variant operates at 5 VDC with a unipolar winding, drawing 0.35 A per phase, and delivers 30.6 N of holding force at rated current. It features ball bearings, operates from -20 °C to +70 °C, and has a maximum coil temperature of 130 °C. The motor has 24 steps per revolution, ±1 step linear travel accuracy, and uses AWG #28 leadwires. It is RoHS compliant and weighs 25 g.
20DAM-K Linear Actuator Stepper Motor
20DAM-K
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).
