Built Tough N20 Linear Actuator DC Reduction Motor Loaded With Pure Copper Coils 6V 12V 500RPM Range And 100MM M4 Shafts For Killer Robot Arms And Smooth DIY Automation Builds

Single N20 DC Reduction Linear Actuator with M4 Shaft
✔️ Single N20 gear motor 6V 12V copper winding M4 shaft 100mm

This linear actuator pairs an N20 reduction motor with a threaded lead screw to convert rotary motion straight up and down or forward. You will find it handy for robotic arms, mini lift platforms, and automated sliding fixtures where precise travel control matters without drawing too much power from small battery packs.

✅ Pure copper wire winding cuts power loss and runs cooler during long duty cycles
✅ Metal pinion gears deliver steady torque output with minimal acoustic noise under heavy loads
✅ M4 threaded lead screw enables smooth linear travel across full stroke range

💡 How do you pick the right thrust and speed ratings for an automated slider mechanism?
Pick the right setup by running a couple of basic load calculations before you mount it.
- Calculate total pushed weight plus friction factor to match the N20 motor torque curve
- Choose lead screw pitch based on how fast you need the carriage to travel per minute
- Install a variable voltage driver so you trim acceleration spikes without stalling threads
