N20 DC 3V-12V Micro Metal Gear Motor With Gearbox – 15-4000RPM Adjustable Speed – D-Type Shaft

If you're into DIY robotics, automation, or any small-scale project, this N20 micro gear motor is a solid pick.

It runs on a wide voltage range from 3V to 12V, giving you flexible speed control from as low as 15 RPM up to 4000 RPM.

The built-in metal gearbox is tough and durable, perfect for applications where you need torque and precision.

The output shaft is a D-type measuring 3x4.4mm, so it's easy to attach wheels or gears.

It's manufactured in China, and while it's a generic unbranded model, the performance is what counts.

Speed tolerance is ±10%, so expect a little variation—but that's typical for motors like this.

Fast fulfillment means you'll get it quickly.

Great for hobbyists, tinkerers, and inventors.
