Unique-Bargains JGA12-N20 DC 3V 50RPM micro gearbox machinery motor

SKU CH-Z7TZ-Q271X MPN JGA12-N20

A compact DC 3V motor with a metal gearbox delivering 50RPM and high torque for small-scale projects

  • Metal gearbox boosts torque for small drives
  • 50 RPM output at 3 V suits precise motion tasks
  • 10 g weight keeps miniature builds light
  • 3 mm shaft fits standard couplers and wheels
  • Suits toys, locks, instruments and medical devices

Micro 3V 50RPM geared motor

This DC micro gearbox motor delivers 50RPM at 3V and measures 17 x 11.9 x 10mm overall. A metal gearbox increases torque while keeping weight to 10g. The 3mm diameter output shaft extends 10mm for simple coupling. It is built for compact electromechanical projects.

Suits hobbyists building small RC models

Designers needing higher speed, greater torque or a different voltage should look elsewhere. Applications requiring continuous high-load duty cycles are not a good match. Buyers who need integrated encoders or mounting brackets must source those separately.

Simple two-wire connection for quick testing

Solder leads directly to the motor terminals and secure the body with adhesive or a custom bracket. The tiny 3mm shaft can slip inside oversized couplings, so verify fit before final assembly. Exceeding the rated voltage will shorten gear life.

Questions about this item

What voltage power supply do I need to run this 3V motor?

Provide a stable DC 3V source; the motor is rated for exactly 3 volts and draws low current typical of a 10 g micro gearbox.

Will the 3 mm output shaft fit the 3 mm pinion gears I already use on other N20 motors?

Yes — the shaft diameter is 3 mm and the length is 10 mm, matching the standard N20 interface used on many existing gear sets.

How can I confirm the gearbox is delivering the rated 50 RPM after I wire it up?

Mark the 3 mm shaft, run the motor at 3 V, and count revolutions for one minute; you should see approximately 50 turns.
