Mini Micro Metal Gear Motor

The Ruth's sister 270B13AC800920 is a miniature DC motor with integrated metal gear reduction. It operates on a 3-9V supply and delivers 185 RPM at 3V. The 9.5mm D-type shaft and 15-22cm wire leads suit compact mechanical projects.

Hobbyists building small actuators

This motor suits builders who need a ready-to-go geared drive for lightweight mechanisms such as camera gimbals or valve actuators. Buyers who require higher torque, faster speed, position feedback or a different shaft diameter should look elsewhere.

3-9V range with 185 RPM at 3V

The gearbox provides usable torque for small loads at low voltage, making it comfortable for battery-powered prototypes. It runs out of headroom when the load exceeds the gearbox rating or when continuous operation demands more current than the 3V brushed windings can supply.

Highlights

  • Low-speed torque for precise mechanisms
  • 3–9 V operation with 185 RPM at 3 V
  • Clockwise and counter-clockwise rotation selectable
  • Compact 1.2 × 0.9 × 1 cm metal gearbox
  • 5 mm D-shaft with 15–22 cm leads

Questions about this item

What voltage source do I need to run this 3-9 V motor at its rated 185 RPM?

Supply any DC voltage between 3 V and 9 V; the motor is specified to turn at 185 revolutions per minute at 3 V.

Will the 3 mm D-shaft fit the gear or wheel I already have?

The output shaft is 3 mm diameter with a D-shaped flat and 9.5 mm long, so it matches standard N20 pinions and wheels bored for that size.

How can I confirm the motor is rotating in the direction I wired it for?

Apply power and watch the shaft — it turns clockwise or counter-clockwise depending on polarity, giving immediate visual confirmation.
