SKU CH-ZGTK-8H4HS

A micro metal gear motor with D-shaft output running at 66 RPM from a 3 V to 9 V supply

  • Micro gear motor delivers 66 RPM at 6 V
  • D-shaft output enables secure gearwheel coupling
  • Wide 3 V to 9 V input suits variable power sources
  • Compact 12×20 mm form factor fits tight chassis spaces

Micro gear motor for low-speed projects

The Ruth's sister G12-N20 micro metal gear motor delivers a rated speed of 66 RPM at 6 V. It operates across a 3 V to 9 V range and includes a gearwheel with a D-shaped output shaft. The compact 12 mm by 20 mm form factor suits small-scale mechanical builds.

Voltage range decides suitability

The motor runs from 3 V to 9 V, so it cannot be used directly with higher-voltage supplies without regulation. Buyers who need operation above 9 V or a different shaft profile must choose another motor.

Questions about this item

What does the 66 RPM rating mean once the G12-N20 motor is installed in a device?

At the rated 6 V the output shaft turns at 66 revolutions per minute, giving low-speed, high-torque motion suitable for small gear-driven mechanisms.

What does the 3 V to 9 V operating range cap in practice for this motor?

Running below 3 V may stall the gearbox; above 9 V risks overheating and premature wear, so stay within the stated voltage window.
