These brushed DC gearmotors are compact and affordable — perfect for building a quick, miniature robot. They are intended for use at 4.5 V, though in general, these kinds of motors can run at voltages above and below this nominal voltage, so they should operate comfortably in the 3 V to 6 V range. The plastic gearbox is protected by a built-in safety clutch that will typically slip before the gear teeth can shear.
Specifications
- No-Load Speed (6V): 200 RPM (±10%) @ 0.2A
- No-Load Speed (3V): 90 RPM (±10%) @ 0.15A
- Maximum Efficiency: 2.0 kg-cm / 170 RPM / 0.6A
- Reduction Ratio: 1:48
- Can be used with our Arduino and Raspberry Pi boards

What voltage should I use for this motor and what range is supported
The motor is intended for 4.5 V nominal operation, but it can run from about 3 V to 6 V depending on load.
What is the gear reduction and the no load speed at different voltages
The gearbox reduction is 1:48. No load speed is about 200 RPM at 6 V (0.2 A) and about 90 RPM at 3 V (0.15 A).
How much torque and efficiency can I expect
Maximum efficiency is 2.0 kg cm at about 170 RPM with 0.6 A.
Is this motor compatible with Arduino or Raspberry Pi and are there tutorials
Yes, it can be used with Arduino and Raspberry Pi boards and tutorials are available.
What safety features exist and how should I perform maintenance
The plastic gearbox is protected by a built in safety clutch that will typically slip before the gear teeth shear, protecting the gears. Operate within the voltage range and avoid overload to help longevity.
