This small yet powerful motor is a great solution for small-sized robots.

We have been carrying the SPG10 Micro Metal Gearmotor for quite some time and it has served the makers community well. Many are using it to build the small-sized mobile robot for sumo, small automation model and of course other application too. With the standard size and variety of gear ratio, users can always change the motor without changing the existing robot design.

This motor comes with 298:1 gearbox attached. The gearbox output shaft is a D-shaped with 9mm long and 3mm in diameter. There are several types of wheel that you may use together with this motor.

The nominal voltage is 6V, yet we have tried to drive this motor from 3V to 9V. Lower voltage might not have enough torque to drive the wheel or mechanism; higher voltage will provide higher torque and higher speed, but it will shorten the life of the motor.

Q & A (6)
So my max load is roughly 10kg, so the radius of my wheels should be approximately 6cm correct? ( Amy Lim, 25/01/2022 )
Hi, its depends on your wheel position and robot design. 
hi, may i know it is ready stock? can ship out in this few days? ( wee, 13/04/2020 )
Hi, yes we do have ready stock now and we do process and deliver during this MCO period. But, do expect some shipment during this period. We will try our best to ship out as soon as possible. Thanks :)
How to buy in bundle?when i enter 40 & 50 pieces the price still rm19.61?not as stated above..10 or more RM18.0450 or more RM15.69 ( Kin , 02/03/2018 )
You can add to cart first and the price will change :)
hi can this motor take a load of 1kg? ( mr chan, 25/09/2016 )
Hi, Stall torque, 6V: 1.8kg-cm (Approximately= ~0.177N.m).  Yes, you can use it. But you need to measure the distance between the motor and the load only 1cm/kg. If you have further question, you can ask at our technical forum, as this session is only for short inquiry. Thanks. :)  
Hi, is this able to drive a model with crankshaft which weight around 1kg? ( MCLim, 11/04/2016 )
Hi. It is depend to the design. But the torque for this motor is 1.8kg-cm. Thanks. :)
