6V 85RPM DC Micro Metal Gearmotor

This small yet powerful motor is a great solution for the small-sized robot. 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 small-sized mobile robots for sumo, small automation models, and of course other applications too. With the standard size and variety of gear ratios, users can always change the motor without changing the existing robot design.

This motor comes with a 150:1 gearbox attached. The gearbox output shaft is D-shaped with 9mm long and 3mm in diameter. There are several types of wheels 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.
