12V 580RPM 3.5kgfcm GM25

SPG20HP-34K is also well-known as GM25 motor, a small-size geared motor coupled with a 34:1 gearbox that can produce 3.5kgfcm torque with 580RPM (no load). It is a DC geared motor, ideal for building a small-sized mobile robot 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.

The rated voltage is 12V. 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.
