12V 980RPM 2.3kgfcm GM25

SPG20HP-20K is also well-known as GM25 motor, a small-size geared motor coupled with a 20:1 gearbox that is able to produce 225mN.m torque with 980 RPM (no load). It is a DC geared motor, ideal for building 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.


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.
