Product information "12V 125RPM 0.5kgfcm Brushed DC Geared Motor"
SPG20-50K is a small-size geared motor coupled with a 50:1 gearbox. It is a general purpose DC geared motor for some simple automation projects.
The rated voltage is 12V, yet we have tried to drive this motor from 9V to 15V. 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.
For Arduino lover, get the 2A Motor Driver shield to control this motor with Arduino.
