3-12V ServoCity Gearmotor

* Stalling this gearmotor could cause gear damage.

Stall Torque is the torque which is produced by a motor when the output rotational speed is zero, it may also mean the torque load that causes the output rotational speed of a motor to become zero - ie to cause stalling. Electric motors continue to provide torque when stalled. However, electric motors left in a stalled condition are prone to overheating and possible damage since the current flowing is maximum under these conditions.

If you are simply needing to operate your gearmotor from a switch, click on the picture of the switch (right).

DMSC6-16-10 small

The Digital Manual Speed Controller (left) provides proportional forward and reverse control of your gearmotor. Simply supply 6-16V to the controller and plug in your gearmotor. The speed and direction are controlled by the knob.
