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.

The Precision Digital Speed Controller (left) will allow you to control your gearmotor with a servo controller (options shown below). This combination will allow you to precisely vary the speed of your gearmotor both forward and reverse.

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.
