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.
