Stall Current. From the Wikipedia page on Stall Torque : Stall torque is the torque which is produced by a device when the output rotational speed is zero. It may also mean the torque load that causes the output rotational speed of a device to become zero-i.e. to cause stalling.Stalling is a condition when the motor stops rotating.rom the Wikipedia page on Stall Torque : Stall torque is the torque which is produced by a device when the output rotational speed is zero.
