Be careful with these large series motors. Unlike shunt or PM motors they have no inherent speed regulation. Connect one to a low resistance power supply such as a battery with no load on the shaft and it can speed up until the armatures explodes.
Series motors deliver torque proportional to current and are normally current controlled.
