The speed of a 37.3 kW series motor working on 500 supply is 750 rpm at full-load and 90 percent efficiency. If the load torque is made 350 N.m and a 5 ohm resistance is connected in series with the machine, calculate the speed at which the machine will rum. Assume the magnetic circuit to be unsaturated and the armature and field resistance to be 0.5 ohm.
