A 230V shunt motor having an armature resistance of 0.05 W and a field resistance of 75 W draws a line current of 7 A while running light at 1120 rev/min. The line current at a given load is 46 A.
A 100V dc series motor has an armature resistance of 0.2 ohm and field resistance of 0.25 ohm. The motor runs at a speed of 600 rev/min when the shaft torque is 27.14 Nm. Friction and windage losses at this speed are 300W.
