Discussion Post: Equivalent Circuit & Speed Calculation

The magnetization curve of a 2-pole, 100V DC shunt motor at 2200 rpm is given below. The armature resistance is 0.12Ω. The shunt winding has 500 turns per pole and its total resistance is 125Ω. Full load current is 40A. Since the motor has a compensation winding, the effect of the armature reaction is neglected. The total rotational losses of the motor (Pfe+Pfw) are 240W: Using the given values;

1. Draw the equivalent circuit of the motor. Find the speed of the Motor at full load.
2. Calculate the speed regulation.
3. Find the shaft torque and efficiency of the motor.
