Question 32Electricity & Electronics - Assistant Engineer

The correct answer is B) series wound. Series wound DC motors are considered to produce the highest starting torque among the options provided. This is because the field winding of a series wound motor is connected in series with the armature winding, which results in a stronger magnetic field during startup when the armature current is highest. This strong magnetic field interacts with the high armature current to generate a high starting torque. The other options are less desirable for high starting torque applications. Cumulative-compound and differential-compound motors have more complex field winding configurations that do not optimize starting torque in the same way. Shunt wound motors have a relatively weaker magnetic field during startup, leading to lower starting torque compared to series wound motors.
