Electrical Engineering XYZ MCQ
Which of the following DC motors has maximum relieving property:
- Differential compound DC motor
- Series DC motor
- Shunt DC motor
- Cumulative compound DC motor
Correct answer: 2. Series DC Motor
Explanation: DC series motors are known for their characteristic of developing large starting torque. This is because the field winding and the armature winding are connected in series, which allows the entire armature current to pass through the field winding. The strong magnetic field produced by this configuration results in high starting torque, making DC series motors well-suited for applications requiring a significant initial torque, such as in electric traction, hoists, and some industrial machinery.
