In tramways which of the following motors is used ?
Correct answer: B. D.C. series motor
- A. D.C. shunt motor
- B. D.C. series motor
- C. A.C. three phase motor
- D. AC. single phase capacitor start motor
Explanation
A DC series motor gives very high starting torque and its speed naturally varies with load, making it well suited to tramway traction. A shunt motor does not provide the required starting torque characteristic.
