Which of the following motors is used in a situation where load increases with speed ?
Correct answer: B. Three-phase series motor
- A. Induction motor
- B. Three-phase series motor
- C. Schrage motor
- D. Hysteresis motor
Explanation
A three-phase series motor has a characteristic suitable for applications in which the load torque rises with speed, such as traction-type duties. Its series excitation gives high torque and a speed response different from ordinary induction motors.
