Fluctuating loads
Variable speed loads
Low torque loads
Power factor corrections
Answer is Right!
Answer is Wrong!
The correct answer is D. Power factor corrections.
An overexcited synchronous motor is a type of synchronous motor that is operated with a field current that is greater than the rated field current. This causes the motor to operate at a leading power factor, which can be used to improve the power factor of a system.
Fluctuating loads can be handled by any type of motor, as long as the motor is properly sized for the load. Variable speed loads can be handled by a variety of motors, including synchronous motors, induction motors, and variable-speed drives. Low torque loads can be handled by a variety of motors, including synchronous motors, induction motors, and stepper motors.
Here is a brief explanation of each option:
- A. Fluctuating loads: Any type of motor can be used for fluctuating loads, as long as the motor is properly sized for the load.
- B. Variable speed loads: A variety of motors can be used for variable speed loads, including synchronous motors, induction motors, and variable-speed drives.
- C. Low torque loads: A variety of motors can be used for low torque loads, including synchronous motors, induction motors, and stepper motors.
- D. Power factor corrections: An overexcited synchronous motor is a type of synchronous motor that is operated with a field current that is greater than the rated field current. This causes the motor to operate at a leading power factor, which can be used to improve the power factor of a system.
