Chapter 34, Problem 1SQ
What characteristic of wound rotor motors led to their wide use for industrial applications?
Expert Solution & Answer
To determine
State the characteristics of wound rotor motors that led to the wide use for industrial applications.
Answer to Problem 1SQ
The speed or torque control characteristics of wound rotor motors are led to the wide use for industrial applications.
Explanation of Solution
The wound rotor motor is the first AC motor provided with the speed control characteristics. The wound rotor motor is widely used in industrial power applications since it provides the wide range of speed control. In addition, wound rotor motor has features of high-starting torque and low-starting current. These features are highly necessary to provide the motor better operating characteristics to use for applications where a large motor is required or where the motor must start with load connection.
Conclusion:
Thus, the speed or torque control characteristics of wound rotor motors are led to the wide use for industrial applications.
