Answer the following statement(s) true (T) or false (F)
1. The wound-rotor induction motor and the squirrel-cage induction motor both were developed for variable speed applications.
2. To minimize the starting surge of current to a wound-rotor induction motor, insert the full resistance of the speed controller in the rotor circuit.
3. If the full resistance of the speed controller is inserted into the rotor circuit when the motor is running, the rotor current decreases and the motor slows down.
4. As resistance is removed from the rotor circuit, the rotor speed will continue to increase until its speed matches the synchronous speed of the field developed by the stator windings.
5. The starting torque output of a wound-rotor induction motor is poor when all resistance is removed from the rotor circuit.
1. FALSE
2. TRUE
3. TRUE
4. FALSE
5. TRUE
