Question 277Electricity & Electronics - QMED

The correct answer is A) Any two of the "T1, T2, and T3" leads are reversed only. In a wound-rotor induction motor, the direction of rotation can be reversed by reversing any two of the three "T1, T2, and T3" leads that are connected to the rotor windings. Reversing these two leads changes the direction of the rotating magnetic field, which in turn reverses the direction of the motor's rotation. The other options are incorrect because: B) Reversing the "M1, M2, and M3" leads (which are connected to the stator windings) will not reverse the direction of rotation. C) Reversing both the "T1, T2, and T3" and the "M1, M2, and M3" leads is unnecessary to reverse the direction of rotation. D) It is possible to change the direction of rotation of a wound-rotor induction motor by reversing two of the rotor winding leads.
