As shown in figures "A", "B", "C", and "D" of the illustration, what is the usual means by which the rotation direction of the motor is reversed? Illustration EL-0207
AI Explanation
The correct answer is D) Interchanging leads T5 and T8.
The usual means of reversing the rotation direction of a motor is by interchanging the leads T5 and T8. This swaps the connections of the start and run windings, which reverses the direction of the rotating magnetic field and thus the direction of rotation.
The other options are incorrect because:
A) Interchanging L1 and L2 would only affect the power supply, not the winding connections.
B) Interchanging T1 and T5 would not reverse the rotation.
C) Interchanging T4 and T8 would not properly swap the start and run winding connections.
