To reverse the direction of rotation of a three-phase motor, which action should you take?

Reversing the direction of rotation of a three-phase motor can be accomplished by reversing any two of the motor's supply leads. In a three-phase system, the sequence of the phases determines the direction of magnetic field rotation, which in turn dictates the motor’s rotational direction. By swapping any two of these phase leads, you effectively alter the phase sequence, leading to a reversal in the direction of the magnetic field and thus the direction of the rotor's rotation.

The other actions listed would not effectively achieve the desired outcome. Changing the motor winding could affect the motor's performance and characteristics but would not necessarily result in a straightforward method to reverse direction. Modifying the power supply might disrupt the power characteristics required for normal operation. Altering capacitor connections is primarily relevant for single-phase motors that use capacitors for starting or running, and would not apply to the three-phase motors in question.
