Can you reverse the rotation of any three-phase motor by interchanging any two of the three power supply lines?

Interchanging any two of the three power supply lines in a three-phase motor is the correct way to reverse the motor's direction of rotation. This principle is based on the way three-phase power systems work: the sequence in which the phases are connected determines the direction of the rotating magnetic field within the motor. By swapping any two of the three phases, the sequence of the magnetic field's rotation is reversed, which in turn reverses the motor's rotation direction.

This method applies universally to standard three-phase induction motors and is a fundamental aspect of motor control in industrial applications. However, this principle does not typically apply to single-phase motors or specific types of motors that may have unique wiring or operational characteristics.
