Is the rotation direction of the motor rotor the same as the rotating magnetic field?

Is the rotation direction of the motor rotor the same as the rotating magnetic field?

For three-phase asynchronous motors, as long as the phase sequence of the three-phase AC power connected is determined, the direction of rotation of the motor and the direction of the rotating magnetic field are consistent. If the phase sequence is reversed, the direction of the rotating magnetic field will change, and the direction of rotor rotation will also change accordingly. In summary, the direction of rotation of the rotor of the electric motor is the same as the direction of the rotating magnetic field.
