In an electric drive using a three-phase induction motor, it is intended to apply regenerative braking. This is possible only if:

The rotor speed is equal to the speed of the magnetic field produced by stator currents, both rotating in the same direction.

The rotor speed is greater than the speed of the magnetic field produced by stator currents, both rotating in the same direction.

The rotor speed is greater than the speed of the magnetic field produced by stator currents, both rotating in opposite directions.

The rotor speed is less than the speed of the magnetic field produced by stator currents, both rotating in the same direction.
