Welcome to the forum
Ading a detuning reactor to a critically corrected motor will shift the resonant frequency down below line frequency which is not good as when the motor is disconnected, it will slow down and pass through the resonant frequency.
The best solution is to correct ot 80% of the magnetising current only, and use a separate contactor to control the power factor correction capacitors.
