Answer Posted / alacoque jean
Yes, by flux control.
Rated speed is the maximum motor speed at full torque (full load).
To increase the motor speed beyong the rated speed, one must decrease the motor flux module, with a constant feeding voltage and a maximum decreasing torque in inverse ratio of the speed.
This can be made with inverter and voltage vector control as "Field Oriented Control".
The feeding frequency increase.
