What is Sensorless voltage vector control law (VVC) motor control model?

The sensorless voltage vector control law (VVC) is used for a constant torque profile, so the drive will deliver a constant flux up to the rated frequency.
It is based on Flux Vector control algorithm with speed regulation.
There will be a constant flux law in open loop. The speed is here an estimated speed.
