Sensorless Vector Control for Induction Motors
Sensorless vector control provides a more accurate estimation of the motor rotation speed
compared to V/F control. When auto tuning is completed, the inverter calculates motor speed and
does not require the rotating speed feedback from the motor. Sensorless vector control can also
generate greater torque at a lower level of current.
