5.10 Sensorless Vector Control for Induction Motors
Sensorless vector control is an operation to carry out vector control without the rotation
speed feedback from the motor but with an estimation of the motor rotation speed
calculated by the inverter. Compared to V/F control, sensorless vector control can generate
greater torque at a lower level of current.
