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.
