Volts per Hertz (V/Hz) Describes the operation many variable frequency drives that
Operation control the speed motor varying the frequency of
the voltage applied the motor while maintaining constant
voltage frequency ratio.
.
Vector Control technique employed some variable frequency drives that
involves calculations motor current vectors and precise
control motor flux provide excellent speed and torque
control.
