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. Other names
