Voltage symbolized “E” “V” and is
measured volts.
Volt The basic unit voltage.
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.The symbol for watt “W.
Wye connection arrangement used for the primary and/or
secondary three-phase transformer.
.
Voltage force that, when applied conductor, causes
current flow.
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.
