Voltage force that, when applied conductor, causes
current flow.
Watt The basic unit electric power.
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.
Voltmeter meter designed measure voltage.
