VFDs
VARIABLE FREQUENCY DRIVES (VFDs)
Variable frequency drives (VFDs) connect to a motor’s electrical supply and vary the frequency of the electricity powering the motor. This controls the motor’s performance and reduces the amount of energy the motor consumes. VFDs work with three-phase vector (inverter) motors in constant-torque and variable-torque applications.
