Metals Fans, pumps
Variable frequency drives (VFDs)
regulate motor speed to control the
flow and pressure of blowers or pumps
without dampers or throttling valves.
This results in energy savings and no
output waste. VFDs also provide a soft
start to the motors, reducing the stress
on driven load and resulting in lower
maintenance costs.
A VFD manages power based on actual
demand and uses only the energy
required by the driven equipment to
provide valuable energy savings.
When starting large motors with VFDs,
current inrush peaks are eliminated.
The VFD gradually ramps the motor
up to speed by varying output voltage,
current and frequency for a soft start.
