What is a variable frequency drive?
Also known as: Frequency Converter (FC), Variable SpeedDrive (VSD), AC Drive, Inverter etc.
A squirrel cage motor is
the typically used
electrical motor in
industry and public
engineering sector
Stepless control
for the speed of a
squirrel cagemotor
Smooth and
Accurate control
Improved control over
the system
Cost reductions through
Energy savings and

Why use variable frequency drives?
Saves energy through fan and pump speed control
-up to 70% energy savings in pump and fan applications
e.g. 32% average savings in a ventilation system Payback period of1 year
Decreases mechanical stress due to pressure spikeswith direct on-line start & stop
- VFDs creates a smooth start whichreduces the pressure spikesthat reduce system lifetime
Reduces the starting current of the motor
- VFDs minimize the starting current of the motor, which meanselectrical installation investments can be lower
Save energy, inc rease system l i fet ime, save on in vestm ents
