4 4HONEYWELL - CONFIDENTIAL File Number What is a variable frequency drive? Also known as: Frequency Converter (FC), Variable Speed Drive (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 cage motor Smooth and Accurate control Improved control over the system Cost reductions through Energy savings and improved quality

5 5HONEYWELL - CONFIDENTIAL File Number 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 of 1 year Decreases mechanical stress due to pressure spikes with direct on-line start & stop - VFDs creates a smooth start which reduces the pressure spikes that reduce system lifetime Reduces the starting current of the motor - VFDs minimize the starting current of the motor, which means electrical installation investments can be lower Save energy, increase system lifetime, save on investments
