What is a variable frequency drive? A variable frequency drive (VFD) is a type of motor controller that drives an electric motor by varying the frequency and voltage of its power supply. The VFD also has the capacity to control ramp-up and ramp-down of the motor during start or stop, respectively.
Advantages of VFD Controlled Starting Current Reduced Power Line Disturbances
Energy Savings Example: A VFD controlling a pump motor that usually runs less than full speed can substantially reduce energy consumption over a motor running at constant speed for the same period. For a 25 horsepower motor running 23 hours per day (2 hours at 100% speed; 8 hours at 75%; 8 hours at 67%; and 5 hours at 50%) a variable-frequency drives can reduce use by 45%. At ₹7.00 per kilowatt hour, this saves 53,740 units energy & ₹3,76,180 annually. Kirloskar 25 hp 3PH 1440 RPM Foot Mounted Motor ₹ 49,988
