Invt Vfd Drives

Variable frequency drives are electronic devices that convert a (more or less) fixed frequency and voltage into a variable frequency and voltage. This devices allow electric motors to be operated with a variable speed.VFD (Variable Frequency Drives) are special systems for regulating an AC motor's torque and speed of rotation.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.
