A VFD (Variable Frequency Drive), also referred to as a VSD (Variable Speed Drive), inverter or drive, is a piece of hardware that is used to control the speed of an AC Induction motor. This is achieved by the VFD controlling the Frequency output (Hz) (in conjunction...

In one word, no. A VFD cannot be used as a replacement for a voltage transformer. If a motor requires 400Vac, then a 400Vac source is required as an input to the 400Vac VFD. The same goes for other voltage classes, The only exception to this rule is with phase number....

There are 4 classes for duty classification purposes. They are: SLD – Super light duty. (startup current: 110% for 60sec and 120% for 3sec – of the FLA value) LD – Light Duty (startup current: 120% for 60sec and 150% for 3sec – of the FLA...

kW (power) alone is not sufficient. One requires the motor nameplate details and the application details. From the motor nameplate, we can find the FLA current, voltage, phase number. From the application details we can determine the duty requirements of the inverter...
