The modern machines have a variety of control features in order to facilitate greater accuracy, safety and productivity among all control features; in them the speed control plays a major role. To fulfil this need VFDs are used. A Variable Frequency Drive (VFD) is a type of motor controller that drives an electric motor by varying the frequency and voltage supplied to the electric motor. These days almost all industry sectors are using VFDs as a speed controlling device of Induction motors and there by the connected process.
To disseminate knowledge of VFD, Indian Machine Tool Manufacturers' Association (IMTMA) is organizing webinar on “VFD and its Industry applications”.
