Variable Frequency Drive Working Principles
An AC motor drive is a frequency converter designed to control the speed and torque of an electric motor – typically 3-phase AC induction or 3-phase BLDC motors – using specifically developed control methods such as Variable-Frequency Drive (VFD) or Field-Oriented Control (FOC). Variable Frequency Drive Working Principles A variable frequency drive (VFD) consists of three main elements: an AC motor (usually a 3-phase induction motor), a drive controller and a user interface . The AC motor The AC drive controller The AC drive interface AV Drive In Industrial Application The advent of powerful semiconductor controllers has enabled a new class of industrial drives to be developed around AC electric motors, specifically using a variable-frequency drive (VFD). This has allowed many applications that previously required a DC motor with pulse width modulation for the accuracy to use more power-efficient three-phase AC induction motors instead. T...
