A variable autotransformer is a single-coil transformer in which two portions of the same coil are used as the primary and the secondary. Variable autotransformers are used for the same purposes as regular transformers, but handle lower voltages.n the autotransformer, a primary voltage is connected from the bottom to a specific winding known as a âtap,â and a secondary voltage is connected from the bottom to a separate winding.
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. Other names for a VFD are variable speed drive, adjustable speed drive, adjustable frequency drive, AC drive, microdrive, and inverter.Frequency (or hertz) is directly related to the motorâs speed (RPMs). In other words, the faster the frequency, the faster the RPMs go.ther names for a VFD are variable speed drive, adjustable speed drive, adjustable frequency drive, AC drive, microdrive, and inverter.
