Variable Frequency Drives – Everything about VFDs by ElectricalEngineering.XYZ

Variable frequency drives are the high-power circuits that are designed to produce varying frequencies by which they provide useful power over a wide range of speeds for an AC motor to run. This article briefly explains the working of VFDs and its practical applications and working. Synchronous speed, frequency, and poles of the induction motor … Read more

Basics of Stepper Motor

A stepper motor, also sometimes referred as step motor or stepping motor divides the full rotation into a number of equal steps. In this article you’ll learn the fundamentals of stepper motor. A stepper motor is a “digital” version of the electric motor. The rotor moves in discrete steps as commanded, rather than rotating continuously … Read more

How to Start Three Phase Motor on Single Phase Supply

Question: How to start a three-phase motor using Single phase supply? The single phase should be supplied to the pair of winding simultaneously with a start capacitor in series with the third winding. The figure below illustrates the circuit configuration of the process: A switch is added with the start capacitor and is opened upon … Read more
