What is a VFD? – Theory, Advantages, Disadvantages

In the world of industrial automation, a variable frequency drive (VFD) is a motor controller that is used to control the speed of motor.

Line choke is an inductance connected to the VFD input or output circuit to protect the VFD from unwanted spikes, transients, and harmonics.

In this article, you will learn why do we need to control the motion using VFD drives in industrial process control applications.

In this article, you will learn the preventive maintenance (PM) of electrical variable frequency drives (VFD).

Root Cause Analysis (RCA): Within few weeks failing weigh feeders mechanical variable speed drives (VSD).

In this post, we will understand the types of DC injection braking and their uses in a VFD (variable frequency drive).

In this post, we will see the braking theory and logic used in a variable frequency drive (VFD) for proper control of a motor.

Both soft starter and VFD can start and stop the motor but the main difference is VFD can do the speed control of motor also.

History of Variable Frequency Drives (VFD) When Tesla first introduced the 3-phase alternating current (AC) induction motor in 1888, he
