VFD (Variable frequency drive) control panel simple explanation. By Yuvi - Study Point

Hey everyone, so today we are going to learn about VFD (Variable frequency drive) control panel in a simple or easiest way possible.
So, without wasting much time let's get started.

  • VFD (Variable frequency drive) control panel. Now, the questions arise.
 What is the VFD (Variable frequency drive) control panel?
  • As the name suggests it is something like Varying the frequency.
  • So, the VFD drives an electric motor by varying the frequency & voltage supplied to the electric motor or of its power supply. And it is a motor controller.
  • Its other names are or we can say it is also known as adjustable speed drive, adjustable frequency drive, inverter, microdrive, AC drive, and variable speed drive.
  • So, these are the other names of the VFD (Variable frequency drive) control panel.
  • The motor's speed is directly related to the frequency or Hertz or in simple words we can also say that they both are directly proportional.
  • Which means the faster the frequency, faster will be the motor's speed or the faster the RPM'S go.
  • During motor's start or stop respectively the VFD also has the capacity to control ramp up or ramp down.
  • We can simply say that if the speed requirements of any system changes then to meet the speed requirements of this system or application, the VFD can simply turn up or turn down the motor's speed.
  • For example, ~ VFD can be used to ramp down a system which does not require an electric motor to run at full speed.
  • As in this case, VFD can simply ramp down the frequency and voltage to meet the speed requirements of an electric motor's load.  
Now, the question arises what is VFD control panel used for? or why we use VFD panels?
  1. VFD (Variable frequency drive) control panel is used for power switching as VFD's are installed with a circuit breaker so it can easily turn on or off the power and because of this, we can say that it is also used for protection.
  2. VFD panel has a display and operational panel so it becomes easy or convenient for the operator to control the motor as the VFD control panel can display the panel's operational status visually.
  3. VFD control panels are used because it is a complete motor control solution (harmonic filtering, bypass, etc).
  4. VFD's are essential because we can keep all the components in one panel.
  5. VFD control panels keep weather, dust, dirt, etc out of electrical parts.
So, these are some of the reasons, why we use VFD (variable frequency drive) control panel.

Application

VFD control panels are widely or we can say mostly used in pumping, drilling, and other large machines applications.

NBFM & WBFM (Narrow band frequency modulation & Wide band frequency modulation) simple explanation. By Yuvi - Study Point

Hey everyone, today we are going to learn about NBFM & WBFM (Narrowband frequency modulation & Wideband frequency modulation) in simple or easy way. So, without wasting any time lets get started. The information about NBFM & WBFM When the spectrum's efficiency is important or it is required then we use NBFM (Narrowband frequency modulation) is used.  But when better signal quality is required or when it is important then we use WBFM (Wideband frequency modulation). The term NBFM is used for those applications where the modulation index is less than or equal to 1. And the term WBFM is used for those applications where the modulation index is greater than or equal to 1. Now, let's see more difference between Narrow band frequency modulation(NBFM) and Wideband frequency modulation(WBFM). The term narrow-band and wide-band refer to the actual radio channel bandwidth. The purpose or advantage of using NBFM (Narrowband frequency modulation) The purpo...

Corona effect in transmission lines.| Explanation by Yuvi - Study Point

You all have heard about the Corona effect in transmission lines, now understand it in a simple way. This effect is a phenomenon which is associated with all transmission lines. At certain conditions, the electric field closer or near the energized conductors or components produces a tiny electric discharge or we can say corona which causes the surrounding air to ionize. And due to this ionization of surrounding air molecules of conductors, a luminous glow with hissing noise is produced which is known as Corona effect. Between the transmission lines, air act as a dielectric medium or we can say that air act as an insulator between current-carrying conductors. Between the conductors, voltage induces and if this voltage is of alternating nature then charging current will flow between the conductors. And the voltage of this transmission line and electric field intensity increases because of this charging conductor. There is a predetermined value of the electric field inten...

Difference between Alternator and Generator. By Yuvi - Study Point

Hey everyone, today we are going to see the simple difference between Alternator and Generator. So, without wasting any time lets get started. Alternator   An alternator is a machine that converts mechanical energy from a prime mover into the A.C electrical power at a specific frequency and voltage. Alternator induces an alternating current. The input supply in the alternator is taken from the stator.  The alternator has a variable output e.m.f. The alternator is smaller in size as compared to the generator and that's why it requires less space as compared to the generator. The output of the alternator is higher than the generator. The alternator has a wide range of rotation per minute (RPM). The armature of an alternator is stationary which means in an alternator, electricity is produced when the magnetic field spins inside the stator (winding of wire).    The alternator has a rotating magnetic field. A dead battery is can't be charged by an alterna...
