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...

Air Preheater, Superheater & Reheater simple learning. By Yuvi- Study Point

Hey everyone, today we are going to understand Air preheater, Superheater, and reheater in a simple or easy way. So, without wasting any time lets get started. Why air preheater is required? The entire heat of the flue gases cannot be recovered by the help of an economizer. So, air preheater is also required to recover some of the heat through the flue gases. The boilers efficiency is also increased by 1% with the help of air preheater. {NOTE: If you guys don't know about the economizer then go through this link which is shown below. Because in this lecture video I have properly explained the economizer in a simple way.} Economizer video link.    https://youtu.be/scxizKi7kZQ  And check out this blog if you want to simply know about it in writing. https://www.blogger.com/u/1/blogger.g?blogID=8839271828242826805#editor/target=post;postID=1907393019648483083;onPublishedMen The information about air preheaters? Now, back to the point. The ...

RVDT (Rotary variable differential transformer or transducer) simple explanation. By Yuvi - Study Point

Hey everyone, today we are going to simply learn about RVDT (Rotary variable differential transformer). So, without wasting any time lets get started. RVDT is a passive transducer which means it requires an external power source. Its designing is same as like LVDT (Linear variable differential transformer o transducer) but the main dissimilarity is that RVDT has a cam-type core or we can say rotary ferromagnetic core which means the shape of the core is different because LVDT consists or employs flexible iron core for displacement.   And by the help of shaft, this core will turn or rotate among the two windings of the transformer. The shape of an RVDT is cam-shaped. Three conditions which occur is RVDT is ~ *when the core or shaft is placed at the null position then the induced e.m.f in secondary windings are similar as well as revers in phase. E0 = E1- E2 = 0 *When the core rotates in a clockwise direction, in this the more section of the core will enter ...
