Just finished watching your "what is a VFD?" video and, once again, the explanation was excellent, especially useful was the analogy of the water control pipeline. I started to read up about VFDs on a well-known online encyclopedia and was blinded with science. Your explanation was pitched perfectly and just what I needed as I'm working on updating our PLC to control an inverter for a water pump. Perfect, keep up the good work. Cheers!

[@ardentdfender4116]

They do lay down the fundamentals quite well in explaining things in every video fundamentally. I really appreciate that about them as well as the fundamentals help immensely in understanding and they do it in very simple explanation and animation. It’s just awesome.

[@ScabbyBoi]

Appreciate this simplified easily accessible explanation. I’m a civil engineer so I need to be familiar with the basic operation of a vfd, despite my lack of education in mechanical and electrical engineering. This video made great sense and has clarified the subject for me significantly. Thank you!!

[@realpars]

Thank you so much, @ScabbyBoi! We're glad you found it helpful!

[@jeffreyporto8113]

Thanks for the insightful comparison of electronic components to hydrologic systems . This opened a couple of doors quickly for me. To get an understanding of how a PLC interacts with a VFD has given me some confidence in my new job as a Flexographic printing Mechanic. It is my hope to not only comprehend but to be able to program fully automated six color presses to accommodate changes in production requirements across a wide variety of material and ink types. This work is gratifying and worthwhile for me and your program is now on my radar. Keep up the good work many thanks.

Dear, please share your knowledge on points 1) How to do wiring , i mean power wiring + control wiring of a VFD and its hook up with PLC 2) What are the configuration settings to be done inside the VFD for Siemens and Allenbradley ones 3) how to build a control logic for the same by using PLC programming. Kindly do the needful. You people are awesome, love u all

Exceptional video lesson with an impeccable subject of a state-of-the-art equipment which is becoming indispensable in the most varied processes. It is fascinating to understand the conversion of AC input energy into DC energy and going out simulating an AC senoid through the width of pulses having the ability to control the speed of electric motors by frequency. Thank you very much and congratulations on the excellent work. I'm from the city of Manaus, in the State of Amazonas, Brazil, country, located right in the middle of the Amazon rainforest, where incredibly there are several of these equipment, and I accompany you.

vfd controls the speed of the motor by converting AC to DC then back to AC with different frequency and it can be wired to plc to make the task automatic and get rid of a stupid operator! can't find any easier and straightforward explanation... GREAT JOB

Hi there, thanks for your comment! I will send your request through to our creator team.

[@rachidlamzougui1683]

VFD is a motor drive that controls AC motors, it converts AC into DC using a diode then it filters the current by a capacitor then converts DC into AC using a transistor. What a solid state motor drive

[@realpars]

Thank you for your question! It sounds like you’re asking about the difference between a Variable Frequency Drive (VFD) and a solid-state drive. Here’s a quick explanation: VFDs: Primarily used to control the speed and torque of AC motors by adjusting the frequency and voltage of the power supplied. Solid-State Motor Drives: A broader category that includes VFDs but also covers drives for various motor types (AC, DC, and stepper motors). These drives use semiconductor technology to control motor functions. We hope this clarifies things. Happy learning from RealPars!

So far, so good. These days, 3 phase VFD is used for most modern electric trains, and hybrid or full-on electric road vehicles, after the advent of integrated gate bipolar transistors (IGBT). Typically done with triple inverters (one for each phase), capable of working in both directions, for regenerative braking when required, using the 3 phase motor as an alternator.

At 2:20 your check valve is back to front. It would actually block water from reaching the filter.

Thank you for pointing that out. You are correct, the orientation of the check valve is reversed if the flow is from left to right.

[@Mulazim.]

Informative video! Suppose we have a traditional inductive motor with maximum 1400 RPM, then we connect that motor to a VFD, here is the question: Does it possible to increase the RPM of the same motor more than 1400 RPM by increasing the frequency? And does the power consumption will increase?

[@realpars]

It is possible to overspeed a motor by setting the frequency above the nameplate frequency. However, motor torque will start to decrease above 100% speed. This occurs because the faster speed leads to increased slip, which robs the motor of torque and converts the excess energy into heat and efficiency loss. Overspeeding a motor is sometimes done with fans, but there can be adverse effects of doing so. Power consumption depends on the loads that are connected to the motor.

[@Mulazim.]

@@realpars In my case it's a water pump one horse power 746 watts, my plan to make a basic inverter or a soft starter circuit in order to run that motor on UPS 12/220v--1200 watts,but I face problem that my UPS circuit breaker cutting off due to rough start
