Awesome and easy to understand. I'm a mechanical engineer that deals with lots of electronics but don't have a solid understanding of the magic pixies that make up electronics. You provide an education in a way I can understand. Thank you. Wish more professors would teach like this. Reading and understanding books is a awful and slow challenge for me because of dyslexia that was never seen in elementary school (they didn't look for things like that in the 1970's). Videos help many such as myself that learn visually.

Thanks a lot for this video. Definitely appreciate you going all the way from how a motor that would benefit from a VFD works and how, internally, the VFD works, to the applications of the device itself. Much appreciated.

Thank you for this video! I've heard so many people talking about VFDs at work. I thought it would be a much more difficult concept to learn before seeing this video. It was so easy to understand! The real world example (changing frequency to a ceiling fan) helped me understand exactly what was going on! Excellent video!

Great, good deal bro. VFDs have a plethora of settings a have some with over 120, but this is a very basic intro. Besides they have a lot of internal components that might get damaged if calibrated incorrectly.

@ernestosastre7555 7 жыл бұрын

Agreed, I came to understand the DC-AC inversion and at 8:00 he makes it a lot more understandable.. Yet I don't get why the motor sees that conversion as a sinwave equivalent(and because it is dumb is not enough to account for it)

@lastnameavailableok 7 жыл бұрын

1 thing he didnt really explain is that was the on/off square wave VOLTAGE pulses to motor. Simply when you have a resistance (motor windings) and you apply voltage to a resistance, you get a current drawn by the load (motor). Because the voltage on/off pulses are so quick (microseconds, not even milliseconds), the motor cant tell that the voltage is going on and off so quick and continues to draw a near sinusoidal CURRENT and therefore rotate. As voltage stays on for more and more time, the current drawn reaches its peak, then voltage on/off time (mark/space) is reduced again, the current drawn starts to drop to zero, then the negative bus voltage is switched on to draw the negative current. The sinusoidal 'sinewave' shown over the square wave in video was the CURRENT drawn by the motor. Reducing the voltage on/off times reduces current frequency, which is directly related to motor speed, eg; 10Hz - 60Hz current draw.

@enriquecarmona6498 7 жыл бұрын

+Ernesto Sastre, it seems like the it's no longer a sine wave anymore. It's like a digital signal or binary code ( varying intensity within the - or the +) so this trick kind of fools the motor into start spinning. perhaps if I attached mi oscilloscope I'd be able to see a squarish sine signal (well sort of) genius. Hit replay and see if I make sense.

@enriquecarmona6498 7 жыл бұрын

+lastnameavailableok One 60 Hertz means that the current changed 60 times in one second + to -, back and forth. One Hertz is 1/60th of second. If the VFD was capable of handling kHz or MHz then, yes it would be thousandths or millionths of a second.

this really shines a light on to why manufactures prefer to size a motor a bit larger. if my blower motor is rated @1 inwc they often times say for reliability reasons it should be less the .7 inwc even tho its rated at 1 inwc. building on this, heat is what kills a motor and my amp draw is significantly lower at .7 I have a lot less heat and in relative terms more airflow for the given amount of heat. super cool thanks for the video. I already knew how a VFD worked but i'm happy i watched it anyways because this is key information.

@scottwillis5434 4 жыл бұрын

Great video! At the next level up, it's not "positively" or "negatively charged". The alternating voltage applied results (with a lag) in a stator current and an alternating magnetic field in the stator. The changing magnetic field induces a corresponding field in the rotor. Which is more complex, and why they are talking about charge. 😉

Very good video, however, don't forget a VFD is the most expensive way to save energy dollars on motors for a facility or home, in the end, we are talking about reducing demand charges which is the reduction in the electric bill. Reducing electric charges can be done in a number of ways 1 - Schedule the time when large motors will run, generally moving those operations to later periods say, late after to evening, 2 - hard start kits, which are a large capacitor place at the motor being started reducing in-rush draw and reducing demand on the electrical system, 3 - VFDs, however, make sure all motors with VFD's are inverter-duty or change the standard motors to ECM type which will have a cost saving also.

This explains why the control boxes for the huge ventilation fan motors at my Counties welding shop are soo big, I thought the control boxes for the fan were just for starting and shutting off the motors, then the instructor said the control boxes were for how much air is being sucked out and it senses what the air pressure in the room is, they're huge 3 phase motors maybe 20 or so HP, so how can you control the speed of huge 3p motors, with huge VFD boxes
