strictly speaking from inverter technology point of view, we have advanced to the point that we don't need that much carrier frequency changes to achieve performance and efficiency. modern inverters use that maybe only once and are much performant than these old drives.
@@frommarkham424oh, my bad, I kinda thought they all had them... Edit: it would be cool if electric cars had the same acceleration and deceleration sounds as electric trains. I think it's impossible tho...
Actually it is for passenger comfort. Since we are railway fans, we love the sound of trains, but for a passenger whose purpose is only to "travel from point A to point B" it will be annoying, especially on long trips (This also happens with car fans)
my guess would be on efficiency. every bit of energy, that does not go towards it's intended use, means worse efficiency. and especially with electric cars, that fight for every kilometer of range they can get, even this could be a power saving measure
Oh I didn't build this but got the motor and inverter used. However I plan on making an inverter where you can customize the sounds. I will post that once I get it working.
I once made a "fake inverter" that sounded like this, made out of an Arduino board (Esplora I think), a small inverter made of 6 small bipolar transistors and 6 diodes on a breadboard and a small motor like the ones found in cdrom drives. I you have an arduino I can send you the code. Edit : the motor is a small 3-phase alternator like the one found in crank-powered radios and flashlights (the windings have an impedance of 50 ohms)
what actually emits the sound, is it from the inverter itself, or the electric motor resonating? as in, which thing here is shaking the air that we hear?
So this one takes in 120v single phase and runs a motor on 240v 3 phase. It has an internal transformer to convert the voltage. If you care about an interesting motor sound I recommend looking for an older vfd.
It depends on the model but most likely no. This one is very old and comes like this from the factory. Newer models run at a much higher pwm frequency and sound much different. If you want to be able to customize the sound you have to build your own drive which I am working on.
That's cool your making a game! Sure! You can use the sound. Just mention my channel. Although I am probably going to make another video about this VVVF inverter soon because there are different settings that change the sound a bit.
I will need to make a video on that but I can give you the short version. The sound comes from how the controller generates ac power. It generates a series of pwm pulses which approximates a sine wave. However you also hear those pwm pulses. The reason you hear the "gear changing" sound is due to older controllers like this one being programmed that way.

The R211 uses asynchronous PWM when it starts which has a constant tone but as it speeds up it switches to synchronous PWM which sort of sounds like gear changing. This inverter only uses synchronous PWM.
@@I.NSORGE This model is the Toshiba VF Pack P but it is a special 110v input model that I have not been able to find again. But you can find something similar by searching Toshiba transistor inverter ESP130. It may not sound like the one in the video though. Make sure to check the input and output voltage. Also keep in mind some models are single phase input and others are three phase input.
Actually oldest metro trains in Helsinki Finland has still one of the oldest VVVF-inverter there is. Model is from 1977 th-cam.com/video/pNezFpOrR-M/w-d-xo.html
Using GTO modules would require a complete change in driver circuitry to use since this inverter uses power transistors. Actually, the type of semiconductor switch does not affect the sound at all. It is all comes down to programming. The reason why most inverters with GTO inverters sound like they do is because they cannot run a high frequencies.
