I just love the ADTranz/Bombardier traction motors. Going to miss the M-4s btw. Very problematic with the Broad Street Line cars (Kawasaki SMEEs) outliving them.
I can't tell if this is GTO or IGBT. On the one hand, it sounds remotely like the Adtranz GEATRAC GTOs on the Hong Kong MTR A Trains and the Berlin S-Bahn Class 481. But at the same time, it sounds like an early version of the IGBT-VVVF MITRAC system installed on the R142A/R143/CQ312/MBTA Type 8. What might help is if the motors on the M4s related to the 1507/1508 Series motors used on the latter trains and the refurbished BART cars?
The trains in our city, namely series 2-5 of the ET 423 of the Deutsche Bahn, have a similar inverter, also made by ADTranz, just with 420 Hz being the carrier frecuency for the whole asynchronous section without it dropping down to 280Hz, though the rest sounds the same. Now I just need to find something that sounds like the first series with the GTO inverter :P
I recorded that IGBT one before! Yes, they use close frequency value for the beginning, but after that they spread the spectrum in a complicated way and that sounds so weird. This feature can also be seen in other ABB / ADTranz tractions, such as CPTM 2000 Series.
I noticed as well that most german trains made by siemens have that same "klang" thing, such as the BR423 BR101 or BR146 etc, If you have more explanations on why they sound like that I'd be happy to hear that, I love these sounds
I don't create these sounds, just recording with an inductor (100 mH), a TRRS cable, and an IC recorder. I record these sounds by putting this on a train car's floor just above its traction motor.
I use “WaveTone” for the spectrogram, and the video editing software “AviUtl” for the waves shown below that. Unfortunately these are Japanese softwares, so it might be inconvenient for you to use.

This is a great recording. I've always loved the sound of the M-4s!
Same 😂
same
the first part of it is highly accurate of the first showcase

This train motor sounds interesting! I like it.
The second file also has a long time for cruiseing and the when the motor starts
The difference on number 2 is that it stays in 1 pulse mode when allceleration and the cruise
あああ… 良き… ❤️
次はBARTお願いします！
後、グッジョブです！
Actually the synchronous pattern is 8P→7P→5P→5P (CHM)→3P→W5P (CHM)→W3P→1P (CHM stands for Current Harmonic Minimum mode).
Do you know what the omitted phase is?
@@GamerRobYT Could be synchronous 9-pulse mode, but I don't know for sure.
I believe these are IGBT actually. they resemble the singapore C380C units I believe.
can you do a Bombardier R179 please?

Can u try looking under the cab for this train for anything that resembles a horn I wonder what type of horn does the m4 use
its very squeaky and high pitch. i prefer the wabco aa2 of the kawasaki b4

@@phox4186 Someday, I'll show you the spectrum of the BR 423 IGBT's sound!
They spread the carrier frequency in a strange way.
@@ebaraexpress7260 I am looking forward to see that :D
Can You Do NJT Arrow III VVVF Please?
Yes
What do you use to make the sounds?
I don't create these sounds, just recording with an inductor (100 mH), a TRRS cable, and an IC recorder.
I record these sounds by putting this on a train car's floor just above its traction motor.
@@ebaraexpress7260 oh ok thank you
apart from the inductor what software do you use for the sound/piano?
I use “WaveTone” for the spectrogram, and the video editing software “AviUtl” for the waves shown below that.
Unfortunately these are Japanese softwares, so it might be inconvenient for you to use.
Do one for the Arrow III
Do m9 train
Speed
