  I actually attempted to record it, though it is quite hard to do it because of the noise by the inverter and the overhead power lines. Additionally, there are already recordings out there.

  hello ¿the stadler flirt class 745 EMU of the greater anglia are equipped with ABB BORDLINE IGBT-VVVF?

  I would assume so. Stadler uses (from what I know) ABB all the time for the FLIRTs they produce.

  That driver certainly worked a lot on the brake there^^ The last part sounded suspiciously like "direct-self-control" to me, but it would've been the first time I'd see it from standstill... Unfortunately there doesn't seem to be a lot of info around for this...

• 
  @firetraxxms47 ай бұрын

  Yeah unfortunately there isn’t much about this train‘s inverter… I also assume that the driver behaved like that because it was very wet and slippery on the rails and some modulations might come from wheel slipping… The last part is in fact the „Asynchronous 550Hz with Random Carrier Frequency Modulation (RCFM), which can sometimes look and/or sound like DSC as you described.

  Do Talinns' CAFs are equipped with CAF IGBT inverters?

• 
  @firetraxxms48 ай бұрын

  The CAF trams in Talinn (from what I’ve read on Wikipedia) seem to be Urbos trams as well (Urbos AXL). So I would assume they have CAF-IGBT inverters as well, but I‘m not sure. CAF is (as far as I’m aware) known for not using their own inverters like the CAF MA300 for the Rome Metro, which uses Bombardier-IGBT, or the NS SNG, which is a CAF Civity with a Mitsubishi-SiC inverter. Additionally, CAF often utilises the Direct Self Control (DSC) and/or Direct Self Regulation (DSR). The DSC on the Urbos 3-100 is audible in real as well, although it’s quiet. My suggestion is to listen for DSC/DSR, that usually comes after the Asynchronous part, to have at least an indication, that it could be a CAF-IGBT inverter. I hope I could help a bit.

  @@firetraxxms4Most CAF Urbos trams use inverters from CAF Power & Automation. That company was created by acquiring propulsion manufacturer Trainelec. Many of their full size metro trains, EMUs and other trains now use those products also. A few examples of CAF (Trainelec) propulsion in a heavy metro setting would include the Caracas Metro and Bucharest Metro. As for motors, CAF typically specifiies those components from Traktionssysteme Austria (most recent projects including Urbos trams) or ABB.

  @TheSearleFamily123 Жыл бұрын

  I think the interference is actually caused by the aluminium body, which does make inductor recording hard.

  Isn’t the body connected to ground? I mean the noise varies, depending on how I position the „inductor“.

  Can I give two suggestions of inductor recordings? Both use adtranz vvvf. For Italy, e.464 AND for germany, BR423. Thanks from Brazil.

• 
  @firetraxxms4 Жыл бұрын

  Hey. For the BR423, it isn’t possible to record due to the very loud H-Bridge noises which makes the actual sound inaudible. For the FS E.464 it’s unfortunately not possible to record it because it’s a locomotive and I have no access to go there and record it. I’m sorry for not accomplishing your suggestions.

  Hey! Which electronic parts did you use to record, two 100 mH coils, one for each channel? And what do you mean by H-bridge sound, and what could be done against it? And which recorder did you use? I'd be very happy if you could answer my question 😀 I'm another train sound lover!

• 
  @firetraxxms4 Жыл бұрын

  Hey. It’s actually written in the description about the recording equipment. With the H-Bridge noises I mean the other noise generated by the inverter that messes with the Inductor and as of now, I don’t really see any way to get rid of this noise because the inductance might be over 100mH and it’s really sensitive to any other electric noise. I hope this answers your question (:
