[Inductor-Recorded Traction Motor Sound モハラジオ録音] NYC Subway R142A/R143/R188 [ADtranz/Bombardier]

#モハラジオ #TractionMotorPWMSound #NYCSubway
Car Type: New York City Subway R142A, R143, R188
(The sound used in this video is from R143.)
Traction: ADTranz/Bombardier 2-Level IGBT-VVVF
PWM Pattern:
Asynchronous (250 Hz - 500 Hz) → Advanced PWM (2 Steps) → 3P → Wide 3P → 1P
Sound Characteristics:
These cars have a type of sound often heard in traction systems for the U.S. market, manufactured between the transition from ADtranz to Bombardier. Basically, it is the same as the MBTA Type 8 cars (which I posted last time), and the advanced pulse modes numbered (1) and (2) in this video also correspond to those in the previous video.
• [Inductor-Recorded Tra...
However, for NYC Subway cars, there is a momentary interruption in the early stages of asynchronous modulation where the carrier frequency rises. All car models had this kind of behavior every time during the recording. This is a behavior that cannot be seen in other manufacturers' traction system, but what kind of control is being performed here?
The AC traction PWM sound shown in this video is recorded by a sensor which is placed on the floor of a train car near its traction motor. This sensor is made by myself just using a 100mH inductor.
Due to the resolution of the spectrogram software, the frequency displayed in this video may include some error. Thank you for your understanding.
This sound is recorded in March 2019.
Sorry, I am NOT taking requests for recordings.

There are many requests for R179, but sorry I wrote that I won't take any requests, since I'm living in Japan and it's hard to record on demand. However, my fellow already recorded R179, so please watch this. kzbin.info/www/bejne/j5Wvi4uZaKx4jpY

1:18 why does it sounds cool

1:01 This is 161st Street - Yankee Stadium Transfer is available to the (B) & (D) trains Transfer is available to the Bx12 Select Bus Service

[@Wilsonthetransitfanner]

You mean the Bx6 not the Bx12

[@vibinzey]

1:24 now thats clean

[@TheSearleFamily123]

Actually the modulation pattern is Async (250-500Hz→500Hz→500-300Hz→300-310Hz)→11P(SHE)→7P(SHE)→3P→W3P→1P (SHE stands for Select Harmonic Elimination mode).

[@PmtaROBLOX]

why does it go from 500HZ to 300HZ and back to 310HZ instead of just switching right to 11P(SHE)

[@TheSearleFamily123]

@@PmtaROBLOX That again is a byproduct of how the software has been programmed.

[@domtom128]

Noob here :). Can you recommend some learning materials about these pulse modes and what does it mean that the PWM is async or sync?

[@TheSearleFamily123]

@@domtom128 Asynchronous is where it makes that wave by changing how long it pulses for between 0 and 100% but those pulses are entirely fixed or only partially moving as the wave speeds up. Synchronous is where there's a set number of pulses that are fixed to the output wave.

[@transitcity]

Wow how did you get soo deep into the propulsion sound?

[@ebaraexpress7260]

I use 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.

[@Simulation101YT]

@@ebaraexpress7260 Hi there, was looking to do the same thing. Just searched up on E.bay for a 100mH inductor. The results came up as a 2 metal pin LED-looking thing. Is this correct? Also with the TRRS cable, it looked like an AUX headphone jack with another port. Just to make sure are these the right things? Thanks in advance.

[@ebaraexpress7260]

@@Simulation101YT Hello, maybe both are OK! In UK, there are many aluminum cars, and it would be hard to catch the traction sound from them. The other noises would disturb that, but conversely this might be the sign of the recorder working correctly. Good luck!

Hey messiah im a fan but yea why R142A is crazy?

[@LinxFox]

@@richiegarcia2819 It is!

[@BurnedNoodle]

only 3 cars had that specific sound. none of the others did.

[@BJMediaTransit8516]

This sound is also the propulsion of the MBTA Green Line’s Type 9 fleet, and for fleet on MARTA.

[@EpicThe112]

To be exact the Type 8s MBTA Green Line B,C & D Branches Kenmore stop which is home to the Boston Red Sox the rival of 161st St Yankee Stadium NY Yankees AL East. This might get interesting if TTC Union Station T1s AL East Blue Jays have the same propulsion

[@TheSearleFamily123]

OK, so what's up next? I can tell you this now (I couldn't have told you before) that the actual sounds (apart from the different pitches, which relate to the transistor technology) are to do with how the motor is pulsed; it's the VVVF drive pulsing out an artificial AC wave from a DC supply. The motor is usually 3 phases, and overhead AC supplies are only single phase, so the transformer when on that voltage is AC-DC-AC. If the overhead wires or conductor rails are DC, then the transformer will just be DC-AC.

how did you make these sounds???? is it recorded??? how can this be so clear and unlike how it sounds like in train like the Sp1900 in HK with the Mitsubishi IGBT-VVVF motors

can we get FGV 3900 one? as well 4300, why? i need it for BVE sounds as we are doing some projects with trains and importing them to minecraft and we cannot find any proper sound
