GEC Alsthom GTO VVVF | Jubilee Line Sound | PWM Inverter - 1996 Tube Stock Inductor Recording

The Jubilee Line is served by the Alsthom/Metro-Cammell built 1996 Tube Stock. This was designed from the 1995 Tube Stock but less developed, meaning it shipped with the very original traction inverter using the same GTO-VVVF infrastructure as the Kent Coast Networker Class 465 rather than the brand new IGBT-VVVF Onix 800. Newer train with older technology. PWM is as follows: Asynchronous 300Hz (intersective) Synchronous 21P (intersective), 15P (intersective), SHE19 (4 angle computed), SHE7 (3 angle computed), SHE5 (2 angle computed), SHE3 (1 angle computed), 1P (full wave) 00:00 Electromagnetic Recording 06:40 Natural Sound Recording 13:20 Electromagnetic & Natural Sound Noise reduction post-processing: None Equipment used: 2x 1000mH telephone pickup coil Tascam DR40X Class 365 Traction Motor Sound Class 465 Traction Motor Sound 1995 Tube Stock Traction Motor Sound 1996 Tube Stock Traction Motor Sound #induction #inductorwindingmachine #motor #vvvfサウンド #vvvfインバータ #vvvf #train
