I think anything synchronous will automatically be louder . You can argue the increased efficiency of it has a bi produc of more sound. The scraping noise is likely just the modulation programmed to produce those odd frequencies. Its like tea pot boiling and the steam rushing out😂😂

Who makes the SynRM motors themselves? Toshiba or Mitsubishi? I heard that for previous 13000 trains, even though those had Mitsubishi drives(SiC and IGBT), the motors themselves were Toshiba.
