This is a Toshiba VF-Pack P VVVF-Inverter that uses power transistors. I believe it was made sometime before 1984 making it one of the first VVVF-Inverters made.
Motor Sound Rating: 10/10
When I got it I had to replace a few mounts for the circuit boards but after that I fired it up and it works great!

Ok I just released a video that shows all 16 different V/F settings which on this inverter changes how the motor sounds. You can watch it here if you are interested. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-o1VeemnoV-Q.html

strictly speaking from inverter technology point of view, we have advanced to the point that we don't need that much carrier frequency changes to achieve performance and efficiency. modern inverters use that maybe only once and are much performant than these old drives.

@@FarmYardGaming I'm afraid I have no idea ;) Such changes these days are usually down to software and I sometimes get the feeling hardly anyone knows EXACTLY what every piece of code does and it comes down to 'well.. it works, doesn't it?' Could of course just be extra wear on the brakes if they continued right down to the moment where they just had to keep braking mechanically, or just a bit more comfort by getting the mechanic brakes to kick in just a tad earlier ;) )

@@Alexander470815 Really? I really got the idea that this drive was braking the motor. Even the very old-fashioned stuff I got in education to become an electrician could do that (be it with a kind of add-on that also incorporated the braking resistors to dump the energy in to). My own motor has quite longer freewheeling runtime when power is removed, so I automatically assumed this one could do that and was doing that ;)

I once made a "fake inverter" that sounded like this, made out of an Arduino board (Esplora I think), a small inverter made of 6 small bipolar transistors and 6 diodes on a breadboard and a small motor like the ones found in cdrom drives. I you have an arduino I can send you the code. Edit : the motor is a small 3-phase alternator like the one found in crank-powered radios and flashlights (the windings have an impedance of 50 ohms)

So this one takes in 120v single phase and runs a motor on 240v 3 phase. It has an internal transformer to convert the voltage. If you care about an interesting motor sound I recommend looking for an older vfd.

It depends on the model but most likely no. This one is very old and comes like this from the factory. Newer models run at a much higher pwm frequency and sound much different. If you want to be able to customize the sound you have to build your own drive which I am working on.

La tecnología de los viejos toshiba no tiene nada que ver con la del video, usan clásicos motores de corriente continua y seguramente controlados mediante resistencias, mientras que lo del video muestra un motor de corriente alterna trifásica controlado mediante un inversor de voltaje variable - frecuencia variable, tecnología que ya incorpora automatismos como microprocesadores y electrónica compleja, por ponerte un ejemplo el subte serie 100, usan inversores con tiristores GTO de la francesa Alstom. En resumen los clásicos y venerables toshibas no tienen nada de electrónica, son pura mecánica dura y simple con muchísimos cables y relés

@yourgeekoftheweek

I will need to make a video on that but I can give you the short version. The sound comes from how the controller generates ac power. It generates a series of pwm pulses which approximates a sine wave. However you also hear those pwm pulses. The reason you hear the "gear changing" sound is due to older controllers like this one being programmed that way.
