RE: Motor controller....IT'S ALIVE!!!

Hi Twystd,

Good Job! Congratulations!

That lovely motor looks just like the one in my R-O-K Rondine 2. This machine is just one of my projects but a three phase variable frequency drive has been in my head for some time. I like my turntables to play 78.26 and 80 RPM as well as 33 1/3 RPM. This means the motor needs to get to 4320 RPM. That would be 144 Hz. I'm pretty sure that would be no problem with your function generator. I'm pretty sure the voltage will have to go up correspondingly. I think it should be fine but it is a bit scary as these motors are not just off the shelf anymore.

When you get your notes together I would love to see them.

Phil
