220 volt BLDC motor

<< < (4/4)

H.O:
I haven't seen Openinverter project before but it looks to  me as if it's designed for induction motors - ie it's a variable frequency drive with V/f control like any normal VFD and so is not suitable for permanent magnet motors.

I took another look at the motor on my lathe and it's aproximately 90mm square/round(ish) and 125mm long so a slightly larger than the 1100W version mentioned. I'll give it the benefit of a doubt but if/when it fails I'll replace it with something like a 130ST-M10025 from AliExpress.

They also run at an extra low voltage, so will need big, chunky cables and there might not be room for them.

It can also work with permanent magnet motors like the ones salvaged from EVs.

That open inverter thing looked interesting until I looked at the price. :eek:

Too many features that I don't need I think.

I am sitting here wondering if these 36 volt 500 watt controllers that I have lying about could be driven into a transformer and then into the 220 volt BLDC motor. Timing would be a bit strange but the Hall feedback should compensate.

I ordered this one:

It's open source, build your own!
