Running a 3 phase machine from a singe phase supply.
« on: June 16, 2019, 03:08 PM »
Does anyone know  if more torque  on the motor will be achieved  by supplying a 3 phase  machine with electric  through a single phase  invertor?

Specifically   could I run the  Felder  K-700S  panel saw  (which has a 300mm  blade  powered by the standard fitted  4kw three phase motor)   off my 50 hertz  240 volt  single phase supply?
And  enjoy the benefits  of  more power  when sawing planks  of timber.
I just wonder  if anyone on the forum has such a set up  and how  does it perform.
Many Thanks.

If you're not a member now, you might want to join and ask on the UK Workshop forum about using a VFD to provide three-phase power from single-phase supplies.

Cheers. I might try  that.

I wouldn’t mess around with an inverter on the Felder saw unless you really know what you are doing. It’s not as simple as feeding single phase to the inverter and feeding the output to the saw. The simple, but not cheap way is to use a Phase Perfect. You could also use it to power other three phase machines if you decide to add them down the road.
