AC servo motor help !

[vre]

Hello to all!
I have a similar problem.. but with one advantage i have 3 phase 400V (not 3phase 230V servo needs)..

In europe the mains power supply is 230V 1 phase / 400V 3 phase 50hz.
I got a 3 phase servomotor + 3 phase servodriver 1.8kw 220V and i have to my house 1 phase 230V and 3 phase 400V what can i do to connect this servo ?
3 phase transformer from 400V to 230V would be ok ?
Can i run it from 1 phase 230V without transformers ?
The driver inside has 3 big 420V 270uf rubycon MXG(PET) capacitors ..
To use single phase supply without transformers If i add 3 same caps in parallel and connect phase to L1 terminal of driver neutral to L2 terminal and phase again to L3 will be ok ?
Can you help me ?
thank you.

Yes, but probably a bit expensive?

Can i run it from 1 phase 230V without transformers ?

To operate with single phase continuously at the rated power you would need three times the capacitance - so an extra 1620uF. Keep the wires from the new capacitors to the existing ones short. Also check the current rating of the rectifier.

Bear in mind that if you're not using the servo drive near it's rated power, you may well be fine leaving it as it is. Have you tried contacting the manufacturer about operating on single phase? They might have already included enough capacitance to work with single phase.
