single phase compressor motor

[Griffey]

Hi, I am looking for a connection diagram or sugestions for a 2.2Kw single phase motor to drive a compressor. The spec plate shows that it can be run at 220-240 v / 460-480v 50Hz. (unusual for 50Hz) At 220-240 volts FLc is 16A plus startup inrush. so I should like to run it at the higher voltage as I have 400v available at the 3 phase DB. I can't find anything on the web not even Brook motor website. Any help would be appreciated. Not come across this motor variant before, see pict below!
Thank you Griffey!

400v is a considerable drop.

It's designed to be suitable for normal 230V single phase or 460V single, split phase. This supply arrangement is fairly rare in the UK generally, but is very common in the area I live and work. I've fitted loads of these motors over the years.
The motor would run on 400V taken from 2 phases of a 3 phase supply, but will be down on power.

Hi, Thank you for the information, I'll stay with the 230v connections as it's not a good idea to run a compressor under voltage. Are you situated in the USA? re the split phase comment!

No he is based in the UK where there are split phase supplies (460v between lines). Whether this motor was produced for UK use or the States where 460-480v is common who knows.

Hi, Thanks for that, you learn something new almost every day!
