Hello
I'm upgrading my 2.2kw spindle and VFD to Fuling 5.5kw vfd and 4.5kw er32 3 phase spindle.
I am debating the cable size from VFD to spindle.
The spindle motor plate states 3 phase 380v 9amp. Its 3 phase into the VFD and 3 phase out to spindle.
So would 16awg (1.5mm2) 4 core shielded be suitable- what would you use?
If so,can any one recommend a supplier for 8m?
thanks
Al

1.5 should be fine, as 9A is within the ratings I can find (vary from 10-19A) depending on application, and I very much doubt you'll be making full use of the 9A constantly.
Personally, for something that's flexing a lot, and with the potential to cost money should it fail, I'd spend the extra money and get some ChainFlex cable from Igus - https://www.igus.co.uk/chainflex/motor-cables
Standard ChainFlex CF885 Motor is £4.02/m or £3.27/m if you buy more than 10m, although that has no oil resistance.
If you want Oil Resistance, then look at something like CF30Avoiding the rubbish customer service from AluminiumWarehouse since July '13.
