I think maybe I've lost something in the translation in my post here.
Originally the model was listed in some spec sheets on the internet as 220v/380v (300hz/600hz); however in nailing down the price with the sales rep, I was given a spec sheet that only showed 380v (600hz). After posting my original question here, I emailed the rep that I need 220v. She said she needed to ask their engineer and got back to me later saying the engineer said they could make it in 220v. I have asked for the spec sheet for the 220v model.
[Edit] The sales rep has gotten back to me and the price is the same at $2300 and the engineer will send the spec sheet.
$2300 for an ATC BT30 7.5kw spindle motor seems reasonable from what I can tell.
If anyone sees any red flags (I am going through alibaba dot com), please let me know.
Last question... The rep stated that this 220v model will be 600hz - will I have any trouble finding a 220v 7.5kw VFD that supports 600hz?
