Thanks for explaining that m_c
To anyone ,will this be sufficient running my spindle motor http://cgi.ebay.com/ws/eBayISAPI.dll...tchlink:top:en I would also use a braking circuit.
spoke to the seller yesterday and says the drive will be about 140v output due to 10-12% power loss on the bridge of the drive

But im unsure what determines a drive works with a brushed motor and not brushless and vice verser
some state there for one or the other and others don't mention it, my motors brushed .

That drive should work. However you need to ensure you have an incremental encoder, that outputs a quadrature signal (usually referenced as A & B outputs). You'll need to figure out eaxctly what the existing feedback device is, to see if it'll be any use.
