Can anyone help me with ideas for driving a med/large dc spindle drive motor, please?

Hi Guys,

I am trying to find out some information about driving a 7.5Kw dc motor in a bridgeport interact 1 Mk2.

This is the plate on the same motor type (taken from an ebay listing)...





The main thing here is that i have never come across this type of motor before and it has rather confused me (i thought it was just a lumpy 3 phase until i read the plate!), as well as finding info on it seems to be pretty hard too. The original driver is not working and I am trying to find out if there is an alternative way to drive this type of motor but without understanding what i am looking at, it seems impossible!

Does anyone know of A) Data sheet for this type of motor (i can't find one online but maybe I am searching wrong!?)

or B) a resource where i can find more information on how this is driven


or C) (if we have any motor specialists around here) if it can run in different ways, like using an AC drive instead of a dc drive

Any help at all here would be greatly appreciated, even if it is just "pointing me in the right direction"

Thanks,

Mort
