Honestly there arent any that I can really think of, I know there are a few, maybe flashcut, but I would go with the gecko drives.
I was able to run 5000hz on these motors at 30v and very strong, I tried 10,000hz at that voltage and it couldnt quite handle it, but on 60v Im sure it can handle 12000hz or more wich would calculate to about 70-80ipm on 5tpi ballscrew
