<< Hi Drew,

I have a single phase, one motor speed RF-45 without power down-
feed and it does not have any kind of spindle brake. Don't know about
any of the other versions, but I never read anything in any of the
catalog specs for any version that said anything about a brake.

Drew,

Yes, now that my motor matches the spec plate, No, there is no brake on the
3 phase version either ......

Oh, I doubt you need the dynamic brake either. I needed one for a 3600 rpm
lathe spindle but I was stopping it in 1.5 seconds, five times a minute.
