Spindle motors resonable options

[blackburn mark]

have a look at my build log, iv made three to cover the whole speed range, they are not full proven (bearing life etc) but they do work quite well and are easy and cheap to make
jonathan may at some point work out an interface with mach for these type of spindles

I'd forgotten about that, sorry! I will look into doing it again with that servo controller soon.

I've got a bit closer with my brushless motor spindle. The chuck and ER16 collets finally arrived yesterday.
(Edit - if you saw the comment with regard to running it from VFD ignore it)

Still got to get a 12s 100A ESC for it and something to power it. Best I've got is a 6s 100a and 24v 92Ah VRLA battery. That'll get 3000rpm - so enough for some things.
