I have a Beaver turret mill with a single speed, 3 phase motor running on 380v, 50Hz.
As far as I know (but I may be wrong), it's delta wired. If this is so, would wiring it in star configuration reduce the motor's speed? I'd like to be able to run the spindle slower than 70 rpm, without buying a variable speed drive.
Anyone know if this can be done? Snags?
