Replacing the 220 V DC motor on an Optimum BF Mill with an AC servo motor;
The Optimum BL20 mill was acquired by a late friend of mine, Peter McKenzie. Another friend of mine, Ockert Lombard bought it from Peter’s estate, and converted it to CNC. I acquired the converted mill from Ockert again. Although I was very satisfied with the CNC converter mill, the electronics of the 220V DC spindle motor was constantly giving problems. After some searching on the Web I decided to replace the 220V DC spindle motor with a AC Servo motor.
