VFD 3-Phase Drill Press Upgrade:

  I have always loved our little drill press, but low speed is never low enough and moving the belt is annoying. On a previous project, I became aware of the WEG CFW10 variable frequency drives and that is where the idea for this upgrade was born.

  The model I used on this project ( CFW100040SAPLZ )takes a 110V single-phase supply and outputs three-phase 230V power to the new three-phase 1/3 horse motor.

  The first step  (shown in the pictures above), was to adapt the new motor to the old bracket. Slotting a couple of existing holes, milling a small clearance pocket, and drilling a new hole for the shaft is all it took to get the new motor on the old machine.
