I have been asked to manufacture a control panel for an automated batch
feed mixer. Pic control unit conects to weigh bridge with 8 dil relays for
auger control. My question is this, one of the motors (the first one I've looked at) has terminals marked 1,2,3 and N. 1 to 3 are the phases N has the other end of the three windings connected together. I presume this makes it connected in STAR.
Why is the terminal marked as N ? should the star point not be connected to
earth The motor does looks old
