I assume it has been wound for part winding start, with the three leads for each winding being available at the terminal box, and the centre tap inside the motor. We have it connected with the 2 sets of windings connected in parallel. What I had expected was a delta wound motor with 2 leads per...
I have recently encountered a 460 volt 3 phase 200hp fan motor that was wired with 2 wye windings in parallel for across the line starting. It was wound with the centre tap of each wye being inacessible inside the motor. At the junction box there were 6 leads present, that initially led me to...
