Apologies if this question is misplaced, but I am sure several people here know the answer.
I've have a Swiss 3-phase 1/2 HP 50Hz motor from the 1960s, marked 380/220V on the nameplate. I believe that it's currently set up for 380V 3-phase but wanted to confirm that.
- In the connection box is a label which (translated from German) reads: "Attention: for star connection the star point of the motor windings is behind the connection box."
- In the connection box, the three phase supply is attached to three motor wires labeled U, V, W.
- Behind the connection box are three more motor wires labeled X, Y, Y that are all tied together with a blue crimp connector. I suppose that this is the "star point" of the motor windings as per the label.
Could someone here please confirm that the way it is now wired, with supply connections to U, V, W is indeed the 380V three-phase variant? Or if not, advise me on how to reconnect the wires?
Cheers,
Bruce
