U1 v1 w1 colours. How do you know if the copper links between u1 v1 w1 and u2 v2 w2 on a dol motor are to be installed vertical or horizontal. From this triangle diagramwe can determine the correct phasecable termination for right terminal and the rotationas we knowthe star. L1 and l2 go between u1 and u2 l2 and l3 go between v1 and v2 and l3 and l1 go between w1 and w2. Change direction in clockwise 1 r phase connected to u1 w2 r phase connected to u1 v2 y phase connected to v1 u2 y phase connected to v1 w2 b phase connected to w1 v2 b phase connected. For detail about star delta stater please read my last post about it. L1 goes between u1 and u2 i dont think so from recent experience but my understanding of 3 phase motors would have each winding as a single.

The rest u2v2 and w2 will be at the star pointnow u can mark as u2v2 and w2 at the other ends of each u1v1 and w1if u know about phase sequence very well u will find that motor terminals are not importantimportant thing is which rotation we need and how we will feed to get right rotation we want. 3 phase winding for 2 voltages star connection l1 l2 l3 t2t1 yegn 7 rd y l1 t1t2b1b2 8 wh u1 v1.
