U1 v1 w1 colours. For star delta staterthe motor connection must have 6 cables from control panel and 6 terminals at induction motor u1u2v1v2w1w3to wiring the motor connection for star delta starterthe important thing that we must fully understand is about the basic of star delta magic triangle. 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. 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.

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.

On a star delta system is there ever a time when a single phase might go between a single winding eg. 3 phase winding for 2 voltages star connection l1 l2 l3 t2t1 yegn 7 rd y l1 t1t2b1b2 8 wh u1 v1. 3 phase winding for 2 voltages delta connection l1 l2 l3 t1t2 yegn 7 rd y l1 t1t2b1b2 8 wh u1 w1 u2 v1 3 motor w2 v2 tc l2 l3 5 or 3 gy 4 bu 2 bk 6 vi 1 bn m45 fig.

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. U1 w1 u2 v1 3 motor w2 v2 tc l2 l3 5 or 3 gy 4 bu 2 bk 6 vi 1 bn m44 fig. More electrical engineering interview questions. Rotation u can mark r to u1 y to v1 and b to w1. How to change rotation of motor in clockwise direction no present motor connection.
Is this answer correct. From this triangle diagramwe can determine the correct phasecable termination for right terminal and the rotationas we knowthe star.
