What are the advantages / disadvantages of connecting a 3Phase motor in Delta vs. Wye?
(I have been searching for answers to this question for some time. All forums I've visited gave only half baked answers, so I'm hoping this one will be a little more professional.)
I have a small (0.75HP) 6 wire motor - currently connected as Y with center floating. The name plate states: Y/Δ, 230/380 VAC, which tells me I can configure it both ways. If possible I'd like to get more power out of it, so the question is will a Delta connection achieve this?
Many people have stated that there is no power (or other) advantage or disadvantage between the two connections, but if that is the case, why would so many (larger) motors use Wye-Delta starters? These motors clearly "kick-in" when they switch from Y to Δ. If there is no advantage, then why aren't all motors simple connected in Y, and left that way (Y/Δ starters are much more complex and expensive)?
