AC Motor Supply Wye Delta 1

[7JLAman4]

I have a simple question/inquiry. I'm determining the stator supply configuration for a 6.9kV 3-Phase 12-pole squirrel cage induction motor. What are, if any, the pro and cons to supplying the stator with a WYE connection that does not utilize the neutral vice a Delta connected stator?

Roy - You may have misunderstood. This would be for marine applications. Typically, an ungrounded 3-Ph 3-wire delta system is utilized for distributing power. And "YES" if I were to use a WYE connected stator, the neutral may be left unconnected.
