We just installed new Baldor 40hp and 60hp Super-E motors today and the windings are a delta configutation.
I can't say I've seen that in a motor in a long time.
The 208 connections were 1-7-6, 2-8-4, 3-9-5.
When the guys energized the 60hp motor it drew over 300 amps and tripped out the drive before it even got to 10hz.
When we megged out the windings it turned out that the 4 and 7 leads were mismarked from the factory.
How does Baldor let that happen?
Aren't all large motors tested before they leave the factory?
