During No load run test we found
1. unbalanced NLA
A=137.8A, B=144.6A, C=147.5A while Supply was A-B=380.3V, B-C=381.6V, C-A=380.9V
2. Motor frame temperature after running was reached to 62C same like DE & NDE bearing housing temperature. Also at lead cables the temperature was up-to 72C.
We rewound the motor in our shop.
Is it normal or there are problems in winding?
