I been having trouble with this motor 460v 3phase and I megged it and got 1.8 G on each of the 3 leads. It starts up and runs for ten minutes stops by water pressure switch. When it trys to restart the starter pulled in but it seemed as if it did not get the full 460 to the motor. The motor turned very very slowly and tripped out at that time. I took a volt reading at both sides of starter and it appears to read 430v only at time of slow running . When it is running the amp reading is below full load and appears it is fine, but won't start back up until 10-15 minutes later. No control power or switch problem that I can see. Megged motor 3x. 20hp. When running fine 460 at starter.
Checked all connections in motor and starter and disconnect. Any ideas ????
