Connection of rotor bars to end rings through approximately 10,000 HP is via induction brazing. Screens will be stainless steel. Fan systems will be non-sparking. Minimum stator core plate material will be C5. 2.4.9.5 Lower than conventional noise levels.
Motors are available for hazardous locations.
Shaft forgings are ultrasonically inspected. Damped unbalance response analysis. Three plane balancing of the rotor. Testing with contract coupling and idling adapter or mass moment simulator. A single VPI treatment of the stator will meet the requirements of this paragraph.
