This 3,000 horsepower, 4,000 volt, 900 RPM AC induction fan motor’s fabricated frame showed signs of fatigue and stress.  The small movements allowed by a worn out frame structure can often lead to early winding failure and Babbitt bearing failure.  Additional structural reinforcement was needed prior to replacing the windings and/or bearings.  The photos show the installation of bracing, webbing, stringers, etc. to make a rigid structure that will adequately support the winding substructure and the Babbitt bearings.  The devil is in the details, and improving the structural components creates a motor that will have a much longer life.
