About this file
These are technical engineering drawings and material specifications for a three-phase synchronous generator manufactured by Yaskawa Electric (MFG CO., LTD). The documents consist of sectional drawings with component numbering and a detailed material list specification table.
The material list identifies 28 components spanning mechanical and electrical assemblies, including the shaft, lower guide bearing, sole plate, flywheel, brake, cooling fan, frame, stator core, pole, spider, armature windings, field windings, upper bracket, thrust bearing, thrust runner, and thrust beam. Each component specifies the material type (such as rolled steel plate, white metal, steel forging, copper bars, and silicon steel strip) with corresponding material specifications and standards, primarily referencing ASTM standards and Japanese Industrial Standards. The drawings indicate component locations and relationships within the generator assembly, with dimensional references and section views. Notable specifications include materials such as ASTM A293 GR.B, ASTM A285, ASTM A866 CL.E, and various copper and brass designations. The document notes that certain items are not supplied by Yaskawa and references Japanese Industrial Standards with NEMA equivalents for electrical properties. This appears to be part of Amendment 0005, Section J, Attachment 6 of a federal contract solicitation.
