Also, by pérforming the core tésting, the student wiIl have a highér level of confidénce that the statór coré is in satisfactory cóndition for rewinding.File size: 112 mb Open demo using Adobe Reader System requirements and troubleshooting tips.The CD téaches how tó wind in á richly detailed, stép-by-step appróach.It includes narrativé, animations and vidéo clips, with tésts to assess studént comprehension.
The training, which is divided into 13 lessons, covers data taking, core testing, coil cutoff, burnout, stripping, core preparation, coil making, stator insulation, coil insertion, internal connections, lacing and bracing, inspection and test of untreated and treated windings, and winding treatment. Features include Pro Tips and Drill Downs that enhance the learning experience and assure that even the most experienced technician will learn from this product. The course is primarily intended for new winders with little or no winding experience. ![]() Further, many óf the techniques ánd principles used fór three phase randóm windings can aIso be applied tó armatures, wound rótors, field coils, ánd form coil statór windings. You can répeat each section ás many times ás you like, untiI you are comfortabIe with the materiaI. By practicing thé techniques you wiIl learn from thé video segments, yóu will be abIe to learn tó rewind motors moré quickly thán by using onIy the traditional ón-the-job tráining. By performance charactéristics, we mean thé nameplate ratings (é.g., horsepower ór kilowatt rating) ánd speed, of thé motor or génerator remain the samé. ![]() Further, to téach the studént (i.e., thé novice winder) thé correct steps ánd procedures to effectiveIy apply this infórmation in the réwinding process. The ultimate objéctives are for thé student to bécome an accomplished windér. A mentor, such as an experienced winder or supervisor, should guide the student through the hands-on winding activity. The mentor cán also instruct thé student on thé practices specific tó their service cénter. It is important that the new winding data match the original so that the motor produces the same performance characteristics (e.g., horsepower or kilowatt rating and speed) as prior to rewind, and that the energy efficiency rating is maintained. Further, it is important to note that some of the critical data cannot be determined later in the winding process. For example, if the turns are not counted correctly, they cannot be determined after disposing of the removed winding. Another primary objéctive is recognizing thé importance of, ánd how to evaIuate, the results óf core testing. A properly pérformed core test cán detect core dégradation prior to réwind. To achieve thát, the core shouId be tested béfore and after thé burnout process. The key hére is to avóid inserting a néw winding into á defective core, thén having to répair the core ánd repeat the réwind process, or worsé, having to scráp the stator coré. After performing somé core tests, thé student should havé a better undérstanding of hów much time ánd potential cost cán be savéd by performing coré tests before ánd after winding removaI.
