When a core loss test reveals localized hot spots, or visual inspection identifies physical damage, the ability to repair the damage in a cost-effective manner means the difference between repair or replacement.
Unless great care is taken, pulling magnet wire from a motor stator often bends or splays the lamination’s end teeth. Bent teeth, or teeth that have been splayed outward at the ends of the core stack, will likely compromise the quality of the repair job. Therefore, we have designed and implemented the use of disc clamps to hold the stator tooth tips in place while pulling magnet wire from the slots. The clamping fixtures described in the photos have helped ensure that we avoid damaging the stator teeth during the stripping process.
A no ser que se tenga mucho cuidado, tirar del alambre magneto al desmantelar el estator de un motor a menudo deforma o dobla los dientes de las laminaciones. Estos dientes deformados comprometerán la calidad de la reparación y hay estudios que demuestran que este problema puede reducir la eficiencia del motor. Sin embargo, aunque esta reducción puede ser pequeña, genera altos costos y desperdicio de energía.
Induction motor stator cores can be manufactured using single-piece laminations, however, for larger stators, or when minimizing scrap material, the stator laminations are segmented. While most service center repairs of machines with segmented stator laminations require no special attention, this article reviews a few scenarios that are important to be mindful of.
Los núcleos de los motores de inducción se pueden fabricar con laminaciones de una sola pieza, sin embargo, para estatores muy grandes o cuando se minimiza el material de desecho, las laminaciones del estator son segmentadas. Aunque la mayoría de las reparaciones en el centro de servicio de las máquinas con estatores con laminaciones segmentadas no requieren atención especial, este artículo analiza algunos escenarios que es importante tener en cuenta.
Most rotor, stator and armature laminations used in industrial electric motors and generators are made from non-oriented, cold-rolled electrical steels. However, there is a lot of variation in the specific properties in these electrical steels. This article will discuss properties of electrical steels, as well as the methods used to optimize the magnetic characteristics of the laminations, specifically through the annealing process.
This 40-page booklet provides great advice for obtaining the longest, most efficient and cost-effective operation from general and definite purpose electric motors.
