One of the most briskly debated issues in our industry is the comparison – and procedures for – vacuum pressure impregnation (VPI) versus dip & 烤. For this article, the discussion has been expanded to include trickle epoxy and B-stage coils.

Uno de los temas más debatidos en nuestra industria es la comparación y los procedimientos de impregnación a presión al vacío (VPI) versus inmersión y horneado. Para este artículo, la discusión se ha ampliado para incluir bobinas de etapa B y epoxi de goteo.

Relevant standards including IEC 60085 and IEEE 1 have similar definitions for electrical insulating materials (EIM) and electrical insulation systems (EIS). 和任何系统一样, 所使用的材料之间有相互作用, and the insulation system developers take great care to ensure that this interaction does not lead to undesirable outcomes.

Diferentes normas relevantes incluyendo la IEC 60085 y la IEEE 1 definen de forma similar los materiales electro aislantes (EIM) y los sistemas de aislamiento eléctrico (EIS). 你的名字叫什么, existe una interacción entre los materiales usados y los diseñadores de los sistemas de aislamiento cuidan todos los detalles para evitar que esta interacción produzca resultados indeseados.

This webinar recording reviews the failures associated with 3-phase motors on Variable Frequency Drives (VFDs) and how to rewind to limit future failures.

This webinar recording shares some of the “best practice” rewind methods used by (and learned from) EASA service centers around the world: connection recognition, 最好的绝缘材料, 节省时间和精力的电线选择和提示.

High-potential testing is routinely used to assess the ground insulation of AC stator windings in-process, 完成后进行倒带和后送. 本次网络研讨会涵盖了各种类型的高潜力测试, 测试标准, 评估测试结果, 和更多的.

One of the least popular tasks to perform related to winding treatment processes is preparation and cleanup of fits, 螺纹孔和加工表面. M任何 service centers invest additional time in the preparation stage so as to minimize the cleanup stage. The most common approach to protecting these surfaces during winding treatment is to utilize masking compounds or dry release sprays.

在去年, EASA’s technical support staff has received a number of inquiries from members seeking replacement recommendations for Famous Lubricants' “Special Masking Compound” which is currently unavailable. It is believed at this time that the manufacturer intends on continuing production at some point in the future though the time frame is not known. This specific problem leads to a more general question: What is a good practice for choosing a product to mask these surfaces?
