There are many factors to consider when re-stacking a stator. Those include the materials, core compression, length of the core, vents, spacers, vent construction and more. This article focuses on taking proper measurements when re-stacking a stator core and how to go about stacking the stator to ensure those dimensions are met.

Hay muchos factores que se deben considerar al re apilar el núcleo del estator. Estos incluyen los materiales, la compresión y largo del núcleo, los orificios de ventilación, los espaciadores, la construcción de los orificios de ventilación y más. Este artículo se centra en tomar las medidas adecuadas para volver a apilar el núcleo de un estator y cómo garantizar que se cumpla con esas dimensiones.

There are plenty of generic mobile device policies floating around the web. Sadly, many of them focus heavily and narrowly on the disadvantages of team members having personal devices at their workstations. Too often organizations take the path of excluding mobile devices from the work area because it’s easy rather than reaping the benefits they offer.

Existen muchas políticas genéricas sobre el uso de los dispositivos móviles flotando en internet. Dependiendo del entorno particular y de las herramientas utilizadas, es razonable y responsable evaluar los riesgos potenciales para la seguridad y la protección. Sin embargo, con mucha frecuencia, las organizaciones toman el camino de excluir los dispositivos móviles del área de trabajo porque es una medida fácil, en lugar de aprovechar los beneficios que ofrecen.

Accuracy and precision of measuring & test equipment (M&TE) have been topics of previous Currents articles (November and December 2014). A related topic that was not covered in the previous articles is resolution. The Joint Committee for Guides in Metrology document JCGM 200:2012 defines resolution as “the smallest change in a quantity being measured that causes a perceptible change in the corresponding indication.” Simplified, it’s the smallest difference that can be measured by the subject equipment. The accuracy of the M&TE must be greater than (less accurate) or equal to the resolution. That is, the M&TE must be able to indicate the value that is compared to the standard during calibration.

Let's briefly revisit the importance of accuracy and precision.

La precisión y exactitud de los equipos de prueba & medida (M&TE) han sido tratadas en artículos previos de Currents (noviembre y diciembre de 2014). Un tema relacionado que no fue cubierto en dichos artículos es la resolución. Este artículo cubrirá ese tema.

Inspection and testing are two of the most important activities performed by service centers. The service center should be focused on minimizing measurement error such that the measurement values are as close to actual values as needed to properly evaluate the measured item.
