Periodically, members will need to update computer systems with EASA's AC Motor Verification & Redesign (ACR) software program installed. The procedure for moving the program to a new computer depends on the version of the currently installed program.

Periódicamente, los miembros deberán actualizar los sistemas informáticos con el programa de software ACR instalado. El procedimiento para mover el programa a una nueva computadora depende de la versión instalada actualmente.

This article addresses methods for removal and installation of couplings on straight or tapered shafts. The most common good practice methods are described.

The goal of vacuum pressure impregnation is complete saturation of a winding with insulating resin. As resin penetrates the insulating materials, it causes them to darken. If some insulation is a lighter shade, the coil or jumper is not fully saturated. The winding is not properly protected, and if the problem is not addressed, it is likely to cause premature failure of the unit. This could result in costly warranty work, or at a minimum, will be a failure to provide your customers with the quality they expect and deserve.

Este artículo abordará los métodos para demontar e instalar acoplamientos en ejes rectos o cónicos. En él se describirán los métodos que usan buenas prácticas más comunes.

El objetivo de la impregnación por vacío y presión (VPI) es saturar completamente un devanado con resina aislante. A medida que la resina penetra en los materiales aislantes, los oscurece y al drenar la resina VPI del devanado, todo el aislamiento de las cabezas queda oscuro en un tono uniforme. El aislamiento de la conexión también debe quedar oscuro de forma pareja. Si algún aislamiento muestra un tono más claro, la bobina o el puente no han quedado completamente saturados y el devanado no está debidamente protegido. Si no se soluciona el problema, es probable que esto provoque un fallo prematuro en el equipo. Esto podría generar una garantía costosa o, como mínimo, la reparación no brindará a sus clientes la calidad que esperan y merecen.

When possible, it is good practice to perform an uncoupled, no-load run on an induction motor as an incoming diagnostic test. A no-load run should also be performed after assembly, and ANSI/EASA AR100-2020 states that “no-load running tests should be made at rated voltage and rated frequency.” In this article, we’ll discuss some of the reasons why this is important and some things to consider when you cannot meet both requirements.

Sales and marketing departments often work alongside each other instead of performing as a team. If marketers and salespeople don't pull together, your company will never exploit its full potential. Many B2B industrial companies suffer from an old problem; there is hardly any acceptance, appreciation and support for their own marketing department. There is a lack of understanding of why marketing is firstly so important and secondly a complex and time-consuming area. Marketing is unfortunately rarely perceived as a specialist department.
