El propósito de este artículo es proporcionar suficientes fundamentos de rodamientos para que aquellos que son responsables de la aplicación, operación, mantenimiento y reparación de motores eléctricos puedan tomar las medidas necesarias para minimizar las fallas prematuras de los rodamientos y mejorar la posibilidad de que los rodamientos duren hasta el " "final de la vida útil", que normalmente se denomina vida útil del rodamiento L10.

The purpose of this article is to provide enough rolling element bearing fundamentals so those who are responsible for the application, operation, maintenance and repair of electric motors can take the necessary steps to minimize premature bearing failures and enhance the possibility of bearings lasting until the "end of life" predictions, which is normally referred to as L10 bearing life.

The most basic tool a vibration analyst uses is the vibration spectrum. The spectrum is a graphic illustration of the frequencies present in a vibration signal and their relative amplitudes. This article provides a basic overview, examines settings and provides tips.

La herramienta más básica que utiliza un analista de vibraciones es el espectro de vibraciones. El espectro es una ilustración gráfica de las frecuencias presentes en una señal de vibración y sus amplitudes relativas. Este artículo proporciona una descripción general básica, examina la configuración y ofrece sugerencias.

Determining the source of noise in a motor is often much more challenging than correcting it. However, a methodical approach to investigating the noise can narrow down the possible causes.

This PowerPoint presentation is available for members to use to present the factors that should be considered when customers are faced with making the difficult decision to repair their existing motor or purchase a replacement.

Determining the source of noise in an electric motor is often more challenging than correcting it. A methodical investigative approach, however, can narrow the possibilities and make it easier to resolve the issue—with one caveat. If the noise is due to something in the motor design (e.g., a manufacturing defect or anomaly), a solution may be impossible or impractical.

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

To ensure the reliability of an RV’s electrical devices, especially electric motors, campers must know the service voltage of the hookup their RV is using. Teaching consumers to check that before they plug in the vehicle could save them many headaches.

Centrifugal pump failures are most commonly attributed to seal failure, impeller damage and bearing failures. A good understanding of failure modes for seals, impellers and bearings is essential to providing customers with reliable pump repairs.
