Determining Noise Sources in Electric Motors

  • May 2020
  • Number of views: 514
  • Article rating: 4.8
Article

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 and therefore make it easier to resolve the noise issue. There is a caveat. If the cause of the noise is due to something in the motor design, that is, a manufacturing defect or anomaly, a solution may not be possible or practical.

A menudo, determinar la fuente del ruido en un motor eléctrico es más un desafío que corregirla. Sin embargo, un enfoque metódico puede reducir las causas posibles y por consiguiente facilitar la resolución del problema. Una advertencia aquí es que, si el ruido está relacionado con el diseño del motor, es decir, por un defecto de fabricación, puede que no sea posible o que no sea práctico obtener una solución.

Root Cause Failure Analysis, 2nd Edition

  • September 2019
  • Number of views: 2905
  • Article rating: 5.0
Book

This book was developed to help electric motor technicians and engineers prevent repeated failures because the root cause of failure was never determined. By using a proven methodology combined with extensive lists of known causes of failures, one can identify the actual cause of failure without being an “industry expert.” In fact, when properly used, this material will polish one’s diagnostic skills that would qualify one as an industry expert.

Dealing with wet/flooded motors

Recovering from disaster: Saltwater becomes a major problem

  • August 2019
  • Number of views: 714
  • Article rating: No rating
Article

Flooding in the aftermath of tropical storms (hurricanes, monsoons and cyclones) with heavy rainfall will often shut down hundreds of plants along the Gulf Coast from Florida to Texas and other places around the world. To get them up and running again, maintenance departments and motor repairers face the daunting task of cleaning muck and moisture from many thousands of electric motors and generators. The process in such situations can take weeks, if not months, and requires special clean-up procedures for motors contaminated by saltwater.

Article

A menudo, las inundaciones producidas por las intensas lluvias de las tormentas tropicales (huracanes, monzones y ciclones) colapsan cientos de plantas industriales a todo lo largo de la costa del golfo de México, desde la Florida hasta Texas y en otros lugares del mundo. Para retomar las actividades productivas, los departamentos de mantenimiento y los reparadores enfrentan la difícil tarea de limpiar la suciedad y desalojar la humedad en miles de motores y generadores eléctricos. El proceso en tales situaciones puede tomar semanas o meses y requiere procedimientos especiales para limpiar los motores contaminados con agua salada.
