Brush Stagger to Optimize Brush Life Through Current Density

  • January 2025
  • Number of views: 1620
Article

When working with DC machines, it’s not uncommon to find a customer who runs different products requiring a range of armature current. Unlike other conductors, where lower current is a good thing, carbon brushes are designed for a narrow range of current density. A unique aspect of carbon brush life is that brushes operating at a much lower current density than they are designed for do not last nearly as long as expected.

  • Number of views: 584
Article

Durante los 90, las normas gubernamentales para la eficiencia de los motores eléctricos fabricados generaron preocupaciones de que pudieran surgir regulaciones o normas para la reparación de motores eléctricos. Como representante de la industria de reparación de motores eléctricos, EASA respondió buscando el reconocimiento de su Práctica Recomendada para la Reparación como Norma Nacional Americana. Ser proactivo en la obtención de dicho reconocimiento significaría que, en nombre de la industria de la reparación, EASA crearía la norma de las mejores prácticas de reparación para la industria.

Submersible Pump Stator Oil Guidelines

  • November 2024
  • Number of views: 1533
Article

In addition to seal oil, some submersibles have an oil filled stator cavity. The oil in the stator cavity very efficiently transfers heat from the stator winding and core, and especially from the rotor, to the pump casing where convection carries it to the pumpage in which the pump is submerged. While the specifications for seal oil are fairly flexible, stator cavity oil has more constraints.

Pautas Para el Aceite del Estator de las Bombas Sumergibles

  • November 2024
  • Number of views: 1020
Article

Además del aceite de sellado, algunas bombas sumergibles tienen una cavidad del estator llena de aceite. Este aceite transfiere de manera muy eficiente el calor desde el devanado y el núcleo del estator, y especialmente desde el rotor, hasta la carcasa de la bomba, donde la convección lo lleva al líquido de bombeo en el que está sumergida. Si bien las especificaciones para el aceite de sellado son bastante flexibles, el aceite de la cavidad del estator tiene más restricciones.
