Abstract
Método de producción de una escobilla para una máquina dinamoeléctrica, que incluye los pasos consistentes en compactar un polvo del que ha de fabricarse la escobilla alrededor de un extremo de un conductor eléctrico con el resto del conductor sobresaliendo del polvo compactado, y calentar después en una atmósfera no reductora el conjunto del conductor y el polvo compactado para sinterizar el polvo bajo la forma de la escobilla requerida y conectar el conductor a la escobilla tanto física como eléctricamente.
