Abstract

Ce perfectionnement se rapporte aux marteaux électro-magnétiques comprenant un électro-aimant dont le bobinage est apte à attirer un noyau plongeur déplaçable suivant l'axe du bobinage, avec, pour accumuler l'énergie électrique et la restituer brutalement dans le bobinage, des condensateurs dont la charge et la décharge sont contrôlées par des thyristors reliés à des circuits électroniques fournissant des impulsions de commande. L'invention consiste à prévoir des moyens permettant un réglage du début des impulsions de commande par rapport à la position du noyau dans le bobinage, de manière à pouvoir ajuster le coefficient de << self-induction >> et mettre en résonance les deux systèmes vibratoires, l'un électrique et l'autre magnéto-mécanique, de l'appareil.
