Title (EN) FREQUENCY MODULATION FOR MAGNETIC PRESSURE PULSE TOOL
(FR) MODULATION DE FRÉQUENCE D'UN OUTIL À IMPULSION DE PRESSION MAGNÉTIQUE
Abstract:
(EN) An apparatus for applying a magnetic pressure to a work piece includes an inductor configured to be disposed in proximity to the work piece and a controller electrically connected to the inductor and configured to control a supply of electrical power in order to output a first voltage over a selected frequency range to determine a frequency that provides a maximum current or a frequency that provides a current within a selected range of the maximum current to the inductor.
(FR) La présente invention concerne un appareil servant à appliquer une pression magnétique sur une pièce, comprenant un inducteur conçu de manière à être disposé à proximité de la pièce et un dispositif de commande connecté électriquement à l'inducteur et conçu de manière à commander une alimentation en énergie électrique afin de délivrer une première tension sur une plage de fréquences choisie de manière à déterminer une fréquence qui fournit un courant maximum ou une fréquence qui fournit un courant dans une plage choisie du courant maximum à l'inducteur.
