Abstract

Die Vorrichtung (1) zum Magnetisieren eines Magnetsystems beinhaltet vorzugsweise mehrere Pulsgeneratorschaltungen (2.1-2.4), welche derart gegenseitig angeordnet sind, dass sich ihre Magnetfelder verstärkend überlagern. Jede Pulsgeneratorschaltung (2.1-2.4) weist ein Kondensatorelement (21), eine mit dem Kondensatorelement (21) elektrisch verbundene Magnetisierspule (22) und ein Schaltelement (23), durch dessen Betätigung die Magnetisierspule (22) mit einem durch Entladung des Kondensatorelements (21) entstehenden Strompuls mit begrenzter Pulsdauer beaufschlagbar und somit der Aufbau eines Magnetfeldes auslösbar ist. Die Pulsgeneratorschaltung (2.1-2.4) ist derart aufgebaut, dass die Pulsdauer des Strompulses auf einen Wert zwischen 10 µs und 500 µs begrenzt ist. Dank solch kurzen Pulsdauern ist die unerwünschte Erwärmung der Magnetisierspule (22) klein, so dass die Vorrichtung (1) in automatisierten Produktionsanlagen mit Taktraten unter 1 s eingesetzt werden kann.
