Abstract

En elektrodynamisk inertivi- brasjons-eksiteringsanordning (l) for eksitering av en del (2) med evne til å opprettholde og forplante tilført vibra- sjonsenergi. Eksiteringsanordningen om- fatter en motorspolemontasje (3, 4) med en spole (3) som er stivt festet til en rørformet spoleformdel (4), en magnet- montasje (5, 6, 7) som er anbrakt kon- sentrisk i forhold til motorspole- montasjen, og en anordning (11) for opp- henging av en magnetmontasje for aksial bevegelse i forhold til motorspole- montasjen, og den er karakterisert ved en bærer (9) som understøtter motor- spolemontasjen (3, 4) og er tilpasset for forbindelse med delen (2) som skal eksiteres.An electro-dynamic inertivation excitation device (1) for excitation of a part (2) with the ability to maintain and propagate applied vibrational energy. The excitation device comprises a motor coil assembly (3, 4) with a coil (3) rigidly attached to a tubular coil mold part (4), a magnetic assembly (5, 6, 7) arranged concentrically relative to the motor coil. - the assembly, and a device (11) for suspending a magnetic assembly for axial movement relative to the motor coil assembly, and it is characterized by a support (9) which supports the motor coil assembly (3, 4) and is adapted for connection with the part (2) to be excited.
