Electric damper actuator LINEA­RIS TE

linear

Ful­ly elec­tro­nic dam­per actua­tor The Linea­ris TE com­bi­nes sta­te-of-the-art and user-fri­end­ly line­ar tech­no­lo­gy with ful­ly elec­tro­ni­cal­ly con­trol­led dri­ve tech­no­lo­gy via con­tact­less Hall sen­sors. A stain­less steel high-helix spind­le with dry­spin® spind­le nut made of high-per­for­man­ce poly­mer ensu­res relia­ble and main­ten­an­ce-free ope­ra­ti­on. Due to the high gra­di­ent, the requi­red engi­ne speed is noti­ce­ab­ly redu­ced in com­pa­ri­son to the clas­sic desi­gn, so that the engi­nes run signi­fi­cant­ly smoo­ther and quie­ter, thus signi­fi­cant­ly increa­sing the ser­vice life of the engi­nes. Ins­tead of the com­mer­ci­al­ly avail­able cas­tings, anodi­sed alu­mi­num machi­ned parts are used with the Linea­ris TE, which are signi­fi­cant­ly more robust with a low weight. The Linea­ris has been deve­lo­ped by prac­ti­tio­ners. Long holes in the bra­ckets allow easy assem­bly. The dry run­ning spind­le nut prevents dirt build-up so that lar­ge and expen­si­ve bel­lows designs are no lon­ger requi­red. Like­wi­se, the regu­lar gre­a­sing is avo­ided by the lub­ri­cant-free con­struc­tion. The BLDC motors used in the dri­ve head are con­trol­led in speed and tor­que and are per­man­ent­ly moni­to­red by inte­gra­ted Hall sen­sors. The dri­ve posi­ti­on is detec­ted and pre­cise­ly con­trol­led by two con­tact­less abso­lu­te encoders. Per­ma­nent red­un­dan­cy tests of the dri­ve sys­tem ensu­re high and ope­ra­tio­nal relia­bi­li­ty.
