The new breed of DC ser­vo­mo­tors

DEMM Engineering & Manufacturing - - MOTORS & DRIVES -

DC ser­vo­mo­tors t hat are robot­i­cally man­u­fac­tured to a cus­tomer’s online cus­tomi­sa­tions.

Shown here is the latest style DC ser­vo­mo­tor that has been au­to­mat­i­cally man­u­fac­tured from a cus­tomer’s di­rect in­puts into an in­ter­net based mo­tor con­fig­u­ra­tion tool. The first fea­ture to ob­serve on the mo­tor, gear­head and en­coder com­bi­na­tion is the com­plete lack of any screws, pins or clamps be­tween any of the com­po­nents. This is achieved even for the en­coder with con­tin­u­ous f low laser weld­ing. By re­mov­ing the tra­di­tional mount­ing plate de­sign be­tween the DC mo­tor and the plan­e­tary gear­head it saves on over­all length. A com­plete weld revo­lu­tion be­tween the mo­tor and gear­head also elim­i­nates the pos­si­bil­ity of oil or wa­ter ingress into the mo­tor at this point. The en­coder ca­ble exit is also sealed pro­vid­ing both strain re­lief and seal­ing. All maxon DC ser­vo­mo­tors do not re­quire in­ter­nal air­flow or brush cool­ing al­low­ing them to be com­pletely en­closed. Us­ing the web con­fig­u­ra­tion tool fea­tures on the mo­tor in­clud­ing the shaft length, shaft f lats, ca­ble lengths, gear ra­tios and wind­ing char­ac­ter­is­tics can all be cus­tomised to best suit the ap­pli­ca­tion.

Nor­mally a ro­bust, ef­fi­cient and cus­tomised mo­tor drive that is man­u­fac­tured to or­der in Switzer­land would take a min­i­mum of four weeks to pro­duce. This new style of man­u­fac­tur­ing rep­re­sents some­what of a break­through with the prod­uct be­ing shipped in un­der 11 work­ing days.­quiry #150820.
