Small DC servo mo­tors ex­tended en­coder range

DEMM Engineering & Manufacturing - - MOTORS & DRIVES -

The Maxon DCX mo­tors are grow­ing in­creas­ingly pop­u­lar be­cause of the ground-break­ing on­line con­fig­u­ra­tion and au­to­mated pro­duc­tion fa­cil­ity.

It al­lows a cus­tomer to di­rectly mod­ify the fea­tures of the mo­tor and se­lect var­i­ous gear­head and en­coder op­tions. The selectable range of en­coders has just in­creased with the new three-chan­nel range of op­ti­cal 2RMF and SCH sen­sors.

Once the en­coder is se­lected the res­o­lu­tion op­tion is given with selectable counts per turn from 3,000 to 5,000. The en­coders fea­ture a wide in­put volt­age range from 4.5 to 30V DC. The out­put sig­nal is EIA stan­dard RS422 us­ing an 26C31 driver.

With the con­fig­u­ra­tion tool you can se­lect a low back­lash gear­head or Maxon can sup­ply zero back­lash high re­duc­tion gear­heads that when used in con­junc­tion with the 5,000cpt will give you a 20,000 quad count po­si­tion ca­pa­bil­ity. Mul­ti­ply this by the gear­head ra­tio se­lec­tion and the re­sult is an ex­tremely ac­cu­rate po­si­tion­ing drive.
