JOINTDEX

What goes into one joint.

Pick a motor, a reducer and an encoder and the stored specs are compared one by one to say whether they combine. For now you can see what sits in each slot.

Slot selection is being prepared.

MOTORB · Motors276 candidates · 369 evidence
REDUCERC · Reducers55 candidates · 65 evidence
ENCODERD · Encoders119 candidates · 214 evidence

Candidate counts are the products placed in that family and their evidence records.

  • The verdict opens once the weighting is signed off

To settle before a verdict

Three things a verdict needs.

Joint compatibility opens when all three are in place.

01

Candidates in all three slots

Each slot needs at least one product named in an official document.

Candidates present — B 276 · C 55 · D 119
02

Comparison parameters in hand

Rated torque · backlash · torsional stiffness · output shaft spec · encoder interface.

Being collected — filled in by the monthly re-survey
03

Weighting signed off

The verdict opens once an engineering authority settles which axes count and by how much.

Awaiting sign-off

Candidates by family.
