Compact custom servo motors, micro drives, smart servos, and actuator assemblies for grippers, end effectors, and dexterous hand mechanisms.
| Evaluation Metric | Typical Range | Buyer Relevance |
|---|---|---|
| Servo size class | Micro to compact smart servo | The gripper envelope often limits motor diameter, board area, and connector choice. |
| Grip duty cycle | Short pick cycles, hold torque, stall-heavy grip, or compliant grasp | Small servos overheat quickly when holding force, so current limit and thermal derating must be defined. |
| Cable flex life | Static routing, moving finger loop, wrist rotation, or tool-change harness | End effector failures often come from cable strain, connector fatigue, and routing after the mechanism is frozen. |
| Situation | Recommended Path | Evidence to Confirm |
|---|---|---|
| The gripper holds force for long periods | Select the servo around continuous hold current, stall time, thermal derating, and gear load instead of peak force only | Grip force, hold duration, current limit, heat-rise target, gear material, and load-cycle count |
| Force or compliance control is expected | Clarify whether control comes from current mode, external force sensing, firmware limits, or mechanism compliance | Control mode, sensor input, firmware responsibility, calibration target, and pass/fail grip test |
| The finger package leaves little space for cables and boards | Review micro motor, micro drive, flex cable, connector, and service loop together before mechanism freeze | Finger CAD, cable path, connector size, moving-loop bend radius, PCB outline, and assembly sequence |
| Checkpoint | Method | Pass Evidence |
|---|---|---|
| Grip duty validation | Measure force, current, stall time, temperature rise, travel repeatability, and gear condition across repeated cycles | Cycle-test record with current limit, force result, and thermal margin |
| Cable and connector durability | Check moving-loop bend radius, strain relief, connector retention, and failure points after repeated finger motion | Cable routing approval, connector retention notes, and post-cycle inspection |
| Force-control acceptance | Verify current-mode behavior, sensor input, calibration, limit handling, and application-side control assumptions | Acceptance test data showing grip behavior, limit response, and firmware version |
Application Evidence
For application pages, the first engineering review connects robot duty, control stack, and validation risk before architecture lock.
Motor, drive, actuator, firmware, harness, fixture, and test responsibility are separated before quotation.
Open items such as torque-speed data, duty cycle, envelope, protocol, encoder, and target launch country are flagged early.
Prototype checks are tied to load profile, thermal rise, backlash, noise, current limit, and end-of-line pass criteria.
Tooling, fixture, pilot lot, annual forecast, packaging, documentation, and delivery assumptions are made explicit.
| Evidence Group | What to Attach | Buyer Value |
|---|---|---|
| Motion and thermal | Torque-speed target, current limit, duty cycle, temperature path, and derating assumption. | Separates continuous-duty capability from peak torque claims before sample approval. |
| Interface control | STEP or drawing revision, flange, bore, cable exit, connector, encoder, and protocol map. | Keeps motor, drive, harness, and firmware assumptions aligned before tooling. |
| Validation record | EVT, DVT, PVT gate criteria, EOL checklist, burn-in profile, and serial or lot traceability. | Gives engineering and procurement a common pass/fail basis for pilot lots. |
| Commercial path | Prototype quantity, pilot build target, annual forecast, delivery country, and packing notes. | Improves quote precision and avoids late shipping or documentation surprises. |
Yes. Send the envelope, force target, motion travel, feedback need, and cable route.
Yes. Current-mode behavior, torque limiting, calibration, and sensor interface options can be reviewed when acceptance tests are defined.
