Robot Joint Backdrive Torque Measurement Passport
Select breakaway, running, directional or state-specific backdrive torque. Fix the application/measurement plane, powered and brake state, motion, temperature, fixture losses and calculation before comparing results.
Method record
| Field | Required declaration | Project entry / evidence |
|---|---|---|
| Measurand | Breakaway / running / directional / state-specific; peak, mean, median, percentile or fitted value | |
| DUT and planes | Included motor, reducer, brake, drive, encoder, bearings, fixture; torque, position and speed planes; sign and ratio | |
| Electrical and brake state | Powered/unpowered, bus, enable, mode, command/current, compensation, brake command and release evidence | |
| Motion and load | Direction, speed or torque ramp, acceleration, travel, cycles, dwell, reversal, orientation and external/gravity load | |
| Thermal and mechanical state | Temperatures, warm-up, cooling, lubricant, fixture, alignment, cable routing and assembly revision | |
| Acquisition and calculation | Sensor IDs, ranges, zero, calibration/verification, timing, filtering, onset/window rule and statistic | |
| Validity and acceptance | Invalid-run, repeat, retest, uncertainty decision rule, tolerance source and evidence link |
Scope limit: No universal Weiheng backdrive value, range, accuracy, sampling rate or acceptance limit is asserted. Backdrive torque is not the same as no-load running friction.
