Application Decision Summary

A buyer should use this page to decide which joint risks belong to actuator selection, which belong to system validation, and what sample evidence is needed before pilot purchase.

Best Evidence

Start with payload-to-joint mass fit and connect it to the real robot duty cycle instead of reviewing catalog values alone.

Primary Risk

A joint is selected without considering mobile power limits

Next Buyer Action

Prepare axis count, payload, reach, and speed target plus validation targets before requesting samples or commercial terms.

Application Fit Method

Application pages should help a buyer decide whether the actuator direction fits the robot job before a commercial conversation starts.

Payload-to-joint mass fit

3–10 kg payload range, joint mass 0.4–1.5 kg

Mobile robots have tight payload, battery, and stability budgets.

Bus/interface fit

CAN 1 Mbps or EtherCAT 100 Mbps, 1–4 ms cycle time

Integration time depends heavily on controller and communication compatibility.

Thermal duty

20–40% of peak torque RMS over pick-place-return cycle

Repeated manipulation can heat compact joints even when peak torque is moderate.

Robot-Level Validation Plan

The actuator should be checked against the robot motion cycle, not only against a bench specification.

Signal to Check	Review Basis	Evidence to Ask For
Payload-to-joint mass fit	3–10 kg payload range, joint mass 0.4–1.5 kg	Share battery voltage, driver current, and duty cycle before selecting winding and ratio.
Bus/interface fit	CAN 1 Mbps or EtherCAT 100 Mbps, 1–4 ms cycle time	Confirm connector, cable routing, encoder, and communication requirements during RFQ.
Thermal duty	20–40% of peak torque RMS over pick-place-return cycle	Share battery voltage, driver current, and duty cycle before selecting winding and ratio.

Acceptance Thresholds to Define

Define measurable pass/fail thresholds before the sample arrives. This prevents a subjective review where one team checks torque, another checks packaging, and nobody records whether the actuator can move toward pilot build.

Payload-to-joint mass fit: Mobile robots have tight payload, battery, and stability budgets.
Bus/interface fit: Integration time depends heavily on controller and communication compatibility.
Thermal duty: Repeated manipulation can heat compact joints even when peak torque is moderate.

When This Application Needs Extra Review

Some application risks are system-level and cannot be solved by an actuator choice alone. Identify those risks before sample purchase.

A joint is selected without considering mobile power limits: Share battery voltage, driver current, and duty cycle before selecting winding and ratio.
Manipulator integration is delayed by connector or bus mismatch: Confirm connector, cable routing, encoder, and communication requirements during RFQ.

Application Data to Send First

A useful application inquiry includes enough robot context for engineering to evaluate torque, packaging, control, and delivery risk together.

Fixed Constraints

Axis count, payload, reach, and speed target
Voltage/current limits and controller/bus preference
Brake, encoder, shaft/flange, and connector needs

Review Targets

Mobile platform thermal environment and duty cycle
Prototype quantity and target production volume

Application Evaluation Matrix

Evaluation Metric	Typical Range	Buyer Relevance

Buyer FAQ

Can QDD actuators be supplied with interface changes?

OEM programs can review encoder, connector, cable, and bus-interface requirements before sample build.

Can you support both prototype and batch needs?

Yes. Share the sample quantity, validation plan, and expected production forecast so the path is realistic.
