Rated torque family pre-screen

Pre-screen ZHR-H and ZHR-P families before engineering review.

This tool compares only the reviewed ZHR-H and ZHR-P published rated-torque ranges. It does not select an exact model or evaluate speed, stroke, protocol, envelope, duty cycle, or thermal suitability.

2. Torque typeRated or peak
3. ContextApplication for engineering review

What rated/continuous output torque must the joint support?

Below 1.6 Nm or Not Yet Known

The reviewed ZHR-H/ZHR-P family facts do not support an automatic shortlist without a confirmed rated torque requirement.

1.6 Nm to Below 5 Nm Rated

This requirement is within the published ZHR-P range, but it cannot exclude a higher-rated ZHR-H model. Compare both families and verify the exact model.

5 Nm to 40 Nm Rated

Both published family ranges include this band. Compare exact models, speed, duty cycle, interface, envelope, and thermal limits.

Above 40 Nm to 91 Nm Rated

Within the reviewed ZHR-H/ZHR-P facts, only the ZHR-H published rated family range includes this band. Model verification is still required.

Above 91 Nm Rated

This exceeds the reviewed ZHR-H/ZHR-P rated family ranges. Engineering review is required before discussing alternatives.

2. Is that torque value rated/continuous or peak?

Rated / Continuous Torque

Continue with a family-range shortlist. Exact model selection still requires speed, duty cycle, voltage, envelope, and cooling.

Peak / Short-Duration Torque

Peak torque cannot be used as a continuous rating. Provide peak duration, repetition, speed, duty cycle, and thermal conditions.

Not Sure

Engineering review is required to separate continuous demand from transient peak demand before comparing families.

3. What is the primary operating scenario?

Humanoid / Rigid Arm

Smooth, continuous, precise trajectories.

Quadruped / Legged

Dynamic impact absorption, high back-drivability.

Research / Hobby

Prototyping, high cost-performance ratio needed.

AGV / Mobile Base

Continuous driving, load bearing capabilities.

Preliminary Shortlist

This screening result is not a final selection. Confirm the exact model and operating point through engineering verification.
