Integrated harmonic actuator module
304 Nm peak harmonic robot actuator, 100:1 ratio: MGA-HJ-80-100
This is the harmonic-drive record in the set. Model 1 lists a 100:1 ratio, 108 Nm rated torque, 304 Nm under the source’s “Peak torque (>3 s)” label, 62 rpm peak speed, and 1,600 g mass. The catalogue mentions through-bore, brake, and torque-sensor customization; request the exact option stack and resulting drawing before selection.

Selection questions that still need an application answer
A catalogue value narrows the comparison. It does not establish fit for a mechanism without the load profile, mounting stack, controller, and operating environment.
- Required continuous torque, peak torque, peak duration, and repetition rate
- Output speed, acceleration, reversal, impact, and duty cycle
- Mounting face, bolt pattern, shaft/bore, cable route, and external loads
- Supply voltage, control mode, communication, feedback, brake, and protection requirements

Have a torque-speed profile or mounting drawing?
Send it with the duty cycle and controller requirements for a model-specific engineering review.
02 · Check interfaces
Resolve the mechanical and electrical stack
Compare the original drawing with the mating parts, loads, cable route, connectors, supply, communication protocol, and feedback requirements.
03 · Confirm the build
Request configuration-specific evidence
Confirm the selected Model 1/Model 2 configuration, current drawing revision, option content, test conditions, and validation evidence before freezing a design.
Original drawing and motor performance map
The drawing is reproduced from the supplied source image unchanged, including any visible source mark. The performance-map image is also used unchanged. Its graphic identifies torque, speed, power, current, and efficiency axes, but does not identify curve names or a Model 1/Model 2 configuration.

MGA-HJ-80-100 frequently asked questions
Are the harmonic actuator customization options one standard package?
No option stack is defined in the catalogue. It mentions through-bore, brake, and torque-sensor customization; request a configuration-specific drawing and the resulting rated limits for the combination under review.
What torque and speed does MGA-HJ-80-100 list?
Model 1 lists 108 Nm rated torque and 304 Nm under the source label “Peak torque (>3 s),” with 46 RPM rated speed and 62 RPM peak speed. The catalogue operating-condition note below applies unless a field is specified otherwise.
What do Model 1 and Model 2 mean?
The source page populates Model 1 only. The Model 2 column is marked “Not specified in source”; this page does not infer a second configuration.
Are the listed values a complete duty-cycle guarantee?
No. Use the table as a source-backed screening record. Confirm the required torque-speed profile, peak duration and repetition, duty cycle, thermal limits, mounting loads, controls, and operating environment before design release.
Which motor-performance-map curves apply to each configuration?
The supplied map shows axes for torque, speed, power, current, and efficiency but does not label the curves or identify a Model 1/Model 2 configuration. Confirm the applicable configuration and test conditions before using the map for controller or thermal sizing.
