Match torque and speed over time
Compare rated and peak values with the actual motion profile, including peak duration, repetition, acceleration, and thermal conditions. Do not size from peak torque alone.

Planetary integrated joint actuator
82 Nm peak planetary joint actuator, 36:1 ratio: MGA-PJ-72-10-36
Both Model 1 and Model 2 are populated, and the source gives both a 36:1 ratio. The visible table still lists separate electrical and output values, so compare the complete columns rather than assuming the labels mean interchangeable options. Model 1 is listed at 82 Nm peak torque and 64 rpm peak speed.
What changes between Model 1 and Model 2 when both columns use a 36:1 ratio?

Verified fact
What this catalogue record confirms
MGA-PJ-72-10-36 is identified in the supplied product literature as a planetary integrated joint actuator. The specification tables below retain the source's Model 1 and Model 2 labels and every listed field.
- Standard configuration has no through-bore and does not support a brake.
- Standard communication supports CAN bus; EtherCAT/CAN FD can be customized.
- The source notes a 100KV version; confirm its exact configuration and lead time with sales before ordering.
- The standard configuration has no water-resistance protection. Contact sales before ordering if needed.

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

The catalogue labels its columns Model 1 and Model 2 but does not define the difference between them. Both labels are retained as published. A source dash or unpopulated cell is presented as “Not specified in source.”

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-PJ-72-10-36 frequently asked questions
What torque and speed does MGA-PJ-72-10-36 list?
Model 1 lists 27 Nm rated torque and 82 Nm under the source label “Peak torque (>3 s),” with 30 RPM rated speed and 64 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 catalogue labels its columns Model 1 and Model 2 but does not define the configuration difference. This page preserves both columns as printed. Confirm the intended build before choosing a 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.
