P = T × ω = 1.96 mN·m × 6,930 rpm = 1.42 W

P: mechanical output power at the rated point
T: rated torque
ω: rated speed, converted to radians per second

The published rated output is 1.42 W. The two agree to rounding; where they differ, the published value governs.

The winding's line, before reduction.

The same relationship at the motor shaft, where the numbers are published rather than carried through a gearhead.

Linear torque-speed approximation for MM-C1636-120B at 12.0 V, from the published no-load speed (8,320 rpm) to the published stall torque (11.9 mN·m). Both endpoints are published values; the line between them is a construction, not a measured curve.

Application fit and cautions

Read out of this record's own numbers.

At its rated point this winding delivers 1.96mN·m at 6,930rpm. That is 1.42 W of mechanical output. Direct drive at that speed suits fans, drums and light continuous rotation; anything that has to hold or position a load needs a reduction, and the gearheads with a reviewed fit are listed above.

A 2D PDF drawing, a DXF and a neutral STEP file are not published for this record today, so there is no link here to a file that does not exist. A configured drawing carries tolerances and interface dimensions we will stand behind, which is why it comes out of a short qualified request rather than a download button.
