Application fit and cautions

Read out of this record's own numbers.

At its rated point this winding delivers 0.29mN·m at 7,110rpm. That is 0.22 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.
