RE: [CAD_CAM_EDM_DRO] nema 34 motors on BP series 1 conversion

Well, actually, no.

It is lb*in or oz*in.

That's a multiplication, not a division.

Think of it this way-a shaft needs a certain amount of torque to turn it. I
can apply 1lb at a 2 inch radius, or 2lb at a 1 inch radius. I get 2 lb-in
either way.

The "distance" is not the amount of movement, but the distance from the
center of rotation.

Hope this helps,

Well if you want to get technical it really is lb/in and oz/in. Rotational
torque is rated in this manner. A 2" disc mounted upon a horizontal shaft
and a 1 ounce weight suspend ed from its outer diameter at a horizontal
plane from the axis would constitute 1 ounce of force PER 1" of moment, 1"
moment being the radius. Or 1 oz/in.

I wouldn't care so much if it were not for the possibility that people will
try to use the units quoted in an equation, with the result that they will
be more convinced than ever that this is all black magic.

in*lb(pronounced "inch pounds" or "pound
inches"), NOT lb/in(pounds per inch) or in/lb(inches per pound).

Whew! I feel better now.....
