On a more simplified matter - in order for the motor to rotate the 1.5 pound load attached to it, assume a maximum of 2 lbs including friction forces, how would one calculate the torque required to rotate said load at that speed? EDIT: Power can be up to 40 Watts available

If not a scotch yoke, what would be a typical method of driving a machine like this?

There will not be a cutting board. There will be a rotating "mop-head" like system to sweep the cut leaves behind the saw and onto a conveyer belt. If you would like, I can provide images of a similar product that resembles the action I am trying to accomplish.

Apologies for leaving out that information. This will be for cutting leafy-greens grown on a 30-inch bed.

Apologies for leaving those fine details out. This will be for a leafy-green plant harvesting mechanism. The motor will be operated at 12V - size, current, and power can be decided after the fact. This is mostly risk reduction protocol I am taking at the moment to see how well the scotch-yoke...

This will be cutting leafy greens, 30 inches of saw blade and 30 inch bed of leafy greens. For simplicity sake let's just focus on the weigh of the blade and less so on the actual cutting, as I am mostly trying to calculate specs for the motor to simply move the saw blade at a desired speed.

If I calculate the load torque as simply the force multiplied by the radius - 1.5lb-in in this case - does that mean this is also the torque rating required by the motor to achieve 700 RPM?

I am designing a reciprocating saw that I plan to use a scotch-yoke mechanism to convert rotational kinetic energy into linear kinetic energy. I want to spec out a motor and the final thing I need to calculate is the required torque. The motor must be 12 Volts and I need to know the required...
