Unit confusion; RPM and Strokes per minute.

  1. Oct 27, 2011 #1
    I know power = Torque x angular velocity (rad/s) AND
    I am wondering if angular velocity can be calculated through strokes per minute?

    The product is a reciprocating saw (not orbital).

    In this case are RPM's the same as SPM'S?

    Welcome to the PF.

    Do you know what the mechanism looks like to convert the spinning motor shaft into the reciprocating motion of the saw blade? Is there any gearing involved?
