    Depends greatly on the size of your machine, are you using ballscrews/ACME etc. With only 24v you want a motor with very low inductance to get any reasonable speed.
    reccomended v=32*L^0.5, so rearranging that:
    L=(24/32)^2=0.56mH
    So your looking for a motor with an inductance ideally lower than 0.56mH, and sufficient torque...you'll be lucky to meet those criteria so just find as close as possible.

    Hope that helps...
