How to calculate motor drive torque for ball screws

May 18 2016 0183 32 In ball screw terminology we commonly refer to lead which is the linear distance the screw moves for every complete rotation rather than pitch which is the linear distance between screw threads The equation for drive torque Td = Fa P / 2000 π η demonstrates that torque T is directly proportional to the lead of the screw P...

Converting Between Linear Force and Torque of a Ballscrew

Converting Between Linear Force and Torque of a Ballscrew Force = Torque x 2 x PI x gear reduction ratio / Lead x eff Torque = Force x Lead / 2 x PI x gear reduction ratio x eff Derivation If you know the torque applied to a ballscrew then you can calculate the linear force produced by the ballscrew...
