Torque Calculator

The thrust required is an important variable in determining the linear motion product right for the system. It is useful to determine the output torque needed from a motor to produce the appropriate linear thrust.

The formula below is used to find the required motor rotary torque, give the Force, lead, and efficiency of the lead screw.

ACME lead screw efficiency range: 20% - 80%

Ball screw efficiency range: 85 - 95%
