Our electric driver FED II 10K attains the high torque by reducing its rotation speed to 1/10 with planet gears. The planet gear has a defect that a scar of a tooth injures another tooth meshing with and that scars are apt to spread all over the gear. The mesh of these teeth with scar has the influence on torque curves of tightening screw. Therefore, we cannot judge whether measured data reflect the characteristic of teeth's mesh or that of a electric driver, unless we change the teeth's mesh in every measurement. In this work, we tightened and loosened screws 480 times with the FED II 10K, and appreciated how many data are needed at fewest to get reliable characteristics of the driver.
