How much reasoning for 86 stepper motor 6nm? How to calculate the transmission capacity of stepper motor?
86 screw stepper motor transmission capacity analysis:
The main reference parameters are integrated stepper motor output torque and screw pitch. Friction coefficient (t-screw friction coefficient is relatively large, ball screw friction coefficient is relatively small).
The following samsr motor takes 86 integrated stepper motor, static torque 6nm as an example, linear stepper motor axial force (thrust) calculation formula: torque = axial force (thrust) x lead / 2πn (n is efficiency).
Example: linear motor static torque 1nm, linear motor lead 8mm, motor efficiency 80%, calculate thrust 1=fx0.008/2πx80%f=628n converted into the weight that can push the item: weight = 628/gxf (f is the friction coefficient)≈ 30kg, that is, the thrust of the 1nm linear stepper motor is 628n, which can drive about 30-40kg items. Therefore, the thrust of 6nm of 86 stepper motor is about 180~240kg.
