I need to choose my stepper motors and followed the following logic - I'd appreciate any pointers/corrections.
Given my desired feedrate and force (0.1m/s and 50kgf) I calculate the final power (50Watts). Factor in gearing losses by multiplying by 2, for 100W.
Once I find a motor giving at least that power, I check the datasheet and set the gear ratio such that the motor's 'corner speed' provides the feedrate desired.
(for 'corner speed' see Support)
Sorry if this isn't the right forum, I couldnt find a stepper forum
