hello
is there someone who could help me understanding something about nema 3phase industrial motor?

for example: where I can find information about key dimension for each motor frame?

check out Kelinginc.com they usually have the specs for most of the stepper motor frame sizes.

thanks
but I didn't refer to these motors

I refer to motor like this
for example

Hello
Hope this helps
Whenever I need a nema frame size chart I go to www.graingers.com
in the search box type " page 6 " There is a pdf of all nema and meteric motor frame dims there..
Good luck
