Hello!
I have asked the few I know who have knowledge of this and now turn to this one inexhaustible source of knowledge aka. the electronics forum.
I was going to buy stepper motors yesterday but got so confused about the spec that I need to get an answer to this first. 2 different stepper motors, quite close in size but with very different spec.

Both Nema17 but the first 1.33A and 22Ncm and the second only 0.4A but almost double the torque.
I can see that the resistance is very much higher on the latter but what's the catch?
Double the torque to 1/3 the current sounds a little too good to be true so what am I missing?
