Ciao a tutti. i've built steel structures for nema23 stepper motor reelers (don't know if the word is exact, intended a drum to roll a wire on..). i've 4 of these motors, to setup an inverted tetrapod. (for those who followed me, i used this to make a volleyball fly in the air...just artistic purpose.) Now i would like to improve a little this system power, so i'm going to ask you an help, for i know your knowledge is huge.
so, the nema23 i'm using are (on paper):rated current 2,8A , 4 wire and have a holding torque of 12,6 kgf/cm (175 oz/in). the calculated holding torque after the gear demult. and the drum diameter is 5,4 kg. in fact each motor has a gear set which doubles the power, and the drum is 5 cm radius. so 12,6 * 2 / 5. in the real world (with friction ect..) i've proven that when moving the max weight i can apply on each motor is around 1,3 kg. i would like to know if you know about nema23 motors (either stepper or servo) with more (kind of double..) torque. I'm asking about nema23, because in this way i don't need to change the structure, just need to exchange motors.. any idea? By the way, we did another show with this motors, in which we made a magic ball and a microphone fly! as soon as possible i'll post videos. ciao!! ------------------------------------------------------------------------------ Beautiful is writing same markup.
