Ukuqhathaniswa okujulile phakathi kwemoto encane ye-stepper kanye nemoto i-N20 DC: nini ukukhetha i-torque nokuthi nini ukukhetha izindleko?

Enqubweni yokuklama imishini enembile, ukukhetha umthombo wamandla kuvame ukunquma impumelelo noma ukwehluleka kwephrojekthi yonke. Lapho isikhala sokuklama silinganiselwe futhi kudingeka kwenziwe ukukhetha phakathi kwama-motor ama-micro stepper kanye nama-motor e-N20 DC atholakala yonke indawo, onjiniyela abaningi kanye nabaphathi bokuthenga bazocabanga ngokujulile: ingabe kufanele balandele ukulawula okunembile kanye ne-torque ephezulu yama-motor e-stepper, noma bakhethe inzuzo yezindleko kanye nokulawula okulula kwama-motor e-DC? Lona akuyona nje umbuzo wezobuchwepheshe onezinketho eziningi, kodwa futhi yisinqumo sezomnotho esihlobene nemodeli yebhizinisi lephrojekthi.
