Haeba re batla hore stepper e tsamaee 400 mm ka 600 revolutions ka motsotso, re ka bala palo ea pulse le maqhubu ao OP e lokelang ho a romela?
Re ka laola lebelo la enjene ea stepper joang (ke hore, re bala lebelo la pulse):
Ho nka hore maemo ke likaroloana tse 'nè tse ntle, palo ea li-pulse tse hlokahalang bakeng sa motlakase ho etsa phetoho e le' ngoe, ke hore, 800, ho finyella lebelo la motlakase oa 600 rpm, palo ea maqhubu a maqhubu a lokelang ho romeloa ke moeti. komporo:
Khopolo ea maqhubu ke palo ea likhahla tse rometsoeng ka motsotsoana o le mong.
Kahoo, pele u bala palo ea liphetohelo motsotsoana oa motor stepper
600/60 = liphetohelo tse 10 motsotsoana
Ebe u bala palo ea likhahla tse hlokahalang bakeng sa 10 revolutions / sec.
10 X 800 = 8000
Ke hore, maqhubu a pulse ke 8000, kapa 8K.
Qetello, e le ho hlokomela lebelo la lebelo la 600 rpm, komporo e amohelang e lokela ho boloka maqhubu a pulse a 8K.
Jwale na o ya utlwisisa? Bakeng sa ho bala maqhubu a pulse o tlameha ho tseba lintlha tse peli tse hlokahalang:
1, tseba palo ea likhahla tse hlokahalang bakeng sa phetoho e le 'ngoe ea mochini oa stepper;
2, tseba lebelo la ho potoloha ha enjene ea stepper, yuniti ea lebelo la ho potoloha ke: liphetohelo ka bonngoe
Mokhoa oa ho bala palo ea li-pulses tse hlokoang ke mochini oa stepper.
Ho nka hore ho hlophisoa ke likaroloana tse 'nè tse ntle, palo ea li-pulse tse hlokahalang hore motlakase o fetole selikalikoe ke 800, le ho hlokomela hore stepper motor e tsamaea sebaka sa 400 mm, palo ea palo ea maqhubu a lokelang ho romelloa ke k'homphieutha e ka holimo:
Haeba phallo ea shaft ea enjene ea stepper le screw (sekontiri: 10mm) khokahano e tobileng, kapa ka koloi ea pulley, selika-likoe sa mabili a 10mm. Ke hore, stepper motor ho retelehela selikalikoe, bolelele ba mechine tsamaea 10mm.
Palo ea maqhubu a phetoho e le 'ngoe ea enjene ke 800, ebe bolelele ba ho tsamaea ha pulse:
10mm / 800 = 0.0125 limilimithara
Palo ea likhahla tse hlokahalang ho tsamaea 400mm:
400 / 0.0125 = 32000 pulses
Qetello, e le ho lemoha sebaka sa 400 mm se tsamaisoang ke stepper motor, palo ea li-pulse tse lokelang ho romelloa ke k'homphieutha e amohelang ke 32000.
O ya utlwisisa jwale? Lintho tse tharo tse hlokahalang tse lokelang ho tsejoa e le ho bala palo ea li-pulses ke:
1, tseba palo ea likhahla tse hlokahalang bakeng sa phetoho e le 'ngoe ea mochini oa stepper;
2, tseba motor stepper ho fetola selikalikoe sa bolelele ba ho tsamaea;
3, tseba bolelele bohle ba leeto le hlokoang ke mochini oa stepper;
Haeba re batla ho ntlafatsa ho nepahala, re ka eketsa karohano, haeba karohano e behiloe ho 64 Palo ea maqhubu a hlokahalang bakeng sa phetoho e le 'ngoe ea motlakase ke:

Bolelele ba pulse e tsamaileng ke:
10mm / 12800 = 0.00078 limilimithara
Palo ea likhahla tse hlokahalang ho tsamaea 400 mm:
400 / 0.00078 = 512000 pulses
Ho fihlela lebelo la 600 rpm, maqhubu a maqhubu a lokelang ho romelloa ke komporo e amohelang ke:
