He wāhanga tino nui te mana o te mōta i runga i tePūreretā 3D, ko tōna tika e pā ana ki te pai, te kino rānei o te pānga tā 3D, ko te tikanga he whakamahi i te motuka stepper mō te tā 3D.
Nō reira, kei reira ētahi pūreretā 3D e whakamahi ana i ngā motuka servo? He tino rawe, he tika hoki, engari he aha e kore ai e whakamahia ki ngā pūreretā 3D noa?
Kotahi te ngoikoretanga: he nui rawa te utu! Ki te whakaritea ki ngā pūreretā 3D noa, kāore e tika ana. Mena he pai ake mō ngā pūreretā ahumahi, he rite tonu, engari ka taea te whakapai ake i te tika.
I konei ka tangohia e mātou ēnei motuka e rua, he tātaritanga whakatairite taipitopito kia kite ai he aha te rerekētanga.
Ngā whakamāramatanga rerekē.
Mōta hikoihe taputapu nekehanga motuhake, he rerekē i te AC noa, ā,Ngā motuka DC, ka huri te motuka noa ki te hiko, engari ehara te motuka stepper i te motuka stepper, ko te motuka stepper te mea hei whiwhi whakahau ki te mahi i tētahi taahiraa.
Ko te motuka servo te miihini e whakahaere ana i te mahi o ngā wāhanga miihini i roto i te pūnaha servo, ka taea te whakarite i te tere whakahaere me te tika o te tūranga, ā, ka taea te huri i te tohu ngaohiko ki te taipana me te tere hei taraiwa i te mea whakahaere.
Ahakoa he rite tonu te aratau whakahaere o ngā mea e rua (aho pāorooro me te tohu aronga), he rerekētanga nui kei roto i te whakamahinga o te mahi me ngā wā tono. He whakataurite i te whakamahinga o te mahi a ngā mea e rua.
He rerekē te tika o te whakahaere.
Wāhanga-ruamōtini stepper ranuKo te koki taahiraa he 1.8°, 0.9° te nuinga
Ko te tika o te whakahaere o tētahi motuka servo AC ka whakamanahia e te encoder hurihuri kei muri o te pou motuka. Hei tauira, mō tētahi motuka servo AC mamati katoa a Panasonic, mō tētahi motuka me te encoder raina-2500 paerewa, ko te ōrite o te pāorooro he 360°/10000=0.036° nā te hangarau auau whā e whakamahia ana i roto i te puku.
Mō te mōtini me te encoder 17-bit, ka whiwhi te puku i te 217=131072 ngā pātere mō ia hurihanga mōtini, ko te tikanga ko tōna pātere ōrite he 360°/131072=9.89 hēkona, arā, 1/655 o te pātere ōrite o te mōtini stepper me te koki hikoinga o te 1.8°.
Ngā āhuatanga auau-iti rerekē.
Ka puta he āhuatanga wiri auau-iti i te tere iti o te motuka stepper. E pā ana te auau wiri ki te āhua o te kawenga me te mahi a te puku, ā, e kiia ana ko te haurua o te auau tīmatanga kore-kawenga o te motuka.
He tino kino tēnei āhuatanga wiri auau-iti e whakatauhia ana e te mātāpono mahi o te motuka stepper ki te mahi noa o te mīhini. Ina mahi ngā motuka stepper i ngā tere iti, me whakamahi te hangarau whakaiti i te auau hei whakakore i te āhuatanga wiri auau-iti, pērā i te tāpiri i ngā whakaiti i te auau ki te motuka, te whakamahi rānei i te hangarau wehewehe i te puku.
He tino maeneene te oma o te motuka servo AC, ā, kāore e wiri ahakoa i ngā tere iti. He mahi pehi haruru kei te pūnaha servo AC, ka taea te hipoki i te kore pakari o te mīhini, ā, he mahi whakatau auau ā-roto kei te pūnaha, ka taea te kite i te pūwāhi haruru o te mīhini, me te whakahaere i te whakatikatika pūnaha.
Te mahi rerekē o te mahi.
Ko te mana whakahaere o te motuka stepper he mana whakatuwhera-koropiko, he nui rawa te auau tīmatanga, he nui rawa rānei te kawenga ka pāngia e te āhuatanga o te ngaro o ngā hikoinga, te aukati rānei. He nui rawa te tere ka pāngia e te tere nui rawa ina mutu, nō reira, kia tika ai te whakahaere, me aro ki te raruraru o te tere piki me te heke.
Mā te pūnaha taraiwa servo AC ka taea te whakahaere i te tohu urupare encoder motuka, ka taea e te taraiwa te whakamātautau tika i te hanganga o roto o te koropiko tūranga me te koropiko tere, i te nuinga o te wā ka puta he āhuatanga ngaronga taahiraa, he ngaronga rānei o te motuka stepper, he pono ake te mahi whakahaere.
Hei whakarāpopototanga, he pai ake te pūnaha servo AC i te motuka stepper i roto i ngā āhuatanga maha. Engari i ētahi wā kāore i te tino uaua ka whakamahia te motuka stepper hei mahi i te motuka. He iti ake te uaua o te mīhini tā 3D, ā, he tino utu nui te motuka servo, nō reira ko te motuka stepper te whiringa whānui.
