1. Tikanga mahi o te taraiwa servo:
I tenei wa, ko nga taraiwa servo auraki e whakamahi katoa ana i te tukatuka tohu tohu mamati (DSP) hei matua whakahaere, ka taea te mohio ki te mana whakahaere algorithm, me te mohio ki te whakarorohikotanga, te whatunga me te matauranga.Ko nga taputapu hiko e whakamahi ana i nga waahanga hiko mohio (IPM) hei hoahoa matua o te ara iahiko puku, IPM roto iahiko puku whakauru, a he overvoltage, overcurrent, overheating, undervoltage me etahi atu ara iahiko whakamarumaru he, i roto i te ara iahiko matua ka taapirihia ano te ara iahiko tiimata ngawari. , hei whakaiti i te paanga o te tukanga timatanga ki te taraiwa.Ko te waahanga taraiwa hiko ka whakatika tuatahi i te whakaurunga toru-waahanga, hiko matua ranei na roto i te toru-waahanga piriti whakatika arataki kia whiwhi i te naianei tika.Ko te toru-waahanga aukume tuturu tukutahi AC servo nekeneke e peia e te toru-wahanga sinusoidal ngaohiko inverter PWM.Ko te tukanga katoa o te waahanga taraiwa hiko ka taea te korero noa ko te tukanga AC-DC-AC.Ko te ara iahiko topological matua o AC-DC ko te toru - wahanga ki tonu - piriti ara iahiko whakatika kore whakahaere.
Na te whakamahinga nui o te punaha servo, te whakamahi i te taraiwa servo, te taraiwa taraiwa, te tiaki i te taraiwa he mea nui ake nga kaupapa hangarau i roto i te taraiwa o tenei ra, ka nui ake nga kaiwhakarato ratonga hangarau whakahaere ahumahi i runga i te hangarau taraiwa servo rangahau hohonu. .
Ko te taraiwa Servo tetahi waahanga nui o te whakahaere nekehanga hou, e whakamahia nuitia ana i roto i nga miihini ahumahi me nga pokapū miihini CNC me etahi atu taputapu automation.Ina koa, ko te taraiwa servo e whakamahia ana ki te whakahaere i te motuka hiko tukutahi aukume tuuturu kua noho hei waahi rangahau i te kaainga me o waho.Naianei, tere, tuunga 3 katia-koropiko mana hātepe i runga i te mana vector e whakamahia nuitia ana i roto i te hoahoa taraiwa AC servo.Ahakoa he whaitake te hoahoa kati-koropiko tere i roto i tenei algorithm, kaore ranei he mahi nui i roto i te punaha whakahaere servo katoa, ina koa i roto i nga mahi o te mana tere.
2. Atekōkiri Servo:
Hei waahanga nui o te whakahaere nekehanga hou, ka whakamahia nuitia i roto i nga miihini ahumahi me nga pokapū miihini CNC me etahi atu taputapu automation.Ina koa, ko te taraiwa servo e whakamahia ana ki te whakahaere i te motuka hiko tukutahi aukume tuuturu kua noho hei waahi rangahau i te kaainga me o waho.Naianei, tere, tuunga 3 katia-koropiko mana hātepe i runga i te mana vector e whakamahia nuitia ana i roto i te hoahoa taraiwa AC servo.Ahakoa he whaitake te hoahoa kati-koropiko tere i roto i tenei algorithm, kaore ranei he mahi nui i roto i te punaha whakahaere servo katoa, ina koa i roto i nga mahi o te mana tere.
I roto i te tere kati-koropiko o te taraiwa servo, he mea tino nui te tika o te inenga tere o te rotor motopaika ki te whakapai ake i nga ahuatanga hihiri me te pateko o te mana tere o te tere tere.Kia kitea ai te toenga i waenga i te tika o te ine me te utu o te punaha, ka whakamahia te encoder photoelectric incremental hei pūoko ine tere, a ko te tikanga ine tere he M/T.Ahakoa he tika te ine me te whanui whanui o te tachometer M/T, kei a ia ano ona koha, tae atu ki: 1) me kitea kia kotahi te iti rawa o te putere kōpae waehere katoa i roto i te waa ine, ka whakawhāitihia te iti o te tere ine;2) He uaua mo nga huringa taima o nga punaha whakahaere e rua e whakamahia ana mo te ine tere ki te pupuri i te tino tukutahitanga, kaore e taea te whakamana i te tika o te ine tere i nga waa ine me nga huringa tere nui.Na reira, he uaua ki te whakapai ake i te mahi o te tere taraiwa servo e whai ake nei me te whakahaere ma te whakamahi i te tikanga hoahoa whakahiato tere.
Ētahi atu kōrero:
I. Apure tono:
Kei te whakamahia te puku Servo i roto i te waahi o te miihini werohanga miihini, miihini kakano, miihini miihini, miihini miihini CNC me etahi atu.
Ii.Rerekētanga e hāngai ana:
1. Ka taea e te kaiwhakahaere servo te whakarereke i te waahanga mahi me te waahanga papaahi ma te atanga aunoa.I te wa ano, ka whakamahia nga momo momo papaahi ki te whakatutuki i nga momo whakahaere rereke (RS232, RS485, muka whatu, InterBus, ProfiBus), me te aratau mana o te kaitahuri auau whanui he mea kotahi.
2. Ko te kaiwhakahaere servo e hono tika ana ki te hurihuri hurihuri, ki te encoder ranei hei hanga i te katinga kati o te tere me te mana neke.Engari ka taea e te kaitahuri o te ao te hanga i tetahi punaha whakahaere kopae tuwhera.
3. He pai ake ia taurangi mana (pēnei i te tika o te ahua me te mahi hihiri, me etahi atu) o te kaiwhakahaere servo i tera o te kaitahuri auau whanui.
