Servo driver,inozivikanwawo se "servo controller" kana "servo amplifier", imhando yekudzora inoshandiswa kudzora servo motors. Basa rayo rakafanana nere frequency converter inoshanda pane akajairwa AC motors, uye iri chikamu che servo system. Kazhinji, servo motors inodzorwa kuburikidza nenzira nhatu: chinzvimbo, kumhanya, uye torque kuti uwane yakakwirira-chaiyo chinzvimbo cheiyo yekufambisa system.
1, Kurongwa kwe servo motors
Yakakamurwa kuita zvikamu zviviri: DC uye AC servo motors, AC servo motors inokamurwazve kuita asynchronous servo motors uye synchronous servo mota. Parizvino, masisitimu eAC ari kutsiva DC masisitimu zvishoma nezvishoma. Kuenzaniswa neDC masisitimu, AC servo mota dzine zvakanakira sekuvimbika kwakanyanya, yakanaka kupisa kupisa, nguva diki yeinertia, uye kugona kushanda pasi pemamiriro emagetsi. Nekuda kwekushaikwa kwemabhurashi uye giya rekutungamirira, iyo AC yakavanzika server system yave zvakare brushless servo system. Iwo mamotor anoshandiswa mairi ndeye brushless cage asynchronous motors uye anogara magineti synchronous motors.
1. DC servo motors yakakamurwa kuita brushed uye brushless mota
① Brushless mota dzine mutengo wakaderera, chimiro chakareruka, hombe yekutanga torque, yakakura yekumhanyisa mirau renji, kudzora kuri nyore, uye inoda kugadziriswa. Nekudaro, iwo ari nyore kuchengetedza (kutsiva kabhoni mabhurashi), anogadzira kukanganiswa kwemagetsi, uye ane zvinodiwa zvenzvimbo yekushanda. Iwo anowanzo shandiswa mumutengo unobata zvakajairwa maindasitiri uye zvehurumende zvikumbiro;
② Brushless motors ine diki diki, huremu huremu, yakakura kubuda, kukurumidza kupindura, kumhanya, diki inertia, yakagadzika torque uye yakatsetseka kutenderera, yakaoma kudzora, hungwaru, inochinjika yemagetsi commutation nzira, inogona kuita square wave kana sine wave commutation, kuchengetedza mahara, inoshanda uye inochengetedza simba, yakaderera electromagnetic mwaranzi, yakaderera tembiricha kukwira, hupenyu hurefu hwebasa, uye inokodzera nharaunda dzakasiyana.
2, Hunhu hwemhando dzakasiyana dze servo motors
1. Zvakanakira uye zvakaipira zveDC servo motors
Zvakanakira: Yakarurama yekumhanyisa kudzora, yakasimba torque kumhanya maitiro, nyore kudzora musimboti, kushandiswa kuri nyore, uye mutengo unokwanisika.
Zvakaipa: Kuchinja kwebhurashi, kumisa kumhanya, kuwedzera kuramba, chizvarwa chekupfeka zvimedu (zvisina kukodzera nzvimbo dzisina guruva uye dzinoputika)
2. Zvakanakira nekuipira kweAC servo mota
Advantages: Yakanaka kukurumidza kudzora maitiro, yakatsetseka kudzora inogona kuwanikwa mukati mese spidhi renji, inenge isina oscillation, yakanyanya kushanda inopfuura 90%, yakaderera kupisa chizvarwa, yakakwirira-kumhanya kudzora, yakakwirira-chaiyo chinzvimbo chekutonga (zvinoenderana nekurongeka kwe encoder), inogona kuwana nguva dzose torque mukati meiyo yakatemerwa nzvimbo yekushandisa, yakaderera inertia, yakaderera ruzha, hapana kupfeka brashi, kuchengetedza mahara (yakakodzera nzvimbo isina guruva uye inoputika).
Zvakaipa: Kudzora kwakaoma, uye mutyairi paramita inoda kugadziridzwa pa-saiti kuona iyo PID paramita, inoda yakawanda wiring.
Parizvino, mainstream servo madhiraivha anoshandisa dhijitari siginecha processors (DSP) semusimboti wekutonga, iyo inogona kuwana yakaoma kudzora algorithms, digitization, networking, uye hungwaru. Zvishandiso zvemagetsi zvinowanzo shandisa maseketi ekutyaira akagadzirwa ane hungwaru simba modules (IPM) semusimboti. IPM inobatanidza kutyaira matunhu mukati uye inewo kutadza kuona uye kudzivirira maseketi ekuwedzeredza, overcurrent, overheating, undervoltage, etc. Soft start circuits inowedzerwawo kudunhu guru kuti kuderedze kukanganisa kwekutanga kwemutyairi. Iyo magetsi dhiraivha unit inotanga kugadzirisa iyo yekuisa-nhatu-chikamu kana mains simba kuburikidza nematatu-chikamu akazara bhiriji rectifier wedunhu kuti uwane inoenderana DC simba. Mushure mekugadzirisa, iwo matatu-chikamu kana mains simba rinoshandiswa kutyaira matatu-chikamu chisingaperi magineti synchronous AC servo mota kuburikidza nenhatu-chikamu sine PWM voltage sosi inverter yekushandurwa frequency. Iyo yese maitiro eiyo magetsi drive unit inogona kungotsanangurwa senge AC-DC-AC maitiro. Iyo huru topology dunhu reiyo rectifier unit (AC-DC) idanho-nhatu rakazara bhiriji risingadzoreki rectifier redunhu.
1. Mutyairi wiring
Iyo servo drive inonyanya kusanganisira kutonga wedunhu magetsi, main control circuit magetsi, servo inobuda magetsi, controller yekupinda CN1, encoder interface CN2, uye yakabatana CN3. Iyo yekudzora wedunhu simba rekupa imwe-chikamu AC simba rekupa, uye iyo yekupinza simba inogona kuve imwe-chikamu kana matatu-chikamu, asi inofanira kunge iri 220V. Izvi zvinoreva kuti kana matatu-phase yekupinda ichishandiswa, yedu-yechikamu chetatu magetsi inofanira kubatanidzwa kuburikidza netransformer transformer. Kune vatyairi vakaderera-simba, inogona kufambiswa zvakananga muchikamu chimwe chete, uye imwe-chikamu chekubatanidza nzira inofanira kubatanidzwa kune R uye S terminals. Rangarira kusabatanidza iyo servo mota inobuda U, V, uye W kune iyo huru yedunhu magetsi, sezvo inogona kupisa mutyairi. Iyo CN1 chiteshi inonyanya kushandiswa kubatanidza iyo yepamusoro komputa controller, ichipa yekupinda, inoburitsa, encoder ABZ matatu-chikamu kubuda, uye analog kubuda kweakasiyana masaini ekutarisa.
2. Encoder wiring
Kubva pamufananidzo uri pamusoro, zvinoonekwa kuti isu takangoshandisa 5 kubva pamapfumbamwe materminals, anosanganisira imwe yekudzivirira waya, waya mbiri dzemagetsi, uye maviri serial ekutaurirana masaini (+-), ayo akafanana newaya encoder yedu yakajairwa.
3. Chiteshi chekukurukurirana
Mutyairi akabatana nemakomputa ekumusoro akadai sePLC neHMI kuburikidza neCN3 port, uye anodzorwa kuburikidzaMODBUS kutaurirana. RS232 uye RS485 inogona kushandiswa kutaurirana.
