Umgomo Wokusebenza we-AC Servo Motor:
Lapho i-AC Servo motor ingenawo amandla okulawula, kukhona kuphela amandla kazibuthe akhiqizwa yi-exparition winding esitimelweni, futhi i-rotor imile. Lapho kukhona i-control voltage, kwakhiqizwa amandla kazibuthe ajikelezayo esitsheni, futhi i-rotor ijikeleza eceleni kwendlela kazibuthe ejikelezayo. Lapho umthwalo uhlala njalo, ijubane lezimoto lishintsha ngobukhulu bamandla okulawula. Lapho isigaba se-voltage control siphambene, i-ac servo motor izocinga. Yize umgomo osebenzayo we-AC Servo motor ufana nalokho kwemoto yesigaba esihlukanisiwe se-asynchronous motor, ukumelana nokuphambuka kwangaphambili kukhulu kakhulu kunalokho okwedlule. Ngakho-ke, uma kuqhathaniswa nemoto ye-asynchronous motor eyodwa, i-servo motor inezici ezintathu ezibalulekile:
1. I-torque enkulu yokuqala
Ngenxa yokumelana okukhulu kwe-rotor, ijika le-torque limical likhonjiswa kwijika le-1 kuMdwebo 3, okusobala okuhlukile kwi-torque isimilo ijika ijika 2 yama-motor ajwayelekile asynchronous. Kungenza isilinganiso esibucayi Slip Slip s0>, esingawenzi kuphela isici se-torque (isimo semishini) esiseduze nomugqa, kepha futhi sine-torque enkulu yokuqala. Ngakho-ke, lapho i-stator ine-control voltage, i-rotor ijikeleza ngokushesha, okunezimpawu zokuqala nokuzwa okuphezulu.
2. Ububanzi obubanzi bokusebenza
3. Akunasimo sokujikeleza
Ngemoto ye-servo ekusebenzeni okujwayelekile, inqobo nje uma i-control voltage ilahlekile, imoto izoyeka ukusebenza ngokushesha. Lapho i-servo motor ilahlekelwa amandla okulawula, isesimweni sokusebenza kwesigaba esisodwa. Ngenxa yokumelana okukhulu kwe-rotor, izici ezimbili ze-torque (T1-S1, T2-S2 Curves) ezikhiqizwe amasimu kazibuthe ezimbili ezijikelezayo ezijikeleza ngezikhombisi eziphambene nesitabane kanye nezimpawu zokwenziwa ze-rotor) nezimpawu zokwenziwa ze-rotor Ijika) amandla okukhipha we-AC Servo Motor ngokuvamile u-0.1-100w. Lapho imvamisa yamandla ingu-50hz, ama-voltages angama-36V, 110V, angama-220, 380v; Lapho imvamisa yamandla ingu-400hz, ama-voltages angama-20v, 26v, 36v, 115V nokunye. I-AC Servo Motor ihamba kahle ngomsindo ophansi. Kepha isimilo se-control singewona umugqa, futhi ngenxa yokuthi ukumelana kwe-rotor kukhulu, ukulahleka kukhulu, futhi ukusebenza kahle kuphansi, kuqhathaniswa ne-DC servo motor yesilinganiso esifanayo, kunzima futhi kulungile, ngakho-ke kufanelekile kuphela ngezinhlelo ezincane zokulawula amandla ze-0.5-100W.
Okwesibili, umehluko phakathi kwe-AC Servo motor ne-DC Servo Motor:
I-DC Servo Motors ihlukaniswe ngama-motor ahlanganisiwe futhi angenamkhawulo. Ama-motors ahlanganisiwe aphansi ngezindleko, alula ngesakhiwo, enkulu ekuqaleni kwe-torque, okulula ukulawula uhla, futhi adinga ukulungiswa, kepha adinga ukulungiswa, akhiqize amandla we-electromagnete, futhi akhiqize izidingo ze- imvelo. Ngakho-ke, ingasetjenziswa emikhakheni ejwayelekile yezimboni kanye nezembango ezizwela izindleko. I-motor engenabhulagule incane ngosayizi, isisindo esisindoni, esikhulu ekuphumeni, ngokushesha ekuphenduleni, ngejubane eliphakeme, lincane nge-inertia, bushelelezi ekujikelezeni kanye nezinzile ku-torque. Ukulawulwa kuyinkimbinkimbi, futhi kulula ukukubona ubuhlakani. Indlela yayo yokuhamba nge-elekthronikhi iyavumelana nezimo, futhi ingaba ngumhambisi wamanzi wesikwele noma ukuguqulwa kwe-sine wave. I-motor ayinasondlo, inokusebenza okuphezulu, izinga lokushisa eliphansi, imisebe ephansi ye-electromagnetic, impilo ende, futhi ingasetshenziswa ezindaweni ezahlukahlukene.
I-AC Servo Motors ihlukaniswe ngama-motor avumelanayo nango-Asynchronous. Njengamanje, ama-motors avumelanayo ajwayele ngokuvamile asetshenziswa ekulawulweni kokunyakaza. Uhla lwayo lwamandla lukhulu futhi lungazuza amandla amakhulu. I-inertia enkulu, isivinini esikhulu sokujikeleza esiphakeme, futhi sinciphe ngokushesha njengoba kukhuphuka kwamandla. Ngakho-ke, ilungele izinhlelo zokusebenza ezisebenza kahle ngejubane eliphansi.
I-rotor ngaphakathi kwe-servo motor inguzibuthe ongapheli. Ugesi we-U / V / W ugesi ezintathu olawulwa ngumshayeli wenza inkambu ye-electromagnetic. I-rotor ijikeleza ngaphansi kwesenzo sale nkambu kazibuthe. Ngasikhathi sinye, i-Encoder yemoto idla isiginali kumshayeli. Amanani aqhathaniswa nokulungisa i-angle lapho i-rotor iphenduka khona. Ukunemba kwemoto ye-servo motor kuya ngokunemba (inani lemigqa) ye-Encoder.
Ngentuthuko eqhubekayo yokuzenzakalela kwezimboni, isidingo se-software ezenzakalelayo kanye nemishini ye-Hardware ihlala iphakeme. Phakathi kwazo, imakethe yamarobhothi ezimboni yezezimboni ibilokhu ikhula ngokuqinile, futhi izwe lami selibe yimakethe enkulu yemfuno enkulu kunazo zonke. Ngasikhathi sinye, ishayela ngokuqondile isidingo semakethe seSerro Systems. Kwezimanje, i-AC ne-DC Servo Motors ene-torque ephezulu, i-torque enkulu ne-inertia ephansi isetshenziswa kabanzi kumarobhothi ezimboni. Amanye ama-motors, afana ne-AC Servo Motors kanye nama-motors we-stepper, azosetshenziswa futhi kumarobhothi ezimboni ngokuya ngezidingo ezihlukile zohlelo lokusebenza.
