Ulwazi Lomkhiqizo
Isethulo esifushane Sesimiso Sokusebenza se-Servo Drive
Isebenza kanjani i-Servo Drive
Njengamanje, amadrayivu e-servo ajwayelekile wonke asebenzisa iphrosesa yesiginali yedijithali (i-DSP) njengomongo wokulawula, ongakwazi ukubona ama-algorithms okulawula ayinkimbinkimbi futhi abone ukwenziwa kwedijithali, ukuxhumana nobuhlakani.Amadivayisi kagesi ngokuvamile asebenzisa isekethe yedrayivu eklanywe ngemojula yamandla ehlakaniphile (IPM) njengomongo.Isekethe yedrayivu ihlanganiswe ku-IPM, futhi inokutholwa kwephutha nokuvikela amasekhethi afana nokugcwala ngokweqile, i-overcurrent, ukushisa ngokweqile, kanye nokungabi namandla kwamandla.Isekhethi yokuqalisa ethambile iphinde yengezwe kusekethe enkulu ukuze kuncishiswe umthelela wenqubo yokuqalisa kudrayivu.
Incazelo Yomkhiqizo
Imikhiqizo ye-Schneider Electric isetshenziswa ezinhlobonhlobo zezimakethe zamandla:
1.Imithombo yamandla avuselelekayo
2.Ingqalasizinda namandla
3.Industrial automation
4.Indawo yokuhlala ehlakaniphile
5.Uhlelo Lokuphatha Izakhiwo
6.Impahla yomkhiqizo wokusabalalisa
Izici Zomkhiqizo
Iyunithi yedrayivu yamandla iqala ngokulungisa amandla okokufaka ezigaba ezintathu noma amandla amapayipi ngokusebenzisa isifunda sokulungisa kabusha ibhuloho eligcwele lezigaba ezintathu ukuze kutholwe amandla akhona ahambisanayo.Ngemuva kokuthi amandla ezigaba ezintathu noma amandla amapayipi elungisiwe, isiguquli se-voltage se-sinusoidal PWM sezigaba ezintathu sisetshenziswa ukushayela injini yezigaba ezintathu unomphela uzibuthe we-AC servo motor.Yonke inqubo yeyunithi yokushayela amandla ingashiwo nje ukuthi iyinqubo ye-AC-DC-AC.Isekhethi ye-topology eyinhloko yeyunithi yokulungisa (AC-DC) iyisekhethi yesigaba ezintathu esigcwele ibhuloho elingalawuleki lesilungisi.
Ngokusetshenziswa okukhulu kwezinhlelo ze-servo, ukusetshenziswa kwamadrayivu e-servo, ukulungisa iphutha kwe-servo drive, nokugcinwa kwe-servo drive yizinkinga ezibalulekile zobuchwepheshe zamadrayivu e-servo namuhla.Abahlinzeki abaningi ngokwengeziwe bamadivayisi okulawula izimboni benze ucwaningo olujulile lobuchwepheshe kumadrayivu e-servo.
Amadrayivu e-servo asebenza kahle ayingxenye ebalulekile yokulawula ukunyakaza kwesimanje futhi asetshenziswa kakhulu kumishini ezishintshayo njengamarobhothi ezimboni kanye nezikhungo zemishini ye-CNC.Ikakhulukazi, amadrayivu e-servo asetshenziselwa ukulawula ama-motor synchronous kazibuthe ahlala njalo e-AC asephenduke indawo yocwaningo ekhaya naphesheya.Ama-algorithms amanje, isivinini, kanye nesikhundla sesi-3 sokulawula iluphu evaliwe esekelwe kulawulo lwe-vector avame ukusetshenziswa ekwakhiweni kwe-AC servo motor.Ukuthi idizayini yesivinini esivaliwe iluphu ku-algorithm inengqondo noma ayidlala indima ebalulekile kusistimu yokulawula i-servo, ikakhulukazi ekusebenzeni kokulawula isivinini.
