Ulwazi Lomkhiqizo
Isebenza kanjani i-Servo Drive?
Isimiso sokusebenza se-servo drive isilawuli esisetshenziselwa ukulawula i-servo motor, futhi umsebenzi wayo ufana nowokuguqulela imvamisa osebenza kumotho ye-AC evamile.Iyingxenye yesistimu ye-servo futhi isetshenziselwa kakhulu izinhlelo zokubeka ezinembayo eziphezulu.
1. Iyini i-servo drive nokuthi isebenza kanjani?
Uyazi ukuthi i-servo drive isebenza kanjani?Njengamanje, amadrayivu e-servo ajwayelekile wonke asebenzisa amaphrosesa wesignali yedijithali njengomongo wokulawula, ongaqaphela ama-algorithms okulawula ayinkimbinkimbi futhi abone ukwenziwa kwedijithali, ukunethiwekha kanye nobuhlakani.Amadivayisi kagesi ngokuvamile asebenzisa amasekhethi okushayela agxile kumamojula wamandla ahlakaniphile.Isekethe yedrayivu ihlanganiswe ku-IPM futhi inamasekhethi okutholwa kwephutha nokuvikela, afana nokugcwala ngokweqile, i-overcurrent, ukushisa ngokweqile kanye nokungabi namandla kwamandla.Isekhethi yokuqala ethambile nayo yengezwa kuluphu eyinhloko.
Ukuze kuncishiswe umthelela wenqubo yokuqalisa kumshayeli, iyunithi yokushayela amandla iqala ngokulungisa amandla okufakwayo ezigaba ezintathu noma amandla amapayipi ngokusebenzisa isifunda sokulungisa ibhuloho eligcwele lezigaba ezintathu ukuze kutholwe amandla ahambisanayo aqondile.Ngemuva kwezigaba ezintathu ze-AC noma ukulungiswa kwamapayipi amakhulu, isiguquli se-voltage ye-sine wave PWM yezigaba ezintathu sisetshenziselwa ukushayela injini yezigaba ezintathu unomphela uzibuthe we-AC servo motor.Yonke inqubo yeyunithi yokushayela amandla ingashiwo nje ukuthi iyinqubo ye-AC-DC-AC.
Ngokusetshenziswa okukhulu kwezinhlelo ze-servo, ukusetshenziswa kwamadrayivu e-servo, ukulungisa iphutha kwe-servo drive kanye nokugcinwa kwe-servo drive yizinkinga ezibalulekile zobuchwepheshe zokuzenzakalela kukagesi wezimboni kumadrayivu e-servo anamuhla.
Izici Zomkhiqizo
Amadrayivu e-Servo ama-AC servo motors asetshenziswa kabanzi
Amadrayivu e-Servo ayingxenye ebalulekile yokulawula ukunyakaza kwesimanje futhi asetshenziswa kakhulu kumishini ezishintshayo, ikakhulukazi amadrayivu e-servo asetshenziselwa ukulawula amamotho ayizibuthe anomphela we-AC asephenduke indawo eshisayo yocwaningo lwamanje.
