Kodi servo drive imagwira ntchito bwanji:
Pakalipano, ma servo drives amagwiritsa ntchito ma digito a digito (DSP) ngati maziko owongolera, omwe amatha kuzindikira njira zowongolera zovuta ndikuzindikira ma digito, ma network ndi luntha.Zida zamagetsi nthawi zambiri zimatenga gawo loyendetsa lomwe limapangidwa ndi Intelligent Power module (IPM) ngati maziko.Yambitsani dera kuti muchepetse kukhudzidwa kwa dalaivala panthawi yoyambira.
Gawo loyendetsa magetsi limakonza kaye mphamvu ya magawo atatu kapena mphamvu ya mains kudzera pagawo la magawo atatu amtundu wodzaza mlatho kuti mupeze mphamvu yofananira ya DC.Pambuyo pokonzanso magawo atatu magetsi kapena mains magetsi, magawo atatu okhazikika maginito synchronous AC servo motor imayendetsedwa ndi kutembenuka kwafupipafupi kwa magawo atatu a sinusoidal PWM voltage inverter.Njira yonse ya gawo loyendetsa mphamvu imatha kunenedwa kuti ndi njira ya AC-DC-AC.Dera lalikulu la topological la rectification unit (AC-DC) ndi gawo la magawo atatu lodzaza mlatho wosalamulirika.
Ndi kugwiritsa ntchito kwakukulu kwa machitidwe a servo, kugwiritsa ntchito ma servo drives, servo drive debugging, ndi servo drive kukonza zonse ndizofunikira zaukadaulo zamagalimoto a servo masiku ano.Ochulukirachulukira opereka chithandizo chaukadaulo wamafakitale achita kafukufuku waukadaulo wama servo drives.
Ma servo drives ndi gawo lofunikira pakuwongolera koyenda kwamakono ndipo amagwiritsidwa ntchito kwambiri pazida zamagetsi monga maloboti akumafakitale ndi malo opangira makina a CNC.Makamaka servo pagalimoto ntchito kulamulira AC okhazikika maginito synchronous galimoto wakhala kafukufuku hotspot kunyumba ndi kunja.Ma algorithms apano, liwiro, ndi malo 3 otsekera-loop kutengera kuwongolera vekitala amagwiritsidwa ntchito popanga ma AC servo drives.Kaya liwiro lotsekeka lotsekeka mu algorithm iyi ndiloyenera kapena ayi limagwira ntchito yofunika kwambiri pakuwongolera dongosolo lonse la servo, makamaka kuyendetsa liwiro.
Zofunikira za Servo drive system:
1. Wide liwiro osiyanasiyana
2. Kulondola kwa malo apamwamba
3. Zokwanira kufala kukhazikika komanso kukhazikika kwachangu.
4. Pofuna kutsimikizira zokolola ndi kukonza bwino,kuwonjezera pa kufuna kulondola kwa malo apamwamba, makhalidwe abwino oyankhira mofulumira amafunikiranso, ndiko kuti, kuyankha kwa zizindikiro zotsatila malamulo kumafunika kukhala mofulumira, chifukwa dongosolo la CNC limafuna kuwonjezera ndi kuchotsa poyambira ndi braking.Kuthamangako ndi kwakukulu kokwanira kufupikitsa nthawi ya kusintha kwa dongosolo la chakudya ndikuchepetsa cholakwika cha kusintha kwa contour.
5. Kuthamanga kochepa ndi torque yayikulu, mphamvu yodzaza kwambiri
Nthawi zambiri, dalaivala wa servo ali ndi mphamvu yochulukira kuposa nthawi 1.5 mkati mwa mphindi zingapo kapena theka la ola, ndipo imatha kulemedwa ndi 4 mpaka 6 munthawi yochepa popanda kuwonongeka.
6. Kudalirika kwakukulu
Zimafunika kuti makina oyendetsa makina a CNC akhale odalirika kwambiri, okhazikika ogwirira ntchito, kusinthasintha kwamphamvu kwa chilengedwe ndi kutentha, chinyezi, kugwedezeka, ndi mphamvu zotsutsana ndi kusokoneza.
Zofunikira za servo drive ya injini:
1. Galimotoyo imatha kuyenda bwino kuchokera ku liwiro lotsika kwambiri kupita ku liwiro lapamwamba kwambiri, ndipo kusinthasintha kwa torque kuyenera kukhala kocheperako, makamaka pa liwiro lotsika monga 0.1r / min kapena kutsika, pamakhala liwiro lokhazikika popanda kukwawa.
2. Galimotoyo iyenera kukhala ndi mphamvu zambiri zolemetsa kwa nthawi yaitali kuti zikwaniritse zofunikira za liwiro lotsika komanso torque yapamwamba.Nthawi zambiri, ma servo motors a DC amayenera kuchulukitsidwa ka 4 mpaka 6 mkati mwa mphindi zochepa popanda kuwonongeka.
3. Kuti akwaniritse zofunikira pakuyankhidwa mwachangu, injiniyo iyenera kukhala ndi kamphindi kakang'ono ka inertia ndi torque yayikulu, ndikukhala ndi nthawi yaying'ono yokhazikika komanso yoyambira magetsi momwe zingathere.
4. Galimoto iyenera kupirira kuyambika pafupipafupi, mabuleki ndi kuzungulira mozungulira.
