Nekuvandudzwa kwedhijitari yekudzora tekinoroji, mazhinji emafambiro ekudzora masisitimu anoshandisastepper motorskana servo motors semagetsi ekuuraya. Kunyangwe iwo maviri ari mukutonga modhi akafanana (pulse tambo uye chiratidzo chekutungamira), asi mukushandiswa kwekuita uye zviitiko zvekushandisa pane musiyano mukuru.
Kutsika mota&Servo mota
Tanodzora nzira dzakasiyana
Kutsika mota (kona ye pulse, yakavhurika-loop control): iyo yemagetsi pulse siginecha inoshandurwa kuita yeangular displacement kana mutsara kuchinjika kweyakavhurika-loop control, kana isiri-yakawandisa, kumhanya kwemota, chinzvimbo chekumira chinongoenderana nekuwanda kweiyo pulse chiratidzo uye huwandu hwemapurusi, pasina pesvedzero yekuchinja kwemutoro.
Stepper mota dzinonyanya kuiswa zvichienderana nehuwandu hwezvikamu, uye maviri-chikamu uye shanu-chikamu stepper motors anoshandiswa zvakanyanya mumusika. Iwo maviri-chikamu anotsika mota anogona kupatsanurwa kuita mazana mana akaenzana zvikamu pashanduko, uye shanu-chikamu chinogona kupatsanurwa kuita 1000 zvikamu zvakaenzana, saka hunhu hwechishanu-chikamu chinotsika mota zviri nani, kupfupika kumhanyisa uye kudzikisa nguva, uye kuderera kwesimba inertia. Nhanho yenhanho yeaviri-phase hybrid stepping mota inowanzo 3.6 °, 1.8 °, uye nhanho kona yeshanu-chikamu hybrid stepping mota inowanzo 0.72 °, 0.36 °.
Servo mota (kona yeakawanda pulses, yakavharwa-loop control): servo mota iri zvakare kuburikidza nekutonga kwehuwandu hwemapulses, servo mota inotenderera angle, inotumira iyo inoenderana nhamba yemapulses, nepo mutyairi achizogamuchirawo chiratidzo chemhinduro kumashure, uye servo mota kugadzira kuenzanisa kwemapurusi, kuitira kuti sisitimu izive huwandu hwemapurusi anotumirwa panguva imwe chete iyo ma pulses anotumirwa. kumashure, achakwanisa kudzora kutenderera kwemota nemazvo. Iko kurongeka kweiyo servo mota inotemerwa nekurongeka kweiyo encoder (nhamba yemitsara), kureva kuti, servo mota pachayo ine basa rekutumira mapurusi, uye inotumira iyo inoenderana nhamba yemapulses pamakona ese ekutenderera, kuitira kuti servo drive uye servo mota encoder pulses iite echo, yakavharwa-loop control iri, yakavhurika nhanho inodzora.
Low-frequency maitiro akasiyana
Kutsika mota: yakaderera-frequency vibration iri nyore kuitika nekumhanya kwakaderera. Kana mota inotsika ichishanda mukumhanya kwakaderera, kazhinji inofanirwa kushandisa tekinoroji yekunyorova kukunda iyo yakaderera-frequency vibration chiitiko, sekuwedzera damper pamota, kana kutyaira uchishandisa kupatsanura tekinoroji.
Servo mota: yakatsetseka kushanda, kunyangwe pakumhanya kwakaderera hakuzoratidzi vibration chiitiko.
Tiye nguva-frequency maitiro akasiyana
Kutsika mota: iyo torque inobuda inodzikira nekuwedzera kwekumhanya, uye inodzikira zvakanyanya pakumhanya kwakakwira, saka kumhanya kwayo kwakanyanya kushanda kunowanzo 300-600r/min.
Servo mota: inogara ichibuda torque, ndiko kuti, mukumhanya kwayo kwakayerwa (kazhinji 2000 kana 3000 r/min), iyo inobuda yakatemerwa torque, mukumhanya kwakayerwa pamusoro pesimba rinogara richibuda.
Dkusaita kuwandisa kwehuwandu
Kutsika mota: kazhinji haina kuwandisa. Kutsika mota nekuti hapana yakawandisa yakawandisa, kuti ukunde kusarudzwa kweino nguva ye inertia, zvinowanzodikanwa kusarudza yakakura torque yemota, uye muchina haudi torque yakawandisa panguva yekushanda kwakajairwa, pachave nekuraswa kwechiitiko che torque.
Servo motors: iva nesimba rakawandisa. Iyo ine yekumhanyisa overload uye torque overload kugona. Iyo yakakura torque yakapetwa katatu iyo yakayerwa torque, iyo inogona kushandiswa kukurira iyo inertia yeinertial mitoro panguva yekutanga-up inertia.
Dkusashanda kwekushanda
Kutsika mota: kutsika mota yekudzora yakavhurika-loop control, yekutanga frequency yakawandisa kana yakawandisa mutoro unotadza kurasikirwa nenhanho kana kuvharira chiitiko chekumira zvakanyanya kumhanya kunowanzoitika kune chiitiko che overshooting, saka kuitira kuti ive nechokwadi chekutonga kwayo, inofanirwa kugadziriswa nedambudziko rekusimuka nekudonha.
Servo mota: AC servo drive system yekuvharika-loop control, mutyairi anogona kuve akananga pane mota encoder mhinduro chiratidzo sampling, iyo yemukati kuumbwa kweiyo chinzvimbo loop uye kumhanya loop, kazhinji hairatidzike mukutsika mota kurasikirwa kwematanho kana chiitiko che overshooting, kuita kwekutonga kunovimbika zvakanyanya.
Speed response performance yakasiyana
Kutsika mota: mhanyisa kubva pakumira kuenda kune kumhanya kwekushanda (kazhinji mazana akati wandei ekuchinja paminiti) inoda 200 ~ 400ms.
Servo mota: AC servo system yekumhanyisa kuita iri nani, kubva yakamira ichimhanyisa kusvika kune yayo yakatarwa kumhanya kwe3000 r/min, mashoma millisecond chete, inogona kushandiswa kune zvinodiwa zvekukurumidza kutanga-kumira uye chinzvimbo chechokwadi zvinodiwa zvekutonga kwemunda wepamusoro.
