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 angular displacement kana mutsara wekusimuka weiyo yakavhurika-loop control, kana isiri-yakawandisa, kumhanya kwemota, chinzvimbo che iyo inomira inongoenderana nehuwandu hwechiratidzo chepulse uye nhamba yemapulisi, pasina simba rekuchinja kwemutoro.
Stepper mota dzinonyanya kuiswa zvichienderana nehuwandu hwezvikamu, uye maviri-chikamu uye shanu-chikamu stepper motors anoshandiswa zvakanyanya mumusika. Iwo maviri-phase steping mota anogona kukamurwa kuita mazana mana akaenzana zvikamu parevolution, uye shanu-chikamu chinogona kupatsanurwa kuita 1000 zvikamu zvakaenzana, saka hunhu hwechishanu-chikamu chinotsika mota zviri nani, kupfupika kumhanyisa uye kudzikisa nguva, uye kuderera. dynamic 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 mhinduro. chiratidzo kumashure, uye servo mota kuti iite kuenzanisa kwemapuru, kuitira kuti sisitimu izive huwandu hwemapurusi anotumirwa kune servo mota, uye panguva imwechete mangani mapurusi akagamuchirwa kumashure, achakwanisa kudzora kutenderera kwe. injini yacho zvakanyatsonaka. Iko kunyatsojeka kweiyo servo mota inotemerwa nekurongeka kweiyo encoder (nhamba yemitsara), kureva kuti, iyo servo mota pachayo ine basa rekutumira pulses, uye inotumira iyo inoenderana nhamba yemapulses pamakona ese e. kutenderera, kuitira kuti servo drive uye servo mota encoder pulses iite echo, saka inovharika-loop control, uye inotsika mota ndeye yakavhurika-loop control.
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 kweiyi nguva ye inertia, zvinowanzodikanwa kusarudza yakakura torque yemota, uye muchina haudi torque yakawandisa panguva yekushanda kwakajairika, pachava. kuve kutambisa torque chiitiko.
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 yakakwira zvakanyanya kana yakawandisa mutoro unokwanisa kurasikirwa nenhanho kana kuvharira chiitiko chekumira zvakanyanya kumhanya kunowanzoitika kune chiitiko che overshooting, saka kuitira kuti uve nechokwadi. kurongeka kwekutonga kwayo, kunofanirwa kubatwa nedambudziko rekusimuka nekudonha nekukurumidza.
Servo mota: AC servo drive system yekuvhara-loop control, mutyairi anogona kunge 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, iyo control performance inonyanya kuvimbika.
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 irinani, kubva yakamira ichimhanyisa kusvika kune yayo yakatemerwa kumhanya ye3000 r/min, mashoma millisecond chete, inogona kushandiswa kune zvinodiwa zvekukurumidza kutanga-kumira uye chinzvimbo chechokwadi zvinodiwa zvekutonga kwepamusoro. munda.
