Injini chinhu chakakosha kwazvo pamagetsiPurinda ye3D, kururama kwayo kwakabatana nemhedzisiro yakanaka kana yakaipa yekudhinda kwe3D, kazhinji kudhinda kwe3D pakushandiswa kwemota yestepper.
Saka pane maprinta e3D anoshandisa mamota eservo here? Anoshamisa uye akarurama, asi sei asingaashandise pamaprinta e3D akajairwa?
Dambudziko rimwe chete: inodhura zvakanyanya! Kana ichienzaniswa nemaprinta e3D akajairwa hazvina kukodzera. Kana iri nani kune maprinta eindasitiri, inogona kuvandudza kururama kwayo zvishoma.
Pano tichatora injini mbiri idzi, ongororo yakadzama yekuenzanisa kuti tione musiyano uripo.
Tsanangudzo dzakasiyana.
Mota yesteppermudziyo wekufamba wakasiyana, wakasiyana neAC yakajairika uyeMota dzeDC, mota dzakajairika dzinoenda kumagetsi kuti dzitenderedzwe, asi mota yekutsika haisi, mota yekutsika inofanira kugamuchira murairo wekuita nhanho.
Servo motor ndiyo injini inodzora mashandiro ezvikamu zvemakanika muservo system, izvo zvinogona kuita kuti kumhanya kwekudzora, kururama kwenzvimbo zvive kwakarurama kwazvo, uye zvinogona kushandura chiratidzo chevoltage kuita torque nekumhanya kuti chityaire chinhu chekudzora.
Kunyangwe zviviri izvi zvakafanana mu control mode (pulse string uye directional signal), pane musiyano mukuru mukushandiswa kwe performance uye application occasions. Iye zvino kuenzanisa kushandiswa kwe performance mbiri idzi.
Kururama kwekudzora kwakasiyana.
Mapoinzi mavirimota yemhando yepamusoro ye hybrid stepperkona yedanho inowanzo kuve , 1.8 °, 0.9 °
Kururama kwekudzora kwemota yeAC servo kunovimbiswa nerotary encoder iri kumashure kwemota shaft. Kune mota yePanasonic fully digital AC servo, semuenzaniso, kune mota ine standard 2500-line encoder, pulse equivalent ndeye 360°/10000=0.036° nekuda kwetekinoroji ye quadruple frequency inoshandiswa mukati me drive.
Kune mota ine 17-bit encoder, dhiraivha inogamuchira 217=131072 pulses per motor revolution, zvinoreva kuti pulse yakaenzana nayo i360°/131072=9.89 seconds, inova 1/655 yepulse yakaenzana neye stepper motor ine step angle ye1.8°.
Hunhu hwakasiyana-siyana hwemafrequency akaderera.
Mota yestepper ine kumhanya kwakaderera ichaonekwa sechiitiko chekudedera kwakaderera. Kudedera kwacho kwakabatana nemamiriro emutoro uye mashandiro edhiraivha, uye inowanzoonekwa sehafu yefrequency yekutanga isina mutoro yemota.
Chiitiko ichi chekudengenyeka kwemafrequency mashoma chinotsanangurwa nepfungwa yekushanda kwemota yestepper chinokanganisa mashandiro emuchina. Kana mota dzestepper dzichishanda nekumhanya kwakaderera, tekinoroji yekudengenyeka inofanira kushandiswa kukunda chiitiko chekudengenyeka kwemafrequency mashoma, senge kuwedzera ma dampers kumota, kana kushandisa tekinoroji yekuparadzanisa padhiraivha.
Mota yeAC servo inomhanya zvakanaka uye haizunguzike kunyangwe pakumhanya kwakaderera. Sisitimu yeAC servo ine basa rekudzora resonance, rinogona kuvhara kusasimba kwemuchina, uye sisitimu ine basa rekugadzirisa mafrequency mukati, rinogona kuona nzvimbo yeresonance yemuchina uye kuita kuti sisitimu igadziriswe.
Mashandiro akasiyana ekushanda.
Kudzora mota dzeStepper kunodzora mota dzakavhurika, kana paine frequency yekutanga yakakwira zvakanyanya kana kuti yakakura zvakanyanya, mutoro unowanzo konzera nhanho dzakarasika kana kuvharika, kana paine kumhanya kwakanyanya kana kumira kuchigona kupfura zvakanyanya, saka kuti ive nechokwadi chekuti kudzora kwayo kwakarurama, inofanira kugadzirisa dambudziko rekumhanya nekukwira nekudzika.
AC servo drive system yekutonga kwe closed-loop, mutyairi anogona kuratidza zvakananga chiratidzo chemhinduro ye encoder yemota, chimiro chemukati che loop uye speed loop, kazhinji hachizoonekwi stepper motor kurasikirwa ne stepper kana overshoot, uye mashandiro ekutonga akavimbika.
Muchidimbu, sisitimu yeAC servo muzvikamu zvakawanda zvekushanda kwayo iri nani pane mota yestepper. Asi mune dzimwe nguva isinganyanyi kuoma inoshandisawo mota yestepper kuita mota. Printer ye3D haisi yakaoma zvakanyanya, uye mota yeservo inodhura zvakanyanya, saka ndiyo inonyanya kusarudzwa mota yestepper.
