Musiyano wepesvedzero yemuchina wecnc pakati peServo motors uye Step motors?

Zvisinei3d atc cnc router muchina, CO2 laser yekucheka muchinakanaSS CS laser yekucheka muchinaetc. Motor ndechimwe chezvinhu zvinokosha uye zvinokosha zvinoriumba.Motokari uye mutyairi zvakare ndiwo4 × 8 ft cnc routerkufamba hurongwa.Iyo mota uye mutyairi chinhu chakakosha pakuita kwekushanda uye kushanda nemazvo kwemuchina.Especial yekushanda nemazvo.Kunewo zvimwe zvakawanda zvakakosha zvinokanganisa kurongeka kwemuchina.Asi pakupedzisira, inowanikwa nekudzora kufamba kwemota uye kugamuchirwa kwechiratidzo.

 

Kune mhando mbiri dzemotor: Servo mota uye nhanho mota.Munyika, kune vazhinji vanogadzira servo mota uye vazhinji vanogadzira mota nhanho.Tekai anongo sarudza iyo inozivikanwa pasi rese brand.Kune iyo servo mota, tinogara tichisarudza France Shield, Japanese Yaskawa, Taiwan Delta uye Syntec etc. Nhanho mota tinoshandisa Leadshine, 34MA, 450B kana 450C.Ndeupi mutsauko wenhanho mota uye servo mota?

 

Kuita kwakasiyana kwemitambo: Kana mafambiro ekutanga emota yekutsika akanyanya kana mutoro wakakurisa, zviri nyore kurasikirwa nematanho kana kumira.Kana kumhanya kwakanyanya, zviri nyore kukonzera overshoot.Nokudaro, kuitira kuti ive nechokwadi chekutonga kwayo, dambudziko rekukurumidza uye pasi rinofanira kubatwa zvakanaka.

 

Iyo AC servo drive system yakavharwa-loop control, dhiraivha inogona kuenzanisa zvakananga chiratidzo chemhinduro yemota encoder, uye yemukati chinzvimbo loop uye yekumhanyisa loop inoumbwa.Kazhinji, chiitiko chekurasikirwa kwenhanho kana kuwedzeredza kwemota yekutsika hazvizoitika, uye kuita kwekutonga kunonyanya kuvimbika.

 

Zvakanakira servo motors pamusoro stepper motors ndeaya anotevera

 

Nyaradzo: Kupisa uye ruzha zvakaderedzwa zvakanyanya.

 

Kumhanyisa: kuita kwakanaka kwepamusoro-kumhanya, kazhinji kumhanyisa kumhanya kunogona kusvika 20003000 rpm;

 

Kurongeka: yakavharwa-loop kutonga kwechinzvimbo, kumhanya uye torque kunoitwa;dambudziko re stepper motor kunze-kwe-danho rinokundwa;

 

Nguva: Iyo inoshanduka nguva yekupindura yekumhanyisa mota uye kudzika ipfupi, kazhinji mukati memakumi emamilliseconds;

 

Yakagadzika: Iyo yakaderera-kumhanya oparesheni yakagadzikana, uye nhanho oparesheni chiitiko chakafanana neinotsika mota haizoitike kana yakaderera-kumhanya oparesheni inoitwa.Inoshanda kune zviitiko zvine high-speed mhinduro zvinodiwa;

 

Adaptability: Yakasimba yekurwisa-kuwandisa kugona, inokwanisa kumira mitoro katatu iyo yakatemerwa torque, kunyanya yakakodzera kune dzimwe nguva nekuchinjika kwepakarepo uye nekukurumidza kutanga-up zvinodiwa;

 

Servo injini

 

Servo yakavharwa-loop control, stepper yakavhurika-loop control, uyu ndiwo mutsauko wakanyanya.Kunyanya, iyo servo mota yakavharwa-loop control (inopedzwa nemhinduro encoder, nezvimwewo), ndiko kuti, kumhanya kwemota kuchayerwa munguva chaiyo;iyo stepper mota yakavhurika-loop control, inoisa pulse, iyo inotsika mota inotendeuka yakagadziriswa kona, asi Velocity haina kuyerwa.

 

Iyo yekutanga torque ye servo mota yakakura kwazvo, ndiko kuti, kutanga kunokurumidza.Iyo yakayerwa kumhanya inogona kusvikwa munguva pfupi kwazvo.Inokodzera kugara uchitanga nekumira uye pane chinodiwa chekutanga torque.Panguva imwecheteyo, simba re servo mota rinogona kunge rakakura kwazvo, uye rinoshandiswa zvakanyanya mukugadzira.Kutanga kweiyo stepper mota kunonoka, uye inofanirwa kuenda kuburikidza neiyo frequency maitiro kubva pasi kusvika kumusoro.Stepper motors kazhinji haina kuwandisa kugona, nepo servo mota dzakaremerwa zvakanyanya.

 

Iyo parameter yenhanho mota yatinoshandisa:
