Impembelelo yomahluko kumatshini we-cnc phakathi kweenjini ze-Servo kunye neenjini zeNyathelo?

Noba kutheniUmatshini we-3d atc cnc router, Umatshini wokusika we-CO2 laserokanyeUmatshini wokusika we-laser we-SS CSnjl. IMotor yenye yezona zinto zisisiseko kwaye zibalulekileyo.Iimoto kunye nomqhubi nazo4×8 ft cnc umzilainkqubo ehambayo.Injini kunye nomqhubi yinto ebalulekileyo yokusebenza komsebenzi kunye nokuchaneka kokusebenza komatshini.Ingakumbi ngokuchaneka kokusebenza.Kukho nezinye izinto ezininzi ezibalulekileyo ezichaphazela ukuchaneka komatshini.Kodwa ekugqibeleni, iqondwa ngokulawula ukuhamba kwemoto kunye nokwamkelwa komqondiso.

 

Kukho iintlobo ezimbini zeenjini: i-Servo motor kunye ne-motor step.Ehlabathini, baninzi abavelisi beemoto ze-servo kunye nabavelisi abaninzi beemoto.I-Tekai ikhetha kuphela i-brand eyaziwayo yehlabathi.Kwimoto ye-servo, sihlala sikhetha i-France Shield, i-Yaskawa yaseJapan, i-Taiwan Delta kunye ne-Syntec njl njl. Inyathelo lemoto sisebenzisa i-Leadshine, i-34MA, i-450B okanye i-450C.Yintoni umahluko wemoto yenyathelo kunye ne-servo motor?

 

Ukusebenza kwezemidlalo okwahlukileyo: Ukuba isantya sokuqala semoto yokunyathela siphezulu kakhulu okanye umthwalo mkhulu kakhulu, kulula ukuphulukana namanyathelo okanye isitali.Xa isantya siphezulu kakhulu, kulula ukwenza i-overshoot.Ngoko ke, ukwenzela ukuba kuqinisekiswe ukuchaneka kokulawula kwayo, ingxaki yesantya kunye nokuhla kufuneka iphathwe kakuhle.

 

Inkqubo ye-AC servo drive ivaliwe-loop control, i-drive inokwenza isampuli ngokuthe ngqo umqondiso wengxelo ye-encoder yemoto, kwaye i-loop yendawo yangaphakathi kunye ne-loop yesantya yenziwa.Ngokubanzi, isenzeko sokulahleka kwenyathelo okanye ukudutyulwa kwemoto yokunyathela akuyi kwenzeka, kwaye ukusebenza kolawulo kunokwethenjelwa ngakumbi.

 

Iingenelo zeenjini ze-servo ngaphezulu kweenjini ze-stepper zezi zilandelayo

 

Intuthuzelo: Ubushushu kunye nengxolo ziyancipha kakhulu.

 

Isantya: ukusebenza kakuhle kwesantya esiphezulu, isantya esilinganiselwe ngokubanzi sinokufikelela kwi-20003000 rpm;

 

Ukuchaneka: ulawulo oluvaliweyo lwesikhundla, isantya kunye ne-torque yenzeka;ingxaki ye-stepper motor ngaphandle kwenyathelo iyoyiswa;

 

Ixesha: Ixesha lokuphendula eliguquguqukayo lokunyuka kwemoto kunye nokunciphisa lifutshane, ngokubanzi phakathi kwamashumi e-millisecond;

 

Izinzile: Umsebenzi wesantya esiphantsi uzinzile, kwaye isiganeko sokunyathela esifana ne-motor steping asiyi kwenzeka xa kwenziwa umsebenzi ophantsi.Isebenza kwiimeko ezineemfuno zokuphendula ngesantya esiphezulu;

 

Ukulungelelaniswa: Ikhono elinamandla lokuchasana nokugqithiswa, likwazi ukumelana nemithwalo ngokuphindwe kathathu i-torque elinganisiweyo, ngokukodwa ifanelekile kwiimeko ezinokuguquguquka kwemithwalo yangoko kunye neemfuno zokuqalisa ngokukhawuleza;

 

Servo motor

 

I-Servo lulawulo oluvaliweyo, i-stepper lulawulo oluvulekileyo, lo ngowona mahluko usisiseko.Ngokukodwa, i-servo motor ivaliwe-loop control (igqitywe ngempendulo ye-encoder, njl.), Oko kukuthi, isantya semoto siya kulinganiswa ngexesha langempela;I-stepper motor ilawula i-loop evulekileyo, igalelo i-pulse, i-stepper motor iya kujika i-angle esisigxina, kodwa i-Velocity ayilinganiswa.

 

I-torque yokuqala ye-servo motor inkulu kakhulu, oko kukuthi, ukuqala ngokukhawuleza.Isantya esilinganiselweyo sinokufikelelwa ngexesha elifutshane kakhulu.Kufanelekile ukuqalisa rhoqo kunye nokuyeka kwaye kukho imfuneko yokuqalisa i-torque.Ngelo xesha, amandla e-servo motor anokuba mkhulu kakhulu, kwaye asetyenziswa ngokubanzi kwimveliso.Ukuqaliswa kwe-motor ye-stepper kucotha, kwaye kufuneka kudlule inkqubo yokuphindaphinda ukusuka ezantsi ukuya phezulu.Iimotor zeStepper azinasakhono sokugcwala, ngelixa iimotor ze-servo zigcwele kakhulu.

 

Iparameter yenyathelo lemoto esiyisebenzisayo:
