ʻO ka hopena ʻokoʻa no ka mīkini cnc ma waena o nā kaʻa Servo a me nā kaʻa Step?

2022-09-05

He mea ʻole3d atc cnc mīkini alahele, CO2 mīkini ʻoki lasera i ʻoleSS CS mīkini ʻoki laseretc. ʻO ka motika kekahi o nā mea nui a koʻikoʻi.ʻO ke kaʻa a me ke kalaiwa pū kekahi4×8 ft cnc routerʻōnaehana neʻe.ʻO ka mīkini a me ka mea hoʻokele ka mea koʻikoʻi no ka hana hana a me ka pololei o ka hana ʻana o ka mīkini.Nui no ka pololei o ka hana.Nui nā mea nui ʻē aʻe e pili ana i ka pololei o ka mīkini.Akā i ka hopena, ʻike ʻia ma ka hoʻomalu ʻana i ka neʻe ʻana o ka kaʻa a me ka loaʻa ʻana o ka hōʻailona.

 

ʻElua mau ʻano kaʻa: Servo motor a me step motor.I ka honua, nui nā mea hana kaʻa servo a me nā mea hana kaʻa kaʻa he nui.Koho wale ʻo Tekai i ka brand kaulana honua.No ka motika servo, koho mau mākou iā France Shield, Japanese Yaskawa, Taiwan Delta a me Syntec etc. Step motor hoʻohana mākou i Leadshine, 34MA, 450B a i ʻole 450C.He aha ka ʻokoʻa o ke kaʻa kaʻa a me ka ʻenekini servo?

 

ʻO nā hana haʻuki like ʻole: Inā kiʻekiʻe ke alapine o ka hoʻomaka ʻana o ke kaʻa kaʻa wāwae a i ʻole ka nui o ka ukana, maʻalahi ka nalo ʻana i nā ʻanuʻu a i ʻole ke kūpaʻa.Ke kiʻekiʻe loa ka wikiwiki, maʻalahi ke kumu o ka overshoot.No laila, i mea e hōʻoiaʻiʻo ai i ka pololei o ka mana, pono e mālama maikaʻi ʻia ka pilikia o ka wikiwiki a me lalo.

 

ʻO ka ʻōnaehana hoʻokele AC servo he kaohi-loop control, hiki i ka drive ke hōʻike pololei i ka hōʻailona manaʻo o ka encoder motor, a ua hoʻokumu ʻia ka loop position internal a me ka loop loop speed.ʻO ka maʻamau, ʻaʻole e kū mai ke ʻano o ka nalo ʻana a i ʻole overshoot o ke kaʻa wāwae, a ʻoi aku ka hilinaʻi o ka hana hoʻomalu.

 

ʻO nā mea maikaʻi o nā motika servo ma luna o nā kaʻa stepper penei

 

Hōʻoluʻolu: Hoʻemi nui ʻia ka wela a me ka walaʻau.

 

ʻO ka wikiwiki: maikaʻi ka wikiwiki wikiwiki, hiki i ka wikiwiki i helu ʻia i ka 20003000 rpm;

 

ʻO ka pololei: ʻike ʻia ka mana o ke kūlana, ka wikiwiki a me ka torque;ka pilikia o ka stepper motor out-of-step ua lanakila;

 

Manawa: He pōkole ka manawa pane ikaika o ka holo kaʻa a me ka deceleration, ma ke ʻano he ʻumi milliseconds;

 

Paʻa: Paʻa ka hana haʻahaʻa haʻahaʻa, a ʻaʻole hiki ke hana ʻia ke ʻano hana e like me ke kaʻa wāwae ke hana ʻia ka hana haʻahaʻa haʻahaʻa.Hoʻopili i nā manawa me nā koi pane kiʻekiʻe;

 

Hiki ke hoʻololi: ʻO ka mana anti-overload ikaika, hiki ke kū i nā ukana ʻekolu mau manawa o ka torque i helu ʻia, kūpono loa no nā manawa me ka loli koke a me nā koi hoʻomaka wikiwiki;

 

Servo motor

 

ʻO Servo ka mana pani pani, ʻo ka stepper ka mana open-loop, ʻo ia ka ʻokoʻa maʻamau.ʻO ka mea kikoʻī, ua pani ʻia ke kaʻa servo (hoʻopau ʻia e ka manaʻo encoder, etc.), ʻo ia hoʻi, e ana ʻia ka wikiwiki o ke kaʻa i ka manawa maoli;ʻO ke kaʻa stepper he mana wehe-loop, hoʻokomo i kahi pulse, e hoʻohuli ke kaʻa stepper i kahi kihi paʻa, akā ʻaʻole ana ʻia ka Velocity.

 

ʻO ka torque hoʻomaka o ka mīkini servo he nui loa, ʻo ia hoʻi, wikiwiki ka hoʻomaka.Hiki ke loaʻa ka wikiwiki i helu ʻia i ka manawa pōkole loa.He kūpono ia no ka hoʻomaka pinepine a me ka hoʻomaha ʻana a aia kahi koi torque hoʻomaka.I ka manawa like, hiki ke nui loa ka mana o ka mīkini servo, a hoʻohana nui ʻia i ka hana.He lohi ka hoʻomaka ʻana o ke kaʻa stepper, a pono ia e hele i ke kaʻina o ka alapine mai ka haʻahaʻa a kiʻekiʻe.ʻAʻole i loaʻa i nā kaʻa stepper ka mana overload, aʻo nā kaʻa servo i ka nui loa.

 

ʻO ka ʻāpana o ke kaʻa kaʻa a mākou e hoʻohana ai:
