1, He aha nā ʻano o nā mīkini stepper miniature? He aha ko lākou mau ʻano?
Ua māhele ʻia i ʻekolu mau māhele e pili ana i ke ʻano o ka rotor. ʻO ke ʻano PM (ʻano magnet mau) he ʻano maʻalahi, ke kumukūʻai haʻahaʻa loa, a me kahi kihi ʻanuʻu o 7.5 ° a i ʻole 15 °. He torque liʻiliʻi kona a kūpono no nā noi e like me nā mea paʻi a me nā gimbals kāmela ʻaʻole pono ka pololei kiʻekiʻe; Hana ʻia nā rotors ʻano VR (variable reluctance) i nā mea magnetic palupalu me ka hoʻonā haʻahaʻa (ma kahi o ka hapalua o ke ʻano HB) a me nā ʻano transient maikaʻi ʻole, a i kēia manawa ʻaʻole i hoʻohana pinepine ʻia; Hoʻohui ka ʻano HB (hybrid) i nā pono o nā mea mua ʻelua, me kahi kihi ʻanuʻu maʻamau o 1.8 ° a i ʻole 0.9 °, torque kiʻekiʻe, a me ka hoʻonā kiʻekiʻe, e lilo ia i koho nui no nā lako micro precision.
2, He aha ka pololei o ke kihi ʻanuʻu o kahi mīkini stepper liʻiliʻi? E hōʻiliʻili anei nā hewa?
ʻO ka pololei o kahi motika stepper maʻamau he 3% a 5% o ke kihi ʻanuʻu a ʻaʻole ia e hōʻiliʻili. ʻO ke ʻano kēia, ʻoiai ma hope o nā pōʻaiapuni hana he nui, ʻaʻole e hōʻiliʻili nā hewa o kēlā me kēia ʻanuʻu i ke kūlana hope loa. ʻO ka pololei maʻamau o kahi motika stepper micro hybrid ʻelua-pae hiki ke hōʻea i ka 0.18 ° (no kahi kihi ʻanuʻu o 1.8 °).
3, Pehea ka nui o ka torque e hiki ai i kahi mīkini stepper miniature ke hoʻopuka?
He nui loa ka laulā o ka ʻike. ʻO ka torque paʻa no nā nui o ke kumu mīkini ma lalo o 20mm o ke ʻano PM he 0.02N · m wale nō; ʻO ka NEMA 8~NEMA 11 (20mm~28mm) maʻamau mai 0.03~0.1N · m; Hiki i ka NEMA 14~NEMA 17 (35mm~42mm) ke hiki i ka 0.2~0.5N · m. ʻOi aku ma mua o 0.8N · m maʻamau e pono ai kahi kumu NEMA 17 a ʻoi aku paha, kahi e ʻoi aku ma mua o ka māhele "micro".
4, No ke aha e emi ai ka torque o kahi motika stepper i ka piʻi ʻana o ka wikiwiki?
I ka wā e wili ana, hoʻopuka ka inductance wili i kahi ikaika electromotive hoʻohuli, a ʻo ke kiʻekiʻe o ke alapine (frequency), ʻoi aku ka nui o ka ikaika electromotive hoʻohuli, e hopena ana i ka emi ʻana o ke au o ka pae a me ka torque hoʻopuka. He emi nā wili wili o nā micro motors a he haʻahaʻa ka inductance, kahi e ʻoi aku ai ka ʻike ʻia o kēia hopena i nā wikiwiki kiʻekiʻe.
5, Hiki ke hoʻohana ʻia nā mīkini stepper micro no ka neʻe linear?
ʻAe. Hoʻohui ka motika stepper linear i ka wili i loko o ka rotor a hoʻopuka pololei i ka neʻe linear, e kāpae ana i ka pono no nā mīkini hoʻoili waho. ʻO ka hahau o nā motika stepper micro linear maʻamau ma waena o 10mm ~ 200mm, me ka pahu o 0.5N ~ 10N. Hoʻohana pinepine ʻia lākou i nā pamu infusion, nā pamu infusion, a me nā mea hana ʻokiʻoki micro.
6, He aha nā palena i hoʻoholo mua ʻia i ke koho ʻana i kahi motika micro stepper?
ʻO ka mea mua, e hoʻoholo i ka torque ukana a me ka wahi hoʻonohonoho. Pono ka torque paʻa e ʻoi aku ma mua o 1.3 mau manawa o ka torque ukana maoli. Ke noʻonoʻo nei he ʻano koʻikoʻi loa nā micro motors i ka overload, ua ʻōlelo ʻia e lawe i kahi kumu palekana o 1.4 a 2 mau manawa. I ka manawa like e hōʻoia ai i ka wahi hoʻonohonoho i loaʻa, ʻo ka nui pinepine ka palena mua i nā micro devices.
7, He aha ka ʻokoʻa ma waena o ka mālama ʻana i ka torque a me ka torque dynamic?
ʻO ka mālama ʻana i ka torque ka torque kiʻekiʻe loa e hiki ai i kahi motika ke mālama me ke au i helu ʻia ke kūpaʻa, e hōʻike ana i kona hiki static. ʻO ka torque dynamic ka torque output maoli i ka wā o ka hana, kahi e hilinaʻi ʻia ana i ke au awelika i ka wā o ka hana a emi iho me ka piʻi ʻana o ka wikiwiki. I ke koho ʻana, ʻaʻole hiki iā mākou ke kālele wale i ka mālama ʻana i ka torque, pono mākou e kuhikuhi i ke piʻo ʻano alapine torque.
8, Pehea e koho ai i ka nui o ke kumu e pili ana i ka torque?
Kuhikuhi ʻike: Hiki ke koho ʻia ʻo NEMA 8~NEMA 17 ma lalo o 0.8N · m; Ma lalo o 0.1N · m, ua lawa ka NEMA 8~NEMA 11. I nā hiʻohiʻona noi micro, ʻo ke koi torque maʻamau i loko o 0.5N · m, me NEMA 14~NEMA 17 ka pae nui.
9, Pehea e hoʻomaopopo ai i ke au i helu ʻia o kahi motika stepper miniature?
ʻO ke au hoʻokele (au pae) ka waiwai kuhikuhi o ke au ma nā wēlau ʻelua o kahi wili pae hoʻokahi, ʻaʻole ia he palena paʻa. Hiki ke hoʻoponopono ʻia a puni ka waiwai i helu ʻia e like me nā kūlana hana maoli, akā ʻo ka ʻoi aku ma mua o ka waiwai i helu ʻia e hoʻonui i ka hoʻomehana ʻana, a ma lalo o ka waiwai i helu ʻia e hopena i ka lawa ʻole o ka torque. He kiʻekiʻe loa ke kū'ē ʻana o ka wili o nā micro motors, a ʻo ke au hoʻokele maʻamau ma ka pae o 0.2 ~ 1.5A.
10, He mea nui anei ka hoʻohālikelike inertia i ke koho ʻana i nā mīkini stepper micro?
He mea nui loa. ʻOi aku ka kiʻekiʻe o ka lakio o ka inertia ukana i ka inertia rotor motika, hiki ke alakaʻi i ka pane dynamic maikaʻi ʻole a me ka nalowale maʻalahi o nā ʻanuʻu i ka wā e hoʻolalelale ai. He liʻiliʻi loa ka inertia o ka rotor o kahi micro motor ponoʻī, akā ʻoi aku ka nui o ka inertia ma ka ʻaoʻao ukana (e like me ka wili a me ka hoʻopili ʻana) ma mua o ka motika ponoʻī, no laila pono e helu ʻia i ke koho ʻana.
