ʻO ka wehewehe kikoʻī o ke kumu hana, ka hoʻokaʻawale ʻana a me nā ʻano o nā kaʻa stepper

ʻOiai ʻo ke ʻano kaʻa kaʻa kaʻa kaʻa ma ka mākeke e hoʻohana nui ʻia i nā kaʻa Servo, akā i kekahi mau kūlana, ʻoi aku ka maikaʻi o nā kaʻa stepper ma mua o nā kaʻa servo, no laila pono i nā ʻenekini uila e hoʻomaopopo i nā kaʻa stepper, no laila. E kūkākūkā kēia ʻatikala i ka loina hana, ka hoʻokaʻawale ʻana a me nā ʻano o nā kaʻa stepper i nā kikoʻī.

ʻO ka mīkini stepper kahi ʻano o ka mīkini induction. ʻO kāna kumu hana, ʻo ia ka hoʻohana ʻana i ka uila uila e hoʻolālā i ka circuit DC e hāʻawi i ka mana ma ka kaʻana manawa. ʻO ke kaʻina hana multi-phase e hoʻomalu i kēia manawa. Ke hoʻohana nei i kēia manawa e hāʻawi i ka mana i ke kaʻa stepper, hiki ke hana maʻamau ke kaʻa stepper. ʻO ia ka mana hoʻokaʻawale manawa no ke kaʻa stepper.

ʻOiai ua hoʻohana nui ʻia nā kaʻa stepper, ʻaʻole like nā kaʻa stepper e like me nā mea maʻamauNā motika DC, aNā motika AChoʻohana maʻamau. Pono e hoʻohana ʻia e ka ʻōnaehana hoʻomalu i haku ʻia me ka hōʻailona puʻupuʻu apo lua, ka mana kaapuni, a me nā mea ʻē aʻe. Loaʻa ia i nā ʻike ʻoihana he nui e like me nā mīkini, nā ʻenekini, nā uila a me nā kamepiula.

Ma ke ʻano he actuator, ʻo stepper motor kekahi o nā huahana koʻikoʻi o ka mechatronics a hoʻohana nui ʻia i nā ʻōnaehana mana automation.Me ka hoʻomohala ʻana o ka microelectronics a me ka ʻenehana kamepiula, ke piʻi nei ka noi no nā kaʻa stepper i kēlā me kēia lā, a hoʻohana ʻia lākou i nā ʻano ʻano o ka ʻoihana aupuni.

ʻO nā motika stepping maʻamau i hoʻohana pinepine ʻia, ʻo ia nā motika stepping reactive (VR), nā motika stepping magnet mau loa (PM), nā motika stepping hybrid (HB), a me nā kaʻa wāwae wāwae hoʻokahi.

ʻO ka mīkini stepper magnet mau loa:

ʻO ka mīkini kuʻekuʻe paʻa mau loa he ʻelua-phase, liʻiliʻi ka torque a me ka leo, a ʻo ke kihi ʻanuʻu he 7.5 degere a i ʻole 15 degere; ʻo ka mīkini kuʻekuʻe magnet paʻa i ka torque puka nui.Maikaʻi ka hana dynamic, akā nui ka ʻanuʻu.

Nā motika stepper reactive:

ʻO ka motika stepping reactive he ʻekolu-phase, hiki ke hoʻokō i ka puka torque nui. He 1.5 degere ke kuʻekuʻe wāwae, akā nui loa ka walaʻau a me ka haʻalulu. ʻO ka hoʻokele magnetic rotor o ke kaʻa kaʻa reactive i hana ʻia me nā mea magnetic palupalu. Loaʻa nā wili kahua multi-phase e hoʻohana i ka hoʻololi i ka permeance e hana i ka torque.

He ʻano maʻalahi ke kaʻa kaʻa reactive, ke kumu kūʻai haʻahaʻa, ke kihi ʻanuʻu liʻiliʻi, akā maikaʻi ʻole ka hana ikaika.

Hybrid stepper motor:

Hoʻohui ka motika stepping Hybrid i nā mea maikaʻi o nā kaʻa hoʻoneʻe magnet reactive a mau loa. Loaʻa iā ia ke kihi ʻanuʻu liʻiliʻi, puka nui a me ka hana hoʻoikaika maikaʻi. ʻO ia ke kaʻa kaʻa pae kiʻekiʻe loa i kēia manawa. Ua kapa ʻia ʻo ia ka induction magnet mau loa. Hoʻokaʻawale ʻia ka mīkini sub-stepping i ʻelua-phase a me ʻelima-phase: ʻo ka ʻāpana ʻelua ʻanuʻu he 1.8 degere, a ʻo ka ʻelima mau pae ʻanuʻu he 0.72 degere. ʻO kēia ʻano kaʻa kaʻa kaʻa i hoʻohana nui ʻia.
