ʻOkoʻa ʻokoʻa ʻana i ka Motor Stepping Motor a me Servo Motor

Tʻo ia ka mana o nā ʻano like ʻole

ʻO ka motika wāwae (he kihi o ka pulse, ka mana open-loop): ua hoʻololi ʻia ka hōʻailona pulse uila i ka neʻe ʻana i ka angular a i ʻole ka neʻe ʻana o ka laina o ka mana open-loop, inā ʻaʻole overload, ka wikiwiki o ke kaʻa, ke kūlana o ka hoʻomaha wale nō e hilinaʻi i ka pinepine o ka pulse a me ka helu o nā pulses, me ka ʻole o ka hoʻololi ʻana o ka ukana.

Hoʻokaʻawale ʻia nā kaʻa stepper e like me ka helu o nā pae, a ua hoʻohana nui ʻia nā kaʻa stepper ʻelua a me ʻelima mau ʻāpana i ka mākeke. Hiki ke hoʻokaʻawale ʻia ke kaʻa kaʻa wāwae ʻelua i 400 mau ʻāpana like no ka hoʻololi ʻana, a hiki ke hoʻokaʻawale ʻia ka pae ʻelima i 1000 mau ʻāpana like, no laila ʻoi aku ka maikaʻi o nā hiʻohiʻona o ka pae ʻelima pae, ʻoi aku ka pōkole a me ka manawa deceleration, a haʻahaʻa haʻahaʻa inertia. ʻO ka ʻanuʻu ʻanuʻu o ʻelua-phase hybrid stepping motor ma ke ʻano he 3.6 °, 1.8 °, a ʻo ka ʻanuʻu ʻanuʻu o ka ʻelima mau ʻāpana hybrid stepping motor ma ke ʻano he 0.72 °, 0.36 °.

Servo motor (he kihi o nā pulupulu he nui, pani-loop control): ʻo ka servo motor kekahi ma o ka mana o ka helu o nā pulses, servo motor rotation angle, e hoʻouna aku i ka helu kūpono o nā pulses, aʻo ka mea hoʻokele e loaʻa i ka hōʻailona manaʻo hoʻi, a ʻo ka mīkini servo e hana i ka hoʻohālikelike ʻana i nā pulses, i ʻike ka ʻōnaehana i ka helu o nā pulses, a me ka manawa e hiki ai ke hoʻihoʻi ʻia ka pulse i ka manawa like. pololei loa ka hoohuli ana o ke kaa. Hoʻoholo ʻia ka pololei o ka mīkini servo e ka pololei o ka encoder (helu o nā laina), ʻo ia hoʻi, ʻo ka servo motor ponoʻī ka hana o ka hoʻouna ʻana i nā pulses, a hoʻouna ʻo ia i ka helu like o nā pulses no kēlā me kēia kihi o ka rotation, i mea e hana ai ka servo drive a me ka servo motor encoder pulses i leo, no laila, he mana kaʻa a pani ʻia.

Lʻokoʻa nā ʻano ow-frequency

Ke kaʻa kaʻa: hiki ke maʻalahi ka haʻalulu haʻahaʻa i nā wikiwiki haʻahaʻa. Ke holo haʻahaʻa ke kaʻa wāwae wāwae, pono e hoʻohana i ka ʻenehana damping e lanakila ai i ke ʻano haʻahaʻa haʻahaʻa haʻahaʻa, e like me ka hoʻohui ʻana i kahi damper ma ke kaʻa, a i ʻole ke kalaiwa me ka ʻenehana subdivision.

Servo motor: ʻoluʻolu loa ka hana ʻana, ʻoiai me ka haʻahaʻa haʻahaʻa ʻaʻole e ʻike ʻia kahi hanana haʻalulu.

TʻO nā ʻano manawa-frequency o nā ʻano like ʻole

ʻO ke kaʻa kaʻa: ke emi nei ka torque hoʻopuka me ka piʻi ʻana o ka wikiwiki, a hoʻemi ʻo ia i nā wikiwiki kiʻekiʻe, no laila ʻo 300-600r / min ka wikiwiki o kāna hana.

Servo motor: ka hoʻokuʻu torque mau, ʻo ia hoʻi, i kona wikiwiki helu (maʻamau 2000 a i ʻole 3000 r / min), ka puka i helu ʻia i ka torque, i ka wikiwiki helu ma luna o ka mana mau.

Dʻokoʻa overload kaha

ʻAʻole hiki ke hoʻonui i ka mana. ʻO ke kaʻa kaʻa no ka mea ʻaʻohe mana o ka overload, i mea e lanakila ai i ke koho ʻana i kēia manawa o ka inertia, pono pinepine e koho i kahi torque nui o ka kaʻa, a ʻaʻole pono ka mīkini i ka nui o ka torque i ka wā o ka hana maʻamau.

Nā mīkini servo: loaʻa i ka mana overload ikaika. Loaʻa iā ia ka wikiwiki overload a me ka torque overload hiki. ʻO kona kiʻekiʻe kiʻekiʻe he ʻekolu manawa o ka torque i helu ʻia, hiki ke hoʻohana ʻia e lanakila ai i ka manawa o ka inertia o nā ukana inertial i ka manawa hoʻomaka o ka inertia.

Dʻokoʻa ka hana hana

ʻO ke kaʻa kaʻa: ka hoʻokele kaʻa kaʻa no ka mana open-loop, ʻoi aku ka kiʻekiʻe o ka hoʻomaka ʻana a i ʻole ka nui o ka haʻahaʻa e nalowale i nā ʻanuʻu a i ʻole ke kāohi ʻana i ke ʻano o ka hoʻokuʻu ʻana i ke kiʻekiʻe kiʻekiʻe ka wikiwiki i ke ʻano o ka overshooting, no laila i mea e hōʻoia ai i ka pololei o kāna kaohi, pono e mālama ʻia me ka pilikia o ka piʻi ʻana a me ka hāʻule ʻana o ka wikiwiki.

Servo motor: AC servo drive system for closed-loop control, the driver can be straight on the motor encoder feedback signal sampling, the internal composition of the position loop and speed loop, maʻamau ʻaʻole ʻike ʻia i ka neʻe ʻana o ka kaʻa kaʻa o nā ʻanuʻu a i ʻole ke ʻano o ka overshooting, ʻoi aku ka hilinaʻi o ka hana mana.

Sʻokoʻa ka hana pane peed

ʻO ke kaʻa kaʻa: e hoʻolalelale mai ke kū ʻana a hiki i ka wikiwiki o ka hana (ma ka maʻamau he mau haneli hoʻololi i kēlā me kēia minuke) pono 200 ~ 400ms.

Servo kaʻa: AC servo nenoaiu acceleration hana i oi aku, mai standstill accelerate i kona helu wikiwiki o 3000 r / min, he mau milliseconds wale nō, hiki ke hoʻohana ʻia no nā koi o ka hoʻomaka wikiwiki a me ka pono o ka positional pono o ka mana o ke kula kiʻekiʻe.
