Servo mota ikufanana ndi stepper mota momwe amagwirira ntchito ndi kapangidwe kake, koma magwiridwe antchito a servo mota ndi osiyana kwambiri. Kodi pali kusiyana kotani? Kodi pali kusiyana kotani pakati pa servo mota ndi sitepe yamagalimoto pakugwiritsa ntchito zida zamakina mwatsatanetsatane?
Choyamba, mawonekedwe otsika pafupipafupi a servo motor ndi stepper motor ndiosiyana.
Stepper mota sachedwa kugwedezeka kotsika pafupipafupi. Njira yogwiritsira ntchito sitepe yamagalimoto imatsimikiza kuti chodabwitsa chafupipafupi chakuzunguliridwa ndichosavomerezeka pakugwiritsa ntchito makina. Oyendetsa masitepe ambiri amangowerengera momwe angayendere kuti asinthe momwe angayang'anire mayendedwe awo.
Ac servo mota imayenda bwino kwambiri, ngakhale kuthamanga kwambiri sikuwoneka ngati kugwedezeka. Ac servo system imagwira ntchito yopondereza ma resonance, yomwe imatha kupanga kusowa kwa makina, ndipo imakhala ndi ma analytic function (FFT) mkati mwa makina, omwe amatha kuzindikira mawonekedwe amakanidwe ndikuthandizira kusintha kwamachitidwe.
Chachiwiri, magwiridwe antchito a servo motor ndi stepper ndi osiyana.
Kuwongolera kwamagalimoto opita ndikutseguka kotseguka, ma frequency oyambira ndi okwera kwambiri kapena katundu ndi wokulirapo, ndipo chodabwitsa cha kupitirira kapena kuwombera kosavuta kumawoneka kothamanga kwambiri, kotero kuti muwonetsetse kulondola kwake, mavuto akuchulukirachulukira akuyenera kuthetsedwa bwino. Dongosolo loyendetsa la AC servo latsekedwa. Woyendetsa akhoza kutengera mwachindunji chizindikiro cha mayankho a mota encoder. Mpheteyo ndi mphete yothamanga zimapangidwa mkati. Nthawi zambiri, palibe kuchepa kwa sitepe kapena kupitilira kwa mota wopondapo, ndipo magwiridwe antchito ndi odalirika kwambiri.
Chachitatu, mawonekedwe afupipafupi a servo motor ndi stepper motor ndiosiyana.
Linanena bungwe makokedwe a stepper galimoto amachepetsa ndi kuwonjezeka kwa liwiro, ndipo udzachepa zikuchepa pa liwiro apamwamba, kotero pazipita liwiro ntchito ya stepper galimoto zambiri 300 ~ 600 rpm .. The makokedwe linanena bungwe la stepper galimoto adzakhala ndichepe mwamphamvu liwiro lapamwamba AC servo mota imatulutsa ma torque nthawi zonse, ndiye kuti, mkati mwa kuthamanga kwake (makamaka 2000 RPM kapena 3000 RPM), imatha kutulutsa makokedwe ovomerezeka ndi mphamvu yamagetsi yopitilira liwiro loyerekeza.
Chachinayi, magwiridwe antchito a servo motor ndi stepper mota amayankha mosiyana.
Woyendetsa galimoto amatenga 200 ~ 400 milliseconds kuti afulumizitse kuchokera kupumula mpaka kuthamanga liwiro, nthawi zambiri mazana osintha pamphindi. Kuchita bwino kwa machitidwe a AC servo ndibwino. Kutenga Mingzhi 400 W AC servo mota monga chitsanzo, zimangotenga ma millisecond ochepa kuti muthamangitse kuchoka pa static kupita pa liwiro lake la 3000 RPM lomwe lingagwiritsidwe ntchito pakuwongolera komwe kumafuna kuyamba ndikuima mwachangu.
Nthawi zina zovuta kwambiri, ma servo motors okhala ndi magwiridwe antchito kwambiri kuposa ma stepper amayenera kugwiritsidwa ntchito. Ngakhale China ili ndi mafakitale athunthu padziko lonse lapansi, ambiri mwa iwo ali mgulu la "olimba mtima komanso omasuka", ndipo pakadali mpata waukulu pakudzikundikira kwa zinthu zapamwamba kwambiri.
Chachisanu, servo mota ndi stepper mota kulondola molondola ndizosiyana.
Gawo lamagawo oyenda osakanikirana awiriwa ndi 1.8,0.9, ndipo la magawo asanu ophatikizika ndi 0.72,0.36. Komabe, kulondola kwa kayendedwe ka AC servo mota kumatsimikizika ndi makina ozungulira kumapeto kwa shaft yamagalimoto. Kwa mota yokhala ndi encoder ya 17, the
