Ka'idar aiki na servo motor

A servo motorMota ce mai iya sarrafa matsayi, gudu, da hanzari kuma yawanci ana amfani dashi a aikace-aikacen da ke buƙatar ingantaccen sarrafa motsi. Ana iya fahimta a matsayin motar da ke bin umarnin siginar sarrafawa: kafin a ba da siginar sarrafawa, rotor yana tsaye; Lokacin da aka aika siginar sarrafawa, rotor yana juyawa nan da nan; Lokacin da siginar sarrafawa ya ɓace, rotor na iya tsayawa nan da nan. Ƙa'idar aiki ta ƙunshi tsarin sarrafawa, encoder da madauki na amsawa. Mai zuwa shine cikakken bayani na yadda servo Motors ke aiki:

Tsarin sarrafawa: Tsarin sarrafawa na servo motor yawanci ya ƙunshi mai sarrafawa, direba da mota. Mai sarrafawa yana karɓar sigina na sarrafawa daga waje, kamar umarnin matsayi ko umarnin gudu, sannan ya canza waɗannan sigina zuwa sigina na yanzu ko ƙarfin lantarki kuma ya aika su zuwa ga direba. Direba yana sarrafa jujjuyawar motar bisa ga siginar sarrafawa don cimma matsayin da ake buƙata ko sarrafa saurin gudu.

Encoder: Motoci na Servo galibi ana sanye su da abin rufe fuska don auna ainihin matsayi na rotor. Encoder yana mayar da bayanin matsayi na rotor zuwa tsarin sarrafawa don tsarin sarrafawa zai iya saka idanu akan matsayin motar a ainihin lokacin kuma daidaita shi.

Madogarar ra'ayi: Tsarin sarrafawa na servo Motors yawanci yana ɗaukar kulawar rufaffiyar madauki, wanda ke daidaita fitar da injin ta ci gaba da auna ainihin matsayi da kwatanta shi da matsayin da ake so. Wannan madauki na amsa yana tabbatar da cewa matsayin motar, saurin gudu, da haɓakawa sun yi daidai da siginar sarrafawa, yana ba da ikon sarrafa motsi daidai.

Algorithm na sarrafawa: Tsarin sarrafawa na servo motor yawanci yana ɗaukar PID (daidaitacce-haɗin-haɗin-haɓaka) algorithm sarrafawa, wanda ke ci gaba da daidaita fitowar motar don sanya ainihin matsayi kusa da matsayin da ake so. Algorithm na sarrafa PID na iya daidaita fitowar motar bisa ga bambanci tsakanin ainihin matsayi da matsayin da ake so don cimma daidaitaccen sarrafa matsayi.

A cikin aiki na ainihi, lokacin da tsarin sarrafawa ya karbi matsayi ko umarni na sauri, direba zai sarrafa jujjuyawar motar bisa ga waɗannan umarnin. A lokaci guda, mai rikodin rikodin yana ci gaba da auna ainihin matsayi na rotor na motar kuma yana ciyar da wannan bayanin zuwa tsarin sarrafawa. Tsarin sarrafawa zai daidaita fitowar motar ta hanyar sarrafa PID algorithm bisa ga ainihin bayanin matsayi da aka mayar da shi ta hanyar mai ɓoyewa, ta yadda ainihin matsayi ya kasance kusa da yadda ake so.

Za'a iya fahimtar ka'idar aiki na motar servo a matsayin tsarin kula da madauki mai rufewa wanda ke ci gaba da auna ainihin matsayi kuma yana kwatanta shi tare da matsayin da ake so, kuma yana daidaita kayan aikin motar bisa ga bambanci don cimma daidaitattun matsayi, saurin gudu da hanzari. Wannan ya sa servo Motors yadu amfani da aikace-aikace bukatar high-madaidaicin motsi iko, kamar CNC inji kayan aikin, mutummutumi, aiki da kai kayan aiki da sauran filayen.
