1. Menene motar servo?
Servo Motors, wanda kuma aka sani da actuator motors, su ne masu kunnawa a cikin tsarin sarrafawa waɗanda ke canza siginar lantarki zuwa kusurwoyi ko gudu akan shaft don fitar da abin sarrafawa.Motar Servo, wanda kuma aka sani da motar zartarwa, wani yanki ne na zartarwa a cikin tsarin sarrafawa ta atomatik wanda ke canza siginar wutar lantarki da aka karɓa zuwa matsuguni na kusurwa ko fitowar saurin kusurwa a kan mashin motar.
An kasu kashi DC da AC servo Motors.Babban fasalinsa shine lokacin da siginar siginar ta zama sifili, babu wani yanayi na juyawa, kuma saurin yana raguwa daidai da karuwar karfin.
2. Matsakaicin halaye na servo motor
Lokacin da akwai shigarwar siginar sarrafawa, motar servo tana juyawa;idan babu shigar da siginar sarrafawa, zai daina juyawa.Ana iya canza saurin gudu da shugabanci na motar servo ta hanyar canza girma da lokaci (ko polarity) na ƙarfin sarrafawa.Tun daga shekarun 1980s, tare da haɓaka haɗaɗɗun da'irori, fasahar lantarki da fasahar sarrafa saurin AC, fasahar tuƙi ta AC servo na dindindin ta sami ci gaba sosai.Shahararrun masana’antun kera motoci a kasashe daban-daban sun kaddamar da nasu jerin na’urorin sarrafa motoci na AC servo da servo, kuma suna ci gaba da ingantawa da sabunta su.
Tsarin AC servo ya zama babban jagorar ci gaba na tsarin servo mai girma na zamani, wanda ke sa tsarin servo na asali na DC ya fuskanci rikicin kawar da shi.Bayan 1990s, tsarin AC servo na kasuwanci a duk duniya ana sarrafa su ta hanyar injunan kalaman sine da ke sarrafa cikakken lambobi.Ci gaban AC servo drives a fagen watsawa yana canzawa tare da kowace rana wucewa.
3. Idan aka kwatanta da na yau da kullum Motors, servo Motors suna da wadannan halaye
(1) Matsakaicin tsarin saurin yana da faɗi.Yayin da ƙarfin wutar lantarki ya canza, saurin motar servo na iya ci gaba da daidaitawa a kan kewayo mai fadi.
(2) Rotor inertia karami ne, don haka zai iya farawa da tsayawa da sauri.
(3) Ƙarfin sarrafawa yana da ƙananan, ƙarfin nauyin nauyi yana da ƙarfi, kuma amincin yana da kyau.
4. Aikace-aikacen yau da kullun na motar servo a cikin tsarin sarrafawa ta atomatik

Menene ka'idodin aiki na servo Motors?A taƙaice, tsarin AC servo ya fi na injinan stepper ta hanyoyi da yawa.Koyaya, a wasu yanayi masu ƙarancin buƙata, ana amfani da injinan stepper azaman injin kunnawa.Sabili da haka, a cikin tsarin ƙira na tsarin kulawa, wajibi ne a yi la'akari da mahimmancin bukatun kulawa, farashi da sauran dalilai don zaɓar motar sarrafawa mai dacewa.
