A servo (servomechanism) chishandiso chemagetsi chinoshandura magetsi kuita chaiwo anodzorwa kufamba nekushandisa maitiro asina kunaka emhinduro.
Servos inogona kushandiswa kugadzira mutsara kana denderedzwa kufamba, zvichienderana nerudzi rwavo. Kugadzirwa kweyakajairika servo kunosanganisira mota yeDC, chitima chegiya, potentiometer, dunhu rakasanganiswa (IC) uye shaft yekubuda. Iyo inodiwa servo chinzvimbo ndeyekuisa uye inouya sechiratidzo chekodhi kuIC. Iyo IC inotungamira mota kuti iende, ichityaira simba remota kuburikidza nemagiya anoseta kumhanya uye inodiwa nzira yekufamba kudzamara chiratidzo chinobva ku potentiometer chapa mhinduro yekuti chishuwo chasvika uye IC inomisa mota.
Iyo potentiometer inoita inodzorwa kufamba kugoneke nekudzoreredza chinzvimbo chiripo ichibvumira kururamiswa kubva kune ekunze mauto anoshanda pane ekudzora nzvimbo: Kana iyo nzvimbo yafambiswa iyo potentiometer inopa chiratidzo chenzvimbo uye iyo IC inosaina inodiwa mota kufamba kusvika iyo chaiyo chinzvimbo yadzoserwa.
Musanganiswa we servos uye akawanda-geared emagetsi mota anogona kurongeka pamwe chete kuti aite mamwe mabasa akaomarara mumhando dzakasiyana dzemasisitimu anosanganisira marobhoti, mota, kugadzira uye isina waya sensor uye actuator network.
Ko servo inoshanda sei?
Servos ane waya nhatu dzinowedzera kubva mubhokisi (Ona mufananidzo kuruboshwe).
Imwe neimwe yewaya idzi inoshanda chimwe chinangwa. Idzi waya nhatu ndedzekutonga, simba, uye pasi.
Iyo tambo yekudzora ine basa rekupa mapurusi emagetsi. Iyo mota inotendeukira kune kwakakodzera kutungamira sekurairwa nemapulses.
Kana mota ichitenderera, inoshandura kupikisa kwe potentiometer uye pakupedzisira inobvumira dunhu rekutonga kuti ridzore huwandu hwekufamba uye kutungamira. Kana shaft iri panzvimbo yaunoda, simba rekupa rinovhara.
Iyo tambo yemagetsi inopa servo nesimba rinodiwa kushanda, uye tambo yepasi inopa nzira yekubatanidza yakaparadzana kubva kune huru ikozvino. Izvi zvinokutadzisa kuvhunduka asi hazvidiwi kumhanya servo.
Digital RC Servos Inotsanangurwa
Digital ServoA Digital RC Servo ine imwe nzira yekutumira masaini ekurova kune servo mota.
Kana iyo analogi servo yakagadzirirwa kutumira nguva dzose 50 pulse voltage pasekondi, iyo digital RC servo inokwanisa kutumira kusvika ku300 pulses pasekondi!
Nezviratidziro izvi zvinokurumidza kuputika, kumhanya kwemota kuchawedzera zvakanyanya, uye torque ichave yakawedzera; inoderedza kuwanda kwekufa.
Nekuda kweizvozvo, kana servo yedhijitari ichishandiswa, inopa mhinduro nekukurumidza uye nekukurumidza kukurumidza kuchikamu cheRC.
Zvakare, neine shoma bhendi, iyo torque inopawo zvirinani kubata. Paunenge uchishanda uchishandisa dijitari servo, unogona kuona iko iko kunzwa kwekutonga.
Rega ndikupe nyaya yechiitiko. Ngatiti iwe unofanirwa kubatanidza dhijitari uye analog servo kune anogamuchira.
Paunoshandura analog servo vhiri kubva-pakati, iwe unozoona kuti inopindura uye inopikisa mushure mechinguva - kunonoka kunoonekwa.
Nekudaro, kana iwe ukatenderedza vhiri redhijitari servo kubva-pakati, iwe unonzwa sekunge vhiri uye shaft inopindura uye inobata kune chinzvimbo chaunoisa nekukurumidza uye zvakanaka.
Analog RC Servos Inotsanangurwa
Analog RC servo mota ndiyo yakajairwa mhando ye servo.
Inogadzirisa kumhanya kwemota nekungotumira nekudzima pulses.
Kazhinji, iyo pulse voltage iri pakati pe4.8 kusvika 6.0 volts uye inogara iripo panguva iyoyo. Iyo analogi inogamuchira makumi mashanu pulses kwesekondi yega yega uye kana yazorora, hapana voltage inotumirwa kwairi.
Iyo yakareba iyo "On" pulse iri kutumirwa kune servo, iyo inokurumidza iyo mota inotenderera uye yakakwirira iyo inogadzirwa torque. Chimwe chezvipingamupinyi zvikuru zveanalog servo kunonoka kwayo kuita kune mirairo midiki.
Iyo haitore mota ichitenderera nekukurumidza zvakakwana. Uyezve, inogadzirawo simbe torque. Iyi mamiriro anonzi "deadband".
