servo e sebetsa joang?
Li-Servos li na le lithapo tse tharo tse tlohang ka har'a casing (Sheba setšoantšo ka ho le letšehali).
E 'ngoe le e 'ngoe ea lithapo tsena e sebeletsa morero o itseng.Lithapo tsena tse tharo ke tsa taolo, matla le fatše.
Mohala oa taolo o ikarabella bakeng sa ho fana ka maqhubu a motlakase.Enjene e fetohela ka tsela e nepahetseng joalo ka ha e laeloa ke maqhubu.
Ha motlakase o potoloha, o fetola ho hanyetsa ha potentiometer mme qetellong o lumella potoloho ea taolo ho laola palo ea motsamao le tataiso.Ha shaft e le sebakeng se lakatsehang, matla a phepelo a tima.

Digital RC Servos Hlalosa
Digital ServoA Digital RC Servo e na le mokhoa o fapaneng oa ho romela mats'oao a ho otla ha motlakase ho servo motor.
Haeba servo ea analog e etselitsoe ho romela motlakase oa 50 ka motsotsoana, digital RC servo e khona ho romela ho fihla ho 300 pulse ka motsotsoana!
Ka lipontšo tsena tse potlakileng tsa pulse, lebelo la motlakase le tla eketseha haholo, 'me torque e tla ba e tsitsitseng haholoanyane;e fokotsa kotsi ea ho ruruha.
Ka lebaka leo, ha servo ea digital e sebelisoa, e fana ka karabo e potlakileng le ho potlakisa ka potlako ho karolo ea RC.
Hape, ka li-deadband tse fokolang, torque e boetse e fana ka bokhoni bo betere ba ho tšoara.Ha o sebetsa o sebelisa servo ea dijithale, o ka utloa maikutlo a taolo hanghang.
E re ke u fe boemo ba nyeoe.Ha re re u lokela ho hokahanya servo ea dijithale le analog ho moamoheli.
Ha u tlosa lebili la servo la analog ho tloha bohareng, u tla hlokomela hore e arabela le ho hanyetsa ka mor'a nakoana - ho lieha hoa bonahala.
Leha ho le joalo, ha u reteletsa lebili la servo ea dijithale ho tloha bohareng, u tla ikutloa eka lebili le shaft lia arabela 'me li tšoarella sebakeng seo u se behileng kapele le hantle.
Analog RC Servos E Hlalositsoe
Analog RC servo motor ke mofuta o tloaelehileng oa servo.
E laola lebelo la enjene ka ho romela feela le ho tima pulse.
Ka tloaelo, motlakase oa pulse o pakeng tsa 4.8 ho isa ho 6.0 volts 'me o lula o le teng.Analoge e amohela li-pulses tse 50 motsotsoana o mong le o mong mme ha e phomotse, ha ho na motlakase o romelloang ho eona.
Ha nako e telele ea "On" e ntse e romelloa ho servo, lebelo la motlakase le ntse le phahama le torque e hlahisoang.E 'ngoe ea litšitiso tse kholo tsa servo ea analog ke ho lieha ha eona ho arabela litaelong tse nyane.
Ha e etse hore enjene e bilike kapele ho lekana.Ho feta moo, e boetse e hlahisa torque e botsoa.Boemo bona bo bitsoa "deadband".
