Hunhu hunowanzo taurirwa uye hunowanzo kunzi cliché, uye kunyangwe kana ichishandiswa sezwi, mainjiniya mazhinji anokanda zano kubva munzira asati aongorora mamiriro acho.Kambani yega yega inoda kushandisa izwi iri, asi vangani vanoda kurishandisa?Hunhu chimiro uye mararamiro.Hunhu huri nyore kutaura, asi munyaya iyi zvakare chimwe chinhu chinogona kutsanangurwa pamatanho ese ekugadzira.Hunhu, kutanga uye zvakanyanya, hunofanira kutorwa zvakanyanya kubva kumusoro zvichidzika.Zvigadzirwa zvemotokari zvine hunyanzvi zvinoda kutariswa: mhando, kuendesa, uye mutengo (mumamiriro ekugadzira), uye kana iwe ukatarisa pamutengo, unokwanisa kupa vatengi chigadzirwa chemhando yepamusoro pasina kuwanda-engineering.Izvi zvinoreva kuti pane mhinduro iri nyore iyo iri nyore kugadzira uye kuendesa.Zvese zvimedu zvinofanirwa kubatanidzwa uye mutengesi wemotokari anofanirwa kunzwisisa chinangwa uye chinangwa chedhizaini yemushandisi.
Vatengesi vemotikari yemukati yemhando yekudzora masisitimu vanowanzo shandisa nzira ye4.5 sigma, uye 6 sigma haisi nzira inogutsa kune izvo vatengi vanoona kubva kune zvigadzirwa zvavo.Kuburikidza chete nekudzora kwakasimba kwemhando vanogona kuve nechokwadi chekuti chigadzirwa chinodiwa, kwete nekuda kwekugadzira.Nehurongwa uhu mushandisi anowana "motor inogara uye yakavimbika inosangana nezvinodiwa pamusoro pehupenyu hwemota".Ichi chinangwa chinonyanya kukosha mukugadzirwa kwepamusoro-soro, uko mitsetse yese yegungano inogona kumira nyore nyore nekuda kwekukanganisa kwechigadzirwa.Kuve nechokwadi chemhando yekambani stepper motors, ivo vanotarisa munzvimbo nhatu dzakakosha, chikamu chemhando, dhizaini mhando uye mhando yekugadzira.
Kusarudzwa kwevatengesi kunoita basa rakakosha mukupona nekusimudzira indasitiri yekugadzira mota uye zano rekugadzira, uye chikamu chakakosha chekutonga cheni.Paunenge uchitarisa chikamu chemhando, maitiro ekugadzira anosanganisira akawanda madiki maassemblies: stators, rotors, shafts, bearings, end caps, windings, lead, connectors, nezvimwe.Zvakare, imwe neimwe sub-assembly inogona kukamurwa kuita sub-assemblies senge waya, insulation, housings uye zvisimbiso, connectors, etc. Hapana anoshamisika patinofunga kuti kunaka kwechikamu chimwe nechimwe chinhu, kubva pasi kusvika kumusoro, chimwe nechimwe Chidimbu chinofanira. zvose zvive zvemhando yepamusoro kuitira kuti chigadzirwa chekupedzisira chipfuure.
Kune mota, iyo dimensional kurongeka uye concentricity ye rotor, stator uye end caps inonyanya kukosha, kuwedzera nzira yekuyerera mhiri kwe stator uye rotor mazino uku uchideredza kusada.Nokuda kweizvi, mhepo yemhepo kana gap pakati pe rotor uye stator inofanira kuva shoma.Iyo idiki iyo gap yemhepo, idiki iyo chikamu machining kukanganisa nzvimbo.Izvi zvinonzwika zviri nyore kunzwisisa, asi kana chimwe kana zvese zvikamu zvisina kunyatso kudzika, zvichikonzera kusaenzana kwemhepo mikaha inokonzeresa kusawirirana kwekuita.Mumamiriro ezvinhu akaipisisa, kana kusangana kukaitika, motokari inova isina maturo.
Rotor inertia inokanganisa kushanda kwese kweiyo stepper mota.Yakaderera inertia rotors inogona kupindura nekukurumidza uye inopa vashandisi kumhanya kwepamusoro uye yakakwirira dynamic torque.Yakakodzera end cap dhizaini inovimbisa yakakura yemukati vhoriyamu yakaiswa mune yakakura rotor.Mapeji ekupedzisira ane mutoro wekugadzirisa kwakarurama kwe rotor.Misalignment inogona kukanganisa hukuru hwechigadzirwa chekupedzisira, uye rotor misalignment inogona kukonzera kusaenzana kwemhepo uye kukonzeresa kuita kwakashata.
Izvi zvisingaenderani concentricity inobhadharwa nekuwedzera ukuru hwemhepo gap pakati pe rotor uye stator, kuderedza mukana wekusangana kwavo.Izvi zvinoshanda chete pakubvisa zvikanganiso.Iyi nzira inotadzisa zvakanyanya kuita kwema stepper motors, uye iyo yakakura kusiyana pakati pezvikamu, zvakanyanya kusawirirana kuita kunenge kuri.Kunyangwe shanduko diki dzinogona kuve nemhedzisiro yakakura pane inertia, kuramba, inductance, dynamic torque kubuda uye resonance (kusingadiwe vibration).Dhizaini yerotor ndiyo kiyi yekuwedzera kushanda kwemota, iyo rotor inofanirwa kuratidza yakakwana magineti kumusoro ichisara seyakajeka sezvinobvira kuderedza inertia ye rotor.
Iyo stator inogona kurongedzwa maererano nechinangwa chekupedzisira chekugadzira: kurongeka kwepamusoro, kutsvedzerera kana kuburitsa kwakakwira torque, uye dhizaini yemapuranga inosarudza kuti yakawanda sei mhepo inoputika inogona kukwana pakati pematanda e stator.Zvakare, iyo nhamba yemapango anowanzo 8, 12 kana 16 inoenderana nekurongeka uye torque kubuda kwemota.Iyo shaft inofanirwa kuve yakasimba zvakakwana kuti ikwanise kumira yakadzokororwa torque mitoro uye axial masimba pasina deformation kana kushatisa nekufamba kwenguva.Saizvozvowo, mabhengi anofanirwa kuenderana nekuita uye tarisiro yehupenyu yechigadzirwa chekupedzisira.Sechikamu chinotaridza hupenyu hwemotokari, mabheya anowanzo sangana nekupfeka zvakanyanya.
Zvimwe zvakakosha zvikamu zvinosanganisira zvivharo zvekupedzisira, izvo zvinobata mabheji munzvimbo uye inovimbisa kurongeka kwakakodzera pakati pe stator uye rotor.Iwo mabearings pachawo anofanirwa kunge ari emhando yepamusoro kuchengetedza uye kuona hupenyu hurefu hweiyo stepper mota.Danda rega rega rine magineti emagetsi, izvo zvinoda kutenderedzwa kwepango rega rega uchishandisa waya yepamusoro yegiredhi iripo.Kusiyana kwedhayamita yewaya kunogona kukonzera per-pole winding consistency nyaya, izvo zvinozokonzeresa kushomeka kwe torque, kuwedzera resonance kana vibration, uye kusagadziriswa zvakanaka muchigadzirwa chekupedzisira.
