Ikhono lokulawula ijubane lemoto ye-DC liyisici esibalulekile. Ivumela ukulungiswa kwejubane lemoto ukuze kuhlangatshezwane nezidingo ezithile zokusebenza, okuvumela kokubili ukukhuphuka nokuncipha kwesivinini. Kulo mongo, sinemininingwane yezindlela ezine zokunciphisa ngempumelelo isivinini semoto ye-DC.
Ukuqonda ukusebenza kwemoto ye-DC kuveza4 izimiso ezibalulekile:
1. Ijubane lemoto lilawulwa isilawuli sejubane.
2. Ijubane lemoto lilingana ngqo ne-voltage yokuhlinzeka.
3. Isivinini se-motor siphambene ngokuphambene nokwehla kwe-voltage ye-armature.
4. Ijubane lemoto lilingana ngokuphambene nokuguquguquka njengoba kuthonywe okutholwe yinkambu.
Ijubane lemoto ye-DC lingalawulwa4 izindlela eziyinhloko:
1. Ngokufaka isilawuli se-DC motor
2. Ngokushintsha i-voltage yokuhlinzeka
3. Ngokulungisa i-voltage ye-armature, nangokushintsha ukumelana nezikhali
4. Ngokulawula ukugeleza, nangokulawula umsinga ngokusebenzisa amajika enkundla
Bheka leziIzindlela ezi-4 zokushintsha isivininiyemoto yakho ye-DC:
1. Ukufaka isilawuli sesivinini se-DC
U-gearbox, ongawuzwa futhi ubizwa ngokuthi i-gear reducer noma i-speed reducer, inqwaba yamagiya ongawengeza enjini yakho ukuze uyibambezele futhi/noma uyinike amandla engeziwe. Ukuthi yehlisa ijubane kangakanani kuncike esilinganisweni segiya kanye nendlela ugearbox osebenza kahle ngayo, okuwuhlobo olufana nesilawuli se-DC motor.
Ungafinyelela kanjani ukulawulwa kwemoto ye-DC?
Sinbadamadrayivu, afakwe isilawuli sejubane esididiyelwe, avumelanisa izinzuzo zamamotho e-DC anezinhlelo zokulawula zikagesi eziyinkimbinkimbi. Imingcele yesilawuli kanye nemodi yokusebenza ingalungiswa kahle kusetshenziswa isiphathi sokunyakaza. Kuye ngesivinini esidingekayo, indawo ye-rotor ingalandelelwa ngedijithali noma ngezinzwa ze-analog Hall ezitholakala ngokuzithandela. Lokhu kunika amandla ukulungiselelwa kwezilungiselelo zokulawula isivinini ngokuhambisana nomphathi wokunyakaza nama-adaptha ohlelo. Kumamotho kagesi amancane, izilawuli ezahlukahlukene ze-DC motor ziyatholakala emakethe, ezingalungisa isivinini semoto ngokuya ngokunikezwa kwamandla kagesi. Lokhu kufaka phakathi amamodeli afana ne-12V DC motor speed controller, 24V DC motor speed controller, kanye ne-6V DC motor speed controller.
2. Ukulawula isivinini nge-Voltage
Amamotho kagesi ahlanganisa i-spectrum ehlukahlukene, kusukela kumamodeli wamandla amahhashi amancane afanele izinto zikagesi ezincane ukuya kumayunithi anamandla amakhulu anezinkulungwane zamandla amahhashi okusebenza kwemboni esindayo. Isivinini sokusebenza semoto kagesi sithonywa ukwakheka kwayo kanye nemvamisa ye-voltage esetshenzisiwe. Uma umthwalo ubanjwa njalo, isivinini semoto silingana ngokuqondile ne-voltage yokuhlinzeka. Ngenxa yalokho, ukuncipha kwe-voltage kuzoholela ekwehleni kwejubane lemoto. Onjiniyela bakagesi banquma isivinini semoto esifanele ngokusekelwe ezidingweni ezithile zohlelo ngalunye, okufana nokucacisa amandla ehhashi maqondana nomthwalo wemishini.
3. Ukulawula isivinini nge-Armature Voltage
Le ndlela iqondene ngqo namamotho amancane. I-winding field ithola amandla emthonjeni ongaguquki, kuyilapho i-armature winding inikwa amandla umthombo ohlukile, oguquguqukayo we-DC. Ngokulawula i-voltage ye-armature, ungalungisa isivinini semoto ngokushintsha ukumelana ne-armature, okuthinta ukwehla kwe-voltage kuyo yonke i-armature. I-resistor eguquguqukayo isetshenziswa ochungechungeni nge-armature yale njongo. Lapho i-resistor eguquguqukayo isendaweni ephansi kakhulu, ukumelana ne-armature kuyinto evamile, futhi i-voltage ye-armature iyancipha. Njengoba ukumelana kukhula, i-voltage ngaphesheya kwe-armature iyehla ngokuqhubekayo, yehlisa isivinini se-motor futhi igcina isivinini sayo ngaphansi kwezinga elivamile. Kodwa-ke, i-drawback enkulu yale ndlela ukulahlekelwa kwamandla okuphawulekayo okubangelwa i-resistor ochungechungeni lwe-armature.
4. Ukulawula isivinini nge-Flux
Le ndlela ilungisa ukugeleza kazibuthe okukhiqizwa ama-windings ensimu ukuze ilawule isivinini senjini. I-flux kazibuthe incike kumanje odlula endaweni ejikajikayo, engashintshwa ngokulungisa i-current. Lokhu kulungiswa kufezwa ngokuhlanganisa i-resistor eguquguqukayo ochungechungeni ne-resistor emazombezombe yasensimini. Ekuqaleni, nge-resistor eguquguqukayo esimisweni saso esincane, umthamo wamanje olinganiselwe ugeleza endaweni ejikajikayo ngenxa ye-voltage yokuhlinzeka elinganiselwe, ngaleyo ndlela igcine isivinini. Njengoba ukumelana kuncipha kancane kancane, i-current ngokusebenzisa i-field winding iyaqina, okuholela ekuguquguqukeni okungeziwe kanye nokwehliswa okulandelayo kwejubane lemoto ngaphansi kwenani layo elijwayelekile. Nakuba le ndlela iphumelela ekulawuleni isivinini semoto ye-DC, ingaba nomthelela enqubweni yokushintshashintsha.
Isiphetho
Izindlela esizibhekile ziyidlanzana lezindlela zokulawula isivinini semoto ye-DC. Ngokucabanga ngawo, kucace bha ukuthi ukwengeza u-gearbox omncane ukuze usebenze njengesilawuli semoto nokukhetha injini enamandla kagesi aphelele kuwumnyakazo ohlakaniphe ngempela futhi ovumelana nesabelomali.
