izindaba

Ukukhetha injini ye-micro DC kungase kubonakale kulula, kodwa ukukhetha okungalungile kungaholela ekusebenzeni kabi, umsindo omkhulu, noma ukwehluleka kusenesikhathi. Njengomkhiqizi, sibona amakhasimende amaningi ehlupheka ngemingcele eyisisekelo. Nasi umhlahlandlela wesinyathelo ngesinyathelo ukukusiza wenze ukukhetha okufanele.

1. Chaza imikhawulo yakho ye-voltage kanye neyamanje

Iningi lama-motor e-micro DC lisebenza ku-3V, 6V, 12V, noma 24V. I-voltage ephezulu ivame ukusho ukuthi i-current ephansi yamandla afanayo, kodwa ukunikezwa kwamandla kwesistimu yakho kanye ne-driver IC kuzonquma ububanzi obusebenzayo. Hlola njalo i-no‑load kanye ne-stall current – ​​zithinta impilo yebhethri kanye nokushabalaliswa kokushisa.

2. Qondanisa isivinini kanye ne-torque nomthwalo wakho

Isivinini (RPM) kanye ne-torque (g·cm noma mNm) yizinto ezimbili ezibaluleke kakhulu eziphumayo. Iphutha elivamile ukugxila kuphela esivinini. Isibonelo, ifeni encane idinga isivinini esiphezulu kodwa i-torque ephansi, kuyilapho ukhiye oqhutshwa yigiya udinga i-torque ephezulu ngesivinini esiphansi. Sebenzisa ijika lesivinini se-torque yemoto (elitholakala kushidi ledatha) ukuthola indawo yokusebenza. Uma i-torque yakho yomthwalo idlula i-torque elinganiselwe yemoto, imoto ingase ime noma ishise kakhulu.

3. Nquma phakathi kokubhulashwa kanye nokungabhulashwa

Ama-motor e-DC axutshwe kahle ayabiza futhi kulula ukuwalawula nge-PWM elula. Alungele ukusetshenziswa ngezikhathi ezithile noma ngezindleko eziphansi njengamathoyizi, amaphampu, nama-actuator. Ama-motor e-DC angenamabhulashi (BLDC) anikeza ukusebenza kahle okuphezulu, ukuphila isikhathi eside, nomsindo kagesi ophansi, kodwa adinga isilawuli se-elekthronikhi. Khetha i-BLDC ukuze isebenze njalo (isb., amafeni, amadivayisi ezokwelapha, amarobhothi).

4. Cabanga ngosayizi kanye nokufakwa

Ifektri yethu ikhiqiza ama-motor kusukela ku-6mm kuya ku-60mm ububanzi. Linganisa isikhala esitholakalayo ekuhlanganisweni kwakho - ungakhohlwa ubude bomgodi kanye nokuqondiswa kwesixhumi. Izimbobo noma amabakaki ajwayelekile okufakwa angenziwa ngokwezifiso, kodwa ukusebenzisa amathuluzi ngokwezifiso kwengeza izindleko nesikhathi sokuhola.

5. Hlola izidingo zemvelo nezokuphila konke

Izinga lokushisa lokusebenza, umswakama, uthuli, kanye nokudlidliza konke kuthinta impilo yemoto. Ngezinhlelo zokusebenza zangaphandle noma zezimoto, bheka izilinganiso ze-IP (isb., i-IP54). Ngemikhiqizo ehlala isikhathi eside (ngaphezu kwamahora ayi-1000), cabanga ngamabhulashi ensimbi ayigugu noma imiklamo engenamabhulashi. Cela imibiko yokuhlolwa kokuphila kithi.

Icebiso lokugcina: hlola njalo ngomthwalo wakho wangempela. Amashidi edatha ayisiqalo, kodwa ukusebenza kwangempela kungahluka. Cela amasampula bese usebenzisa ukuqinisekisa kwakho. Injini ekhethwe kahle yonga izindleko, isikhathi, kanye nezinkinga zewaranti.
