iindaba

Ukukhetha i-micro DC motor kunokubonakala kulula, kodwa ukukhetha okungalunganga kunokukhokelela ekusebenzeni kakubi, ingxolo egqithisileyo, okanye ukungaphumeleli kwangoko. Njengomvelisi, sibona abathengi abaninzi besokola ngemilinganiselo esisiseko. Nantsi isikhokelo senyathelo ngenyathelo ukukunceda wenze ukhetho olufanelekileyo.

1. Chaza i-voltage yakho kunye nemida yangoku

Uninzi lwee-motor ze-micro DC zisebenzisa i-3V, 6V, 12V, okanye i-24V. I-voltage ephezulu idla ngokuthetha ukuba kukho umbane ophantsi kumandla afanayo, kodwa umbane wenkqubo yakho kunye ne-IC yomqhubi ziya kugqiba uluhlu olusebenzayo. Soloko ujonga umbane ongathwaliyo kunye nowe-stall - zichaphazela ubomi bebhetri kunye nokuchithwa kobushushu.

2. Thelekisa isantya kunye ne-torque nomthwalo wakho

Isantya (RPM) kunye ne-torque (g·cm okanye mNm) zezona zinto zimbini zibalulekileyo. Impazamo eqhelekileyo kukugxila kwisantya kuphela. Umzekelo, ifeni encinci idinga isantya esiphezulu kodwa i-torque ephantsi, ngelixa isitshixo esiqhutywa yigiya sifuna i-torque ephezulu kwisantya esiphantsi. Sebenzisa i-torque yesantya semoto (efumaneka kwiphepha ledatha) ukuze ufumane indawo yokusebenza. Ukuba i-torque yakho yomthwalo idlula i-torque elinganisiweyo yemoto, imoto inokuma okanye ifudumale kakhulu.

3. Khetha phakathi kokubrashwa nokungabrashwa

Iimoto ze-DC ezibrashiweyo zibiza kancinci kwaye kulula ukuzilawula nge-PWM elula. Zilungele ukusetyenziswa rhoqo okanye ngexabiso eliphantsi njengeethoyi, iipompo, kunye nee-actuator. Iimoto ze-DC (BLDC) ezingenabhrashi zibonelela ngokusebenza okuphezulu, ubomi obude, kunye nengxolo ephantsi yombane, kodwa zifuna isilawuli se-elektroniki. Khetha i-BLDC ukuze isebenze rhoqo (umz., iifeni, izixhobo zonyango, iirobhothi).

4. Cinga ngobukhulu kunye nokufakelwa

Umzi-mveliso wethu uvelisa iimoto ukusuka kwi-6mm ukuya kwi-60mm ububanzi. Linganisa indawo ekhoyo kwindibano yakho - ungalibali ubude bomngxuma kunye nolwalathiso lwesixhumi. Imingxunya okanye izibiyeli eziqhelekileyo zokufakela zinokwenziwa ngokwezifiso, kodwa izixhobo ezenziwe ngokwezifiso zongeza iindleko kunye nexesha lokuqalisa.

5. Jonga iimfuno zokusingqongileyo nezobomi bonke

Ubushushu bokusebenza, ukufuma, uthuli, kunye nokungcangcazela konke kuchaphazela ubomi bemoto. Kwizicelo zangaphandle okanye zeemoto, khangela ukulinganiswa kwe-IP (umz., i-IP54). Kwiimveliso ezihlala ixesha elide (ngaphezulu kweeyure ezili-1000), cinga ngeebhrashi zesinyithi ezixabisekileyo okanye uyilo olungenabhrashi. Cela iingxelo zovavanyo lobomi kuthi.

Icebiso lokugqibela: soloko uvavanya umthwalo wakho wokwenyani. Amaphepha edatha yindawo yokuqala, kodwa ukusebenza kwehlabathi lokwenyani kunokwahluka. Cela iisampulu kwaye usebenzise eyakho isiqinisekiso. Injini ekhethwe kakuhle igcina iindleko, ixesha, kunye neentloko zewaranti.
