Uyini umehluko phakathi kwe-brushless blower kanye ne-brushed blower?(1)
I. Umehluko kumgomo wokusebenza
- Isifutho esinomshini wokubhula
Ama-blower asebenzisa i-brush asebenzisa i-mechanical commutation, izigxobo zikagesi azinyakazi futhi i-coil iyajikeleza. Uma injini isebenza, i-coil kanye ne-commutator ziyajikeleza, omakethi kanye namabhulashi e-carbon awajikelezi, futhi ushintsho olushintshanayo lwesiqondiso samanje se-coil lwenziwa yi-phase changer kanye namabhulashi ajikeleza nenjini. Ama-electrode e-carbon ayashelela kuma-terminal e-coil ukuze kufezwe ushintsho lwesiqondiso, olubizwa ngamabhulashi e-carbon.
Ukushelela komunye nomunye kuzohlikihla amabhulashi ekhabhoni futhi kubangele ukuguguleka, kudinga ukushintshwa njalo kwamabhulashi; ukushintshana phakathi kwamabhulashi ekhabhoni kanye nama-coil lugs kuzoholela ezinhlansini zikagesi, kudale amagagasi kagesi aphazamisa imishini kagesi.
- Isifutho esingenamabhulashi
Izifutho ezingenamabhulashiukuthatha ukushintshashintsha kwe-elekthronikhi, ikhoyili ayinyakazi, izigxobo zikamazibuthe ziyajikeleza. Umsebenzi wokushintsha kwesigaba ushiywa kusekethe yokulawula kusilawuli (ngokuvamile inzwa yeHall + isilawuli, ubuchwepheshe obuthuthukisiwe kakhulu yi-magnetic encoder) ukuze uqedele; Izinto zeHall zizwa indawo yezigxobo zikamazibuthe zama-magnets ahlala njalo, ukuze isekethe lika-elekthronikhi lishintshe isiqondiso samanje ku-khoyili ngesikhathi sangempela ukuze lishayele imoto.
II. Umehluko ekulawulweni kwesivinini
- Isifutho sebhulashi -- Ukulawulwa kwesivinini se-voltage esiguquguqukayo
Kungukulungisa i-voltage yokuphakelwa ephezulu nephansi, ukushintsha amandla ensimu yamagnetic, ukufeza injongo yokushintsha isivinini; Ukulawulwa kwesivinini se-voltage eguquguqukayo.
- Isifutho esingenamabhulashi--Ukulawulwa kwesivinini semvamisa
Kungukulungisa i-voltage yokunikezwa kwamandla engashintshiwe, ukushintsha isignali yokulawula ye-ESC ukuze kufezwe injongo yokushintsha isivinini sokujikeleza;
