Ukwethulwa kwenjini ye-DC engenamabhulashi kumathuluzi kagesi

Ngokuthuthuka kobuchwepheshe obusha bokulawula ibhethri kanye ne-elekthronikhi, izindleko zokuklama kanye nokukhiqiza zemoto ye-DC engenamabhulashi zincishisiwe kakhulu, futhi amathuluzi alula okushaja kabusha adinga imoto ye-DC engenamabhulashi athandwe kakhulu futhi asetshenziswa kabanzi. Isetshenziswa kabanzi embonini yokukhiqiza yezimboni, yokuhlanganisa kanye neyokulungisa, ikakhulukazi ngentuthuko yezomnotho, isidingo semindeni naso siya sikhuphuka, futhi izinga lokukhula lonyaka liphezulu kakhulu kuneleminye imboni.

2, uhlobo lohlelo lokusebenza lwenjini yamathuluzi kagesi aphinde ashajwe kabusha olulula

2.1 Injini ye-DC ebhulashiwe

Isakhiwo semoto ye-DC esivamile esingenamabhulashi sihlanganisa i-rotor (umgodi, umongo wensimbi, ukugoqa, i-commutator, i-bearing), i-stator (ikheyisi, i-magnet, isivalo sokugcina, njll.), ukuhlanganiswa kwebhulashi lekhabhoni, ingalo yebhulashi lekhabhoni nezinye izingxenye.

Isimiso sokusebenza: I-stator yemoto ye-DC ebhulashiwe ifakwe i-fixed main pole (magnet) kanye nebhulashi, kanti i-rotor ifakwe i-armature winding kanye ne-commutator. Amandla kagesi kagesi kagesi we-DC angena ku-armature winding ngebhulashi le-carbon kanye ne-commutator, ekhiqiza i-armature current. Insimu yamagnetic ekhiqizwa yi-armature current ixhumana nensimu yamagnetic eyinhloko ukuze ikhiqize i-torque kagesi, okwenza imoto ijikeleze futhi iqhube umthwalo.

Okubi: Ngenxa yokuba khona kwebhulashi lekhabhoni kanye ne-commutator, ukuthembeka kwenjini yebhulashi kubi, ukwehluleka, ukungazinzi kwamanje, impilo emfushane, kanye ne-commutator spark kuzodala ukuphazamiseka kwe-electromagnetic.

2.2 Injini ye-DC engenamabhulashi

Isakhiwo semoto ye-DC esivamile esingenamabhulashi sihlanganisa i-motor rotor (umgodi, umongo wensimbi, umazibuthe, ibheyaringi), i-stator (ikheyisi, umongo wensimbi, ukugoqa, inzwa, isembozo sokugcina, njll.) kanye nezingxenye zokulawula.

Isimiso sokusebenza: Imoto ye-DC engenamabhulashi yakhiwe ngomzimba wemoto nomshayeli, ingumkhiqizo ojwayelekile we-mechatronics. Isimiso sokusebenza sifana nemoto yebhulashi, kodwa ibhulashi le-commutator lendabuko kanye nebhulashi lekhabhoni kuthathelwa indawo yinzwa yesikhundla kanye nomugqa wokulawula, futhi isiqondiso samanje siguqulwa ngomyalo wokulawula okhishwa yisignali yokuzwa ukuze kufezwe umsebenzi wokushintshashintsha, ukuze kuqinisekiswe i-torque kagesi engaguquki kanye nokuqondisa kwemoto nokwenza imoto ijikeleze.

Ukuhlaziywa kwemoto ye-DC engenamabhulashi kumathuluzi kagesi

3. Izinzuzo kanye nokungalungi kokusetshenziswa kwemoto ye-BLDC

3.1 Izinzuzo zemoto ye-BLDC:

3.1.1 Isakhiwo esilula nekhwalithi ethembekile:

Khansela i-commutator, ibhulashi lekhabhoni, ingalo yebhulashi nezinye izingxenye, akukho ukushisela i-commutator, inqubo yokuqeda.

3.1.2 Impilo Yesevisi Ende:

Ukusetshenziswa kwezingxenye ze-elekthronikhi ukuze kuthathelwe indawo isakhiwo sendabuko se-commutator, kususwe injini ngenxa yebhulashi lekhabhoni kanye ne-commutator commutator spark, ukuguguleka komshini nezinye izinkinga ezibangelwa impilo emfushane, impilo yemoto yanda ngokuphindaphindiwe.

3.1.3 Ukusebenza kahle okuthule nokuphezulu:

Akukho bhulashi lekhabhoni kanye nesakhiwo se-commutator, gwema inhlansi ye-commutator kanye nokungqubuzana komshini phakathi kwebhulashi lekhabhoni kanye ne-commutator, okuholela emsindweni, ekushiseni, ekulahlekelweni kwamandla enjini, kunciphisa ukusebenza kahle kwenjini. Ukusebenza kahle kwenjini ye-DC engenamabhulashi ku-60~70%, kanye nokusebenza kahle kwenjini ye-DC engenamabhulashi kungafinyelela ku-75~90%

3.1.4 Ukulawulwa kwesivinini okubanzi kanye namakhono okulawula:

Izingxenye ze-elekthronikhi ezinembile kanye nezinzwa zingalawula ngokunembile isivinini sokuphuma, i-torque kanye nendawo yemoto, ziqaphela ukuhlakanipha nokusebenza okuningi.
