Umhlinzeki weyunithi yamabhuleki uyakukhumbuza: ngokuvamile kunezindlela ezimbili zokubhuleka i-asynchronous motor enezigaba ezintathu, eyodwa i-mechanical braking kanti enye i-electric braking. Lokhu okubizwa ngokuthi yi-braking ukunikeza i-asynchronous motor enezigaba ezintathu i-torque ephambene nendawo lapho ijika khona ukuze ime ngokushesha.
Ama-motor asynchronous ezigaba ezintathu asetshenziswa kabanzi emikhakheni ehlukahlukene yezimboni. Ezisetshenziswa ezingokoqobo, ukuze kuqinisekiswe ukuphepha nokusebenza kahle kwenqubo yokukhiqiza, ngokuvamile sidinga ukubhuleka isilawuli semoto, futhi ukubhuleka ukusetshenziswa kwamandla kuyindlela evamile yokubhuleka.
Ukubhuleka okudla amandla kuyindlela yokusebenzisa izici zemoto ukufeza ukubhuleka. Ngale ndlela, i-torque ye-motor ishintshwa ngokushintsha usayizi wokumelana kwangaphandle kwe-motor, ngaleyo ndlela kufinyelele umphumela wokubhuleka.
Umgomo wesigaba sesithathu se-asynchronous motor energy ukusetshenziswa braking ungachazwa ngalezi zinyathelo ezilandelayo:
Isinyathelo sokuqala ukulungisa i-impedance ye-motor. Imvamisa, kune-impedance eyengeziwe kumjikelezo wemoto, futhi ngokulungisa usayizi walokhu kumelana, i-torque ye-motor ingashintshwa. Lapho i-motor idinga i-braking, sikhulisa ukuvinjelwa kwalokhu kumelana, ngaleyo ndlela sinciphisa i-torque ye-motor.
Isinyathelo sesibili ukushintsha indlela injini esebenza ngayo. Ekusebenziseni amandla amabhuleki, singashintsha indlela injini esebenza ngayo: ukushintsha usuka ekunikezeni amandla okuvamile ukuya kugesi obuyela emuva. Ngokushintsha ukunikezwa kwamandla, singashintsha isiqondiso sokujikeleza kwemoto futhi sisebenzise i-torque engalungile eyenzayo ukuze sifinyelele umphumela wokubhuleka.
Isinyathelo sesithathu ukulawula inqubo yokubhuleka ngokuqapha isivinini kanye namandla emoto. Ngokusebenzisa izinzwa ezifanele kanye nezinhlelo zokulawula, isimo sokusebenza semoto singabhekwa ngesikhathi sangempela futhi ukumelana namandla angalungiswa njengoba kudingeka ukuze kuzuzwe umphumela wokubhuleka owufunayo. Phakathi nenqubo yokubhuleka, singasebenzisa nomgomo wokulawula impendulo ukuze silawule ngokunembile itorque nesikhathi sokubhuleka semoto, ngaleyo ndlela sizuze ukubhuleka okuzinzile nokunembile.
Ngokuvamile, i-asynchronous motor ukusetshenziswa kwe-asynchronous motor braking ifinyelelwa ngokushintsha usayizi wokumelana nemoto yangaphandle, ukushintsha indlela yokunikezwa kwamandla emoto kanye nokulawula ngamandla isimo sokusebenza kwemoto. Le ndlela yokubhuleka inezinzuzo zomphumela olula, othembekile, omuhle wokubhuleka, kanye nezindleko eziphansi, futhi yamukelwa kabanzi ezinhlelweni ezisebenzayo zezimboni. Ngesikhathi esifanayo, ngokulawula okunengqondo nokulungiswa, ingafinyelela ukulawula okunembile kwenqubo ye-motor braking, ithuthukise ukuphepha nokusebenza kahle kwenqubo yokukhiqiza.
