Umahluko phakathi kwebhrashi / brushless / stepper motors ezincinci? Khumbula le theyibhile

Xa uyila izixhobo ezisebenzisa iinjini, kuyafuneka ukuba ukhethe imoto ewufanelekela kakuhle umsebenzi ofunekayo.

 

Eli nqaku liza kuthelekisa iimpawu, ukusebenza kunye neempawu zeenjini ezixutywe, iimotor stepper kunye ne-brushless motors, ngethemba lokuba yireferensi kumntu wonke xa ukhetha i-motor.

 

Nangona kunjalo, kuba kukho iisayizi ezininzi zeenjini kudidi olufanayo, nceda uzisebenzise njengesikhokelo kuphela.Ekugqibeleni, kuyimfuneko ukuqinisekisa ulwazi oluthe kratya ngokusebenzisa iinkcukacha zobugcisa bemoto nganye.

Iimpawu zeenjini ezincinci
Iimpawu zeemotor ezinyathelayo, iimotor ezibrashwayo, kunye neemotor ezingenasibhrashi zishwankathelwa kwitheyibhile engezantsi.

 

i-motor ye-stepper
ibhrashi yemoto
IMoto yeBrushless
Indlela yokujikeleza
Ngokusebenzisa i-drive circuit, ukutshatyalaliswa kwesigaba ngasinye se-armature winding (isigaba esibini, isigaba sesithathu, kunye nesigaba sesihlanu) sinqunywe. I-armature current itshintshwa yi-sliding contact rectifier mechanism yeebrashi kunye nabahambisi. I-Brushless iphunyezwa ngokutshintshela imisebenzi yeebhrashi kunye nabahambi kunye nezinzwa zepoli kunye nokutshintsha kwe-semiconductor.
Qhuba isekethe
isidingo ngokungeyomfuneko isidingo
torque
Itorque inkulu. (ingakumbi torque ngesantya esiphantsi) I-torque yokuqala inkulu, kwaye i-torque ilingana ne-armature current. (Itorque inkulu ngokwesantya esiphakathi ukuya kwisantya esiphezulu)
isantya sokujikeleza
ngokomlinganiselo wegalelo lokubetha kwe-pulse frequency. Kukho indawo engaphandle kwenyathelo kuluhlu lwesantya esiphantsi Ilingana nombane osetyenziswa kwi-armature.Isantya siyancipha njengoko itorque yomthwalo isanda
ukujikeleza ngesantya esiphezulu
Ubunzima bokujikeleza ngesantya esiphezulu (kufuneka ucothe) Ukuya kuthi ga kumawaka aliqela e-rpm ngenxa yebrashi kunye nothintelo lwendlela yokuhambisa umhambisi Ukuya kuthi ga kumawaka aliqela ukuya kumashumi amawaka e-rpm
Ubomi bokujikeleza
Ukuzimisela ngokuzala ubomi.amashumi amawaka eeyure Ilinganiselwe ngebrashi kunye nokunxiba kwe-commutator. Amakhulu ukuya kumawaka eeyure Ukuzimisela ngokuzala ubomi. Amashumi amawaka ukuya kumakhulu amawaka eeyure
Iindlela zokujikeleza phambili kunye nokubuyisela umva
Kuyimfuneko ukutshintsha ukulandelelana kwesigaba sokuvuselela isekethe yokuqhuba Ukubuyisela umva i-polarity ye-pin voltage inokuguqulwa Kuyimfuneko ukutshintsha ukulandelelana kwesigaba sokuvuselela isekethe yokuqhuba
ulawulo
Ulawulo lwe-loop evulekileyo apho isantya sokujikeleza kunye nesikhundla (imali yokujikeleza) igqitywe yi-pulses yomyalelo inokwenzeka (kodwa kukho ingxaki yokuphuma kwinqanaba) Ukujikeleza kwesantya rhoqo kufuna ulawulo lwesantya (ulawulo lwempendulo usebenzisa inzwa yesantya). Ulawulo lweTorque lulula kuba itorque ilingana neyangoku
Ukufikelela ngokulula
Kulula: iintlobo ezininzi Kulula: abavelisi abaninzi kunye neentlobo, ezininzi iinketho Ubunzima: iimotor ezinikezelweyo ikakhulu kwizicelo ezithile
ixabiso
Ukuba isekethe yokuqhuba ifakiwe, ixabiso libiza kakhulu. Ixabiso eliphantsi kuneenjini ezingena brushless Ngokwentelekiso, iinjini ezingabizi kakhulu zixabisa kancinci ngenxa yokuphuculwa kwemagnethi. Ukuba isekethe yokuqhuba ifakiwe, ixabiso libiza kakhulu.

 

Ukuthelekiswa kokusebenza kweenjini ezincinci
Ukuthelekisa ukusebenza kweemoto ezincinci ezahlukeneyo zidweliswe kwitshathi yeradar.

 

Iimpawu ze-Speed-torque zeemoto ezincinci
Iimpawu zesantya-torque zemoto encinci nganye zishwankathelwa ngezantsi. Inokuthi ithathelwe ingqalelo into yokuba i-brushless motor kunye ne-brushed motor ziyafana.

 


 

Isishwankathelo
 

1) Xa ukhetha iimotor ezinje ngeenjini ezibrashwayo, iimotor stepper kunye nebrushless motors, iimpawu, ukusebenza kunye neempawu zokuthelekisa iziphumo zeenjini ezincinci zinokusetyenziswa njengesalathiso sokhetho lweemoto.

 

2) Xa ukhetha iimotor ezifana neemoto ezixutywe, iimotor stepper kunye nebrushless motors, iimotor zodidi olufanayo zibandakanya iinkcukacha ezahlukeneyo, ngoko ke iziphumo zokuthelekisa iimpawu, ukusebenza kunye neempawu zeenjini ezincinci zenzelwe ireferensi kuphela.

 

3) Xa ukhetha iimotor ezinje ngee-motor brushed, stepper motors kunye ne-brushless motors, ekugqibeleni kuyafuneka ukuba kuqinisekiswe ulwazi oluneenkcukacha ngeenkcukacha zobugcisa zemoto nganye.
