Ibibazo icumi bito byerekeranye no kugenzura moteri

Ibibazo icumi by'ingenzi bijyanye Igenzura rya moteri

Tekinoroji yo kugenzura ibinyabiziga iri mu mutima wogukora inganda, ibinyabiziga byamashanyarazi, sisitemu yo murugo ifite ubwenge, nibindi byinshi. Kuri ba injeniyeri n'abakunzi b'ikoranabuhanga kimwe, gusobanukirwa amahame n'ibibazo byayo ni ngombwa.

Ikibazo 1: Niyihe ntego nyamukuru yo kugenzura ibinyabiziga?

Intego yo kugenzura ibinyabiziga ni ukugenzura voltage, ikigezweho, cyangwa inshuro kugirango ugere kumusaruro wifuzwa mumuvuduko, torque, cyangwa umwanya. Intego z'ingenzi zirimo:

• Igisubizo cyukuri(urugero, kugenzura hamwe muri robo yinganda)

• Imikorere ikoresha ingufu(urugero, guhitamo gukoresha ingufu muri EV)

• Kwanga guhungabana bikabije(urugero, guhagarika drone mubihe byumuyaga)

Ikibazo 2: Kuki kugenzura gufunga-gufunga bikenewe?

Kugenzura-gufungura (urugero, gukoresha moteri mu buryo butaziguye) biroroshye ariko bifite inenge: ihinduka ryumutwaro utunguranye cyangwa ihungabana ryibidukikije ritera ihindagurika ryihuta. Igenzura rifunze-rikoresha ibitekerezo-byukuri (urugero, ibimenyetso bya kodegisi) kugirango bikosore amakosa. Ibisabwa birimo:

• Sisitemu ya Servo isaba ± 0.01mm ihagaze neza

• Guhuza igorofa neza

Ikibazo 3: Nigute PWM ituma amabwiriza yihuta?

Impinduka z'ubugari bwa pulse (PWM) ihindura impuzandengo ya voltage muguhindura imbaraga byihuse / kuzimya. Urugero:

• 50% yumusoro utanga 50% ya voltage yo gutanga

• Umuvuduko mwinshi wo guhinduranya (urugero, 20kHz) bigabanya kunyeganyega kwa moteri
  Ibyiza: Igihombo gito cyumuzunguruko, guhuza nabagenzuzi ba digitale (urugero, MCUs).

Ikibazo 4: Kuki kugenzura vector (FOC) gukora neza?

Uburyo gakondo (urugero, kugenzura V / F) birengagiza guhuza imirima ya magneti na torque. Igenzura-Imirima-Igenzura (FOC) ikuramo ibi ikoresheje guhuza ibikorwa (Clarke-Park ihinduka), igabanyamo ibyiciro bitatu.kwishimanatorqueIbigize. Ibi bigana imikorere ya moteri ya DC, kuzamura imikorere kugeza kuri 15% (urugero, muri compressor ya AC-variable).

Ikibazo 5: Nigute igenzura ridafite sensor igereranya umwanya wa rotor?

Sensorless tekinike ikoreshainyuma-EMF indorerezicyangwainshinge nyinshigushishoza umwanya wa rotor, nibyiza kubiciro-byoroshye cyangwa byizewe cyane:

• Drone ESCs (kwirinda kunanirwa kwa sensor)

• Abafana bo murugo (kugabanya ibiciro byibyuma)
  Ubucuruzi-buke: Hasi gahoro gahoro imikorere nuburyo bwa sensor.

Ikibazo 6: Kuki gutangira moteri bigenda byiyongera?

Guhagarara, inyuma-EMF ni zeru, itera "umuyoboro ufunze-rotor" (5-7 × yagenwe). Ibisubizo birimo:

• Inzira yoroshye(gahoro gahoro kwiyongera)

• Guhindura inyenyeri-delta(kugabanya ingufu za mbere)

Ikibazo 7: Nigute ushobora guhagarika ibinyeganyega na moteri?

Impamvu zisanzwe zirimo imashini ya resonance hamwe na electromagnetic ihuza. Ingamba zo kugabanya ibicuruzwa:

• Guhagarika guhuza (urugero, SVPWM hamwe na optimizasiyo yo guhinduranya)

• Kwirinda imashini ya resonance ya zone (ukoresheje scanne ya frequency)

• Algorithms ikora neza (urugero, kugenzura icyitegererezo)

Ikibazo 8: Kuki gucunga ubushyuhe ari ngombwa?

Igihombo cya moteri (umuringa, icyuma) bibyara ubushyuhe, bishobora guhura na magnetiki ihoraho cyangwa kwangirika. Ibishushanyo mbonera:

• Ubushyuhe (urugero, NTC thermistors) kugirango ikurikirane igihe

• Sisitemu yo gukonjesha (gukonjesha ikirere / amazi, imiyoboro yubushyuhe)

Ikibazo 9: Nigute ushobora guhitamo imashini igenzura moteri?

• MCUs: Kubikorwa bito-bigoye (urugero, urukurikirane rwa STM32)

• DSPs: Kubara byihuse (urugero, TI C2000)

• FPGAs: Ultra-low ubukererwe busaba (urugero, sisitemu nyinshi-moteri)

Ikibazo 10: Niki gikurikira muburyo bwa tekinoroji yo kugenzura ibinyabiziga?

• Kwishyira hamwe kwa AI: Imiyoboro ya neural isimbuza intoki PID guhuza

• Ibikoresho bya SiC: Gutezimbere uburyo bwo guhinduranya ibintu byinshi

• Impanga: Kwihutisha iterambere binyuze muri prototyping
