Mashandiro anoita jenareta yemotokari
Nheyo huru yekushanda kwejenareta yemotokari yakavakirwa pamutemo we electromagnetic induction. Alternating current inogadzirwa nekufamba kwe rotor ne stator, uye yozoshandurwa kuita direct current ne rectifier yekushandiswa kwemotokari.
Nzira chaiyo yekushanda inogona kukamurwa kuita matanho makuru anotevera:
Kushandurwa kwesimba uye kuumbwa kwesimba remagineti
Injini inotyaira rotor yejenareta nepabhandi kuti itenderere (mechanical energy input), uye mawindings anonakidza ari parotor anogadzira simba remagineti mushure mekuwedzerwa simba (N pole neS pole zvinogoverwa zvakasiyana).
Padanho rekutanga (pakumhanya kwakaderera), bhatiri rinopa simba rekuburitsa simba (maitiro akasiyana ekuburitsa simba) kuti rive nechokwadi chekuti simba remagineti rasimbiswa.
kugadzirwa kwemagetsi emagetsi ekugadzira induction
Kana rotor ikatenderera, simba rayo remagineti rinofamba zvichienzaniswa ne stator winding, uye mutsetse we magnetic inductance uri mu stator winding unochekwa kuti ugadzire three-phase alternating current.
Mawindings e stator anoparadzirwa paAngle yemagetsi ye120 degrees, izvo zvinowedzera kuenzana kwe AC yechikamu chetatu.
Rectifier uye kubuda
Kubuda kwemagetsi anochinjana ne stator kunoshandurwa kuita magetsi akananga kuburikidza nebhiriji rinogadzirisa magetsi (kazhinji kacho chimiro che 6 - kana 9-tube) chine ma diode, ayo anoshandiswa nemidziyo yemotokari uye anochaja bhatiri.
Magadzirirwo emagetsi akagadzirwa kuti ave nechokwadi chekuti magetsi anoyerera nenzira imwe chete, senge jenareta ine machubhu mapfumbamwe inovandudza kufambiswa kwemhepo nekuwedzera madiode.
Kudzora Kugadzikana uye Kudzora Voltage
Chinodzora magetsi chinogadzirisa simba remagetsi zvichienderana nemamiriro ebhatiri uye kudiwa kwemutoro, uye chinochengetedza simba remagetsi rinobuda riri pakati pe13.8-14.8V.
Kana kumhanya kwejenareta kwakakwira zvakakwana (danho rekuzvikurudzira) uye voltage yekubuda yakaenzana nevoltage yebhatiri, chiratidzo chekuchaja chinodzima, zvichiratidza kuti sisitimu inoshanda zvakanaka.
kuwedzera kwetekinoroji: majenareta emotokari emazuva ano anowanzo batanidza module yekutonga yakangwara, pamwe chete neCAN bus kuti iwane kugona kwekushandisa simba. Dhizaini yacho inofanirwa kuyera kushanda kwemagetsi nekukurumidza uye kushanda kwekupisa munzvimbo dzinopisa zvakanyanya, uye mamwe mamodheru anoshandisa ma alternator asina mabhurashi kuderedza zvinodiwa pakugadzirisa.
Voltage inoshanda yejenareta yemotokari inowanzo kuve pakati pe13.5-14.5 volts, kukosha kwayo kuchagadziriswa zvinoenderana nehurongwa hwevoltage regulator uye kumhanya kweinjini.
Chirevo chikuru
Mhando yemagetsi yakajairika
Voltage inobuda mujenareta yemotokari zhinji dzinotakura vanhu (12V system) yakagadzikana pa13.5-14.5 volts, inova ndiyo nzira yakachengeteka ye floating charge voltage yebhatiri, iyo inogona kuve nechokwadi chekuti michina yemagetsi inowanikwa uye kudzivirira kubhadharisa zvakanyanya.
Mumamiriro ezvinhu chaiwo (akadai sekutanga kutonhora), panogona kunge paine kuchinja kwechinguva kwe12.6-14.5 volts, asi hazviwanzoitiki kana ikaramba ichidarika huwandu uhu.
Mhedzisiro ye voltage isina kujairika
pasi pe13 volts: Bhatiri harina chaji yakakwana, izvo zvinogona kukonzera kuoma kwekutanga kana kusagadzikana kwemagetsi kumudziyo wemagetsi
yakakwirira kupfuura 14.5 volts: inokurumidza kubuda kwe electrolyte yebhatiri, inopfupisa hupenyu hwebhatiri re lead-acid, uye inogona kupisa zvikamu zvemagetsi
Mazano ekuyedza
Shandisa multimeter kuyera voltage inobuda yejenareta. Kana injini yatanga, ichengetedze pa2000 RPM. Kana mudziyo wemagetsi wemotokari wadzimwa, voltage inofanira kunge yakagadzikana pa14.2±0.3 volts
Kana voltage isiri yakanaka, tarisa chinogadzirisa magetsi, chinodzora magetsi, uye bhandi
Cherechedza: "17-15 volts" nedzimwe data dzakataurwa mumhedzisiro yekutsvaga hadzina kuenderana, uye mushure mekuongororwa, zvinowanikwa kuti zvinobva mumatanho asina simba uye hazvienderane nemitemo yemazuva ese yekuchengetedza mota, saka hazvigamuchirwi.
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonerei kana muchida zvigadzirwa zvakadaro.
Zhuo Meng Shanghai Auto Co., Ltd. yakazvipira kutengesa zvikamu zvemotokari zveMG&750 zvinogamuchirwa Kutenga.
