ALTERNATOR ASSEMBLY W23601.08100.01W

Thaum cov hluav taws xob sab nraud dhau los ntawm cov txhuam hniav los muab tam sim no rau qhov excitation winding, ib qho magnetic teb yog generated, ua rau cov pawl ncej yuav magnetized li N ncej thiab S ncej. Thaum lub rotor rotates, lub magnetic flux alternates nyob rau hauv lub stator windings. Raws li lub hauv paus ntsiab lus ntawm electromagnetic induction, ib qho alternating induced electromotive quab yuam yog tsim nyob rau hauv peb -theem stator windings. Qhov no yog lub hauv paus ntsiab lus ntawm kev tsim hluav taws xob hauv lub alternator.

Lub tshuab hluav taws xob synchronous rotor uas tau tsav los ntawm tus thawj txav (piv txwv li, lub cav) tig ntawm qhov nrawm ntawm n (rpm), thiab peb -theem stator windings ua rau muaj kev hloov hluav taws xob. Yog hais tias lub stator windings txuas nrog ib qho hluav taws xob load, lub cev muaj zog tuaj yeem tsim hluav taws xob hloov hluav taws xob, thiab cov khoom siv hluav taws xob hloov pauv mus rau qhov tam sim no ncaj qha los ntawm tus choj rectifier hauv lub tshuab hluav taws xob thiab cov zis tawm los ntawm cov khoom siv hluav taws xob.

Lub alternator yog tsim los ntawm ob ntu: stator winding thiab rotor winding. Peb -theem stator winding yog sib npaug ntawm cov vaj tsev nyob ntawm lub kaum sab xis ntawm 120 degrees ntawm ib leeg. Lub rotor winding muaj ob tug ncej claws. Thaum lub rotor winding txuas nrog ib qho ncaj qha tam sim no, nws zoo siab heev. Ob tug ncej claws tsim N ncej thiab S ncej. Cov kab sib nqus ntawm lub zog pib los ntawm N ncej, hla dhau qhov sib txawv ntawm huab cua, nkag mus rau hauv stator core, thiab rov qab mus rau tus ncej S uas nyob ib sab. Thaum lub rotor tig, lub rotor winding yuav txiav cov kab sib nqus ntawm lub zog, ua rau lub zog sinusoidal electromotive nrog lub kaum sab xis hluav taws xob sib txawv ntawm 120 degrees hauv stator winding. Qhov no yog peb -theem alternating tam sim no. Tom qab ntawd nws hloov mus rau hauv cov tam sim no ncaj qha los ntawm cov khoom siv rectifier muaj li ntawm diodes.

Roj teeb zoo davhlau ya nyob twg → Charging qhia lub teeb → Regulator contact → Excitation winding → Av → Battery negative terminal. Lub sijhawm no, lub teeb qhia kev them nyiaj yuav qhib vim tias muaj tam sim no dhau los ntawm nws.

Txawm li cas los xij, tom qab lub cav pib, raws li lub tshuab hluav taws xob nrawm nce, cov zis hluav taws xob ntawm lub tshuab hluav taws xob kuj tseem nce ntxiv. Thaum cov zis hluav taws xob ntawm lub tshuab hluav taws xob sib npaug ntawm qhov hluav taws xob ntawm lub roj teeb, lub peev xwm ntawm "B" thiab "D" terminals ntawm lub tshuab hluav taws xob yog tib yam. Lub sijhawm no, lub teeb qhia kev them nyiaj yuav tawm mus vim tias qhov sib txawv ntawm ob qhov kawg yog xoom. Qhov no qhia tau hais tias lub tshuab hluav taws xob ua haujlwm ib txwm ua, thiab cov khoom siv hluav taws xob tau muab los ntawm lub tshuab hluav taws xob nws tus kheej. Peb -theem hloov tam sim no tsim los ntawm peb-theem windings nyob rau hauv lub tshuab hluav taws xob yog rectified los ntawm diodes, thiab ces tso zis raws li cov tam sim no ncaj qha, uas muab lub hwj chim rau lub load thiab tsub lub roj teeb.
