Universal lub cev muaj zogyog ib hom ntawm lub cev muaj zog uas lub stator coil (xws li excitation winding) thiab rotor coil (xws li armature winding) txuas nrog lub zog mov los ntawm txhuam thiab commutator hauv series.
Ib-theem Universal TsavFeem ntau hu ua series lub cev muaj zog lossis lub hom phiaj dav dav lub cev muaj zog.Universal lub cev muaj zog yog ib yam ntawm lub cev muaj zog uas lub stator coil (xws li excitation winding) thiab rotor coil (namely armature winding) txuas nrog lub zog los ntawm txhuam thiab commutator hauv series. . Ib-theem Universal lub cev muaj zog feem ntau hu ua series motor lossis lub hom phiaj dav dav.
Vim lub hauv paus qauv ntawm lubUniversal lub cev muaj zog zoo ib yam li DC Universal lub cev muaj zog, tab sis nws tuaj yeem siv rau AC, yog li lub hauv paus ntsiab lus ntawm nws qhov kev sib hloov torque kuj tuaj yeem qhia los ntawm lub hauv paus ntsiab lus ntawm DC lub cev muaj zog.
Raws li pom nyob rau hauv daim duab 1, ib tug tsis tu ncua tam sim no voltage yog siv rau qhov kawg ntawm cov pa roj carbon txhuam A thiab B, thiab tam sim no nyob rau hauv winding ntws mus rau hauv cov pa roj carbon txhuam A, ntws los ntawm tus neeg xyuas pib nyob rau hauv lub N ncej los ntawm tus neeg xyuas pib nyob rau hauv lub S ncej, thiab ces ntws tawm ntawm cov pa roj carbon txhuam B. Lub winding txav vim lub magnetic teb interacts nrog cov magnetic teb generated los ntawm tam sim no nyob rau hauv tus neeg xyuas pib.
Yog hais tias tus neeg xyuas pib raug xa mus rau lwm lub teb chaws polar magnetic, cov kev taw qhia tam sim no nyob rau hauv winding yuav hloov raws li qhov kev txiav txim ntawm txhuam thiab commutator, uas yog, tam sim no cov kev taw qhia nyob rau hauv tus neeg xyuas pib nyob rau hauv ib tug tej yam polar magnetic teb yuav nyob twj ywm unchanged, yog li ntawd. lub zog kev taw qhia ntawm winding yuav nyob twj ywm tsis hloov. Yog li ntawd, lub torque generated los ntawm winding yog ib txwm unidirectional.
Vim hais tias Universal lub cev muaj zog, nyob rau hauv cov ntaub ntawv ntawm AC fais fab mov, stator tam sim no thiab rotor tam sim no yuav hloov nyob rau tib lub sij hawm, uas yog, stator flux thiab armature tam sim no yuav hloov nyob rau tib lub sij hawm, raws li sab laug tes txoj cai ntawm lub cev muaj zog, nyob rau hauv lub rooj plaub ntawm flux thiab armature tam sim no hloov kev taw qhia, rotor kauj yuav tsis hloov.
Txawm hais tias lub polarity ntawm lub hwj chim mov hloov ntau zaus, lub rotor yeej ib txwm tswj lub kauj, uas yog lub hauv paus ntsiab lus ntawm Universal motor.
Ib-theem Universalmotor feem ntau yog tsim los ntawm stator, armature, bracket, txhuam tuav thiab commutator.
Stator: Lub stator yog cov neeg kho tshuab kev txhawb nqa ntawm tag nrho lub cev muaj zog, uas yog siv los tsim lub ntsiab sib nqus flux. Nws yog tsuas yog tsim los ntawm stator hlau core thiab excitation winding.
Armature: Armature, tseem hu ua rotor, yog qhov kev sib hloov ntawm lub cev muaj zog, yog qhov tseem ceeb tshaj plaws ntawm lub cev muaj zog. Lub luag haujlwm ntawm lub rotor yog los tsim hluav taws xob hluav taws xob torque, uas hloov hluav taws xob hluav taws xob rau hauv lub zog siv tshuab. Nws muaj ib tug rotating ncej, ib tug hlau core, armature winding, ib tug commutator thiab ib tug txias kiv cua.
Commutator: Commutator muaj ntau yam khoom siv sib txuas. Feem ntau, mica ntawv rwb thaiv tsev yog siv nruab nrab ntawm daim ntawv thim rov qab thiab cov ntawv thim rov qab, thiab cov iav fiber ntau phenolic yas yog nias rau hauv ib nrab hli zawj ntawm ob qho kawg ntawm sab qis ntawm daim ntawv thim rov qab, kom txhua daim ntawv thim rov qab tuaj yeem ua tiav.
Carbon txhuam tuav: Carbon txhuam tuav yog tsim los ntawm chassis, txhuam tuav, caij nplooj ntoos hlav thiab carbon txhuam.
