Basic qauv ntawm DC lub cev muaj zog

Lub hauv paus qauv ntawm DC lub cev muaj zog:

Ob feem ntawm stator thiab rotor

Stator muaj nuj nqi: Tsim lub ntsiab magnetic teb thiab mechanically txhawb lub cev muaj zog.

Stator muaj pes tsawg leeg: lub ntsiab sib nqus ncej, commutation ncej, ncej, kawg npog, bearing, thiab lwm yam.

Lub ntsiab qauv yog DC lub cev muaj zog

1. Lub ntsiab sib nqus ncej

Lub ntsiab sib nqus ncej muaj xws li lub ntsiab magnetic ncej hlau core thiab magnetic teb winding lub tes tsho rau nws, thiab nws lub luag hauj lwm tseem ceeb yog los tsim lub ntsiab magnetic teb. Qhov loj nyob rau hauv tus ncej hlau nplaum yog hu ua tus ncej xibtes, thiab nws txoj haujlwm yog ua kom cov hlau nplaum sib nqus hauv cov huab cua dhau los tsim nyog, kom lub teb winding tuaj yeem ruaj khov ntawm cov tub ntxhais hlau. Cov ncej hlau nplaum yog ib feem ntawm cov hlau nplaum sib nqus thiab yog ua los ntawm laminated steel phaj ntawm 1.0-1.5 hli. Lub teb winding yog mob nrog insulated tooj liab hlau.

2. Rov qab ncej

Lub commutation ncej yog los txhim kho kev sib hloov kev ua tau zoo ntawm armature tam sim no. Nws kuj muaj cov tub ntxhais hlau thiab windings, uas yog tsau ntawm ob lub ntsiab sib nqus ncej ntawm stator nrog screws.

3. Base

Lub thav duab yog siv los kho lub ntsiab sib nqus ncej, commutation ncej thiab lub kaus mom kawg ntawm ib sab tes, thiab ntawm qhov tod tes raws li kev txhawb nqa ntawm tag nrho lub cev muaj zog. Lub cev muaj zog yog tsau rau ntawm lub hauv paus nrog thauj tog rau nkoj screws. Ntawm qhov tod tes, nws kuj yog ib feem ntawm lub tshuab hluav taws xob sib nqus ntawm lub cev muaj zog, yog li nws yog ua los ntawm cam khwb cia hlau lossis steel phaj. Nias rau hauv.

4. Armature tub ntxhais

Lub armature core yog ib feem ntawm lub ntsiab magnetic ncej. Nws yog ua los ntawm silicon steel ntawv thiab muaj ib tug cylindrical zoo. Qhov saum npoo yog slotted, thiab cov pa tawm pivot winding yog embedded rau hauv lub qhov. Txhawm rau ntxiv dag zog rau qhov txias ntawm cov tub ntxhais hlau, axial qhov cua qhov qhov yog muab rau ntawm cov tub ntxhais hlau armature.

5. Armature winding

Lub armature winding yog qhov tseem ceeb rau DC lub cev muaj zog los tsim kom muaj hluav taws xob muaj peev xwm thiab hluav taws xob torque kom paub lub zog hloov pauv. Lub winding feem ntau yog ua los ntawm tooj liab hlau, qhwv nrog cov ntaub ntawv insulating, thiab embedded nyob rau hauv lub qhov ntawm lub armature core. Txhawm rau tiv thaiv kom tsis txhob muaj lub zog centrifugal los ntawm kev cuam tshuam cov winding tawm ntawm lub qhov, tus neeg xyuas pib winding yog wedged rau hauv lub qhov nrog ib lub qhov wedge.

6. txhuam cov cuab yeej

Cov khoom siv txhuam txhuam muaj xws li txhuam txhuam thiab txhuam txhuam ruaj rau ntawm stator, thiab tus txhuam txhuam tuav tuav zawv zawg kev sib cuag nrog lub commutator, yog li txuas lub armature winding thiab sab nraud tam sim no.

7. Commutator

Lub luag haujlwm ntawm lub tshuab hluav taws xob commutator yog hloov AC electromotive quab yuam los ntawm armature winding rau hauv DC electromotive quab yuam ntawm txhuam. Rau lub cev muaj zog, nws hloov cov DC tam sim no mus rau hauv AC DC ntawm armature winding, thiab xyuas kom meej tias tam sim no cov kev taw qhia ntawm armature conductor nyob rau hauv txhua tus ncej hlau nplaum tsis hloov, thiab ib tug tas li electromagnetic torque yog generated. Lub commutator yog tsim los ntawm ntau daim ntawv tooj liab cais los ntawm ib leeg. Cov nplooj ntawv tooj liab no hu ua commutator segments, thiab txhua ntu commutator txuas nrog armature winding. Daim duab kos duab ntawm commutator yog qhia hauv daim duab. Lub commutator yog cov qauv ntawm DC lub cev muaj zog thiab yooj yim los txheeb xyuas.
