Piv txwv - nyob qhov twg lub electric tsav yog siv. Kev siv cov hluav taws xob motors

Lub cev muaj zog converts hluav taws xob lub zog mus rau hauv cov neeg kho tshuab zog. Nws muaj ib tug stator (los yog anchors) thiab rotor. Xws li ib tug ntaus ntawv tau txais heev ntau nyob rau hauv tag nrho cov cheeb tsam ntawm kev lub neej. Tsaug rau cov hluav taws xob motors yuav hloov nyob rau hauv ntau qhov chaw ntawm tib neeg ua hauj lwm rau lub tshuab ua hauj lwm. Ntau hom ntawm motors thiab nrhiav seb qhov twg hluav taws xob motors yog siv (saib cov piv txwv. Hauv qab no).

hauv paus ntsiab lus ntawm cov lag luam

Cov hluav taws xob lub cev muaj zog yog heev tsuas ua hauj lwm. Nws yog raws li nyob rau hauv lub hauv paus ntsiab lus ntawm electromagnetic induction. Lub installation muaj xws li ib tug taag ib feem - ib tug stator mounted nyob rau hauv AC motors thiab synchronous los yog asynchronous hom inductor (DC tsav), thiab lub rotor, i.e. lub rooj noj feem rau synchronous thiab asynchronous hom, thiab anchors rau lub DC pab kiag li lawm.

Rotors yuav ua tau luv luv-circuited (nas tawb hom) thiab ib theem winding (ris hauv qab lub nplhaib system). Mob qhov twg rau tom kawg hom cev muaj zog yog siv, yog asynchronous hom ntaus ntawv rau kom txhob muaj tam sim no thiab ceev cov kev cai.

A rooj noj feem ntawm lub DC ntaus ntawv los yog kev khiav hauj lwm rau txoj ntsiab cai no yog hu ua ib tug universal lub cev muaj zog armature. Universal lub cev muaj zog - ib tug DC tsav muaj ib tug tshwm sim stimulation i.e. series kev twb kev txuas thiab lub armature winding. Reactance DC tsis tau. Yog li ntawd, los ntawm tshem qhov hluav taws xob chav tsev ntawm lub li, nws yuav khiav, tshwj xeeb tshaj yog yog hais tias tus mains voltage thiab tsawg tam sim no siv - qhov.

alternating tam sim no motors

Cov units yog AC thiab DC. Nyob rau hauv tag nrho cov chaw nyob qhov twg lub electric tsav yog siv, feem ntau nws muaj AC. Qhov no lub cev muaj zog muaj ib tug yooj yim ua hauj lwm hauv paus ntsiab lus thiab yog ib qho yooj yim mus ua hauj lwm. Lub tsuas tseem ceeb drawback yog uncontrolled ceev.

Electric motors tej zaum yuav AC nrog ib tug los yog ntau tshaj theem. Devices, uas siv AC tsav, yog cov tsheb uas tsis yuav tsum tau kho cov kev ceev. Tej zaum lawv yuav muaj ntau lub hom phiaj (mills, twj, tshuab cov cuab yeej rau ua hauj lwm ntoo, thiab thiaj li nyob). Lawv thickness yog nruab nrab ntawm ob lub thiab kaum ob tug puas kilowatts saum toj no.

DC motors

Electric DC motors yuav muaj, ua ke nrog lub serial thiab thaum uas tig mus mixed compound thiab stator armature windings. Lawv kom zoo dua yog hais tias lub N yav dhau los saib: muaj peev xwm mus kom kev cai. Txawm li cas los, lub lag luam yuav tsum tau siv dag zog yuam.

Cov motors yog brushless thiab collector.

Brushless los yog valve - lub tshuab uas khiav lag luam nyob rau hauv ib tug kaw system nrog ib tug sensor uas detects cov hauj lwm ntawm ib tug rotor thiab ib tug tswj system.

Commutator motors yuav ua tau nws tus kheej-pog (thaum uas tig mus, serial los yog mixed) thiab cov neeg sab nraud excitation.

Devices, qhov twg DC motors siv los yog, piv txwv li, hluav taws xob tsheb thiab ntau yam siv cov cav tov.

asynchronous views

Cov feem ntau siv peb-theem nas tawb induction lub cev muaj zog. Nyob rau hauv cov ntaub ntawv no, lub rotating magnetic teb penetrates rau hauv lub luv luv-circuited rotor winding, vim uas tam sim no induction tshwm sim. Nws yog hu ua asynchronous vim hais tias cov kev sib hloov ntawm lub rotor yog tsis sib npaug zos rau cov kev sib hloov ntawm lub magnetic stator.

Kev siv ntawm asynchronous motors ntaus ntau nyob rau hauv ntau ceg ntawm kev lag luam, nyob rau hauv tsev neeg cov khoom siv (tub yees, ntxuav cov tshuab, cov tshuab cua txias), nyob rau hauv kev ua lag luam, xws li ntoo thiab hlau, raws li zoo raws li weaving. Lawv ua hauj lwm stability ntawm lwm hom, yog tsis tshua kim thiab yooj yim rau koj khiav lag luam.

simultaneous saib

Synchronous lub cev muaj zog rotor muaj ib tug zoo tsim, qhov no yog ib feem yog sawv cev los ntawm hluav taws xob los yog tas mus li cov hlau nplaum. kev sib hloov zaus nyob rau hauv cov ntaub ntawv no coincides nrog lub stator magnetic rotor zaus.

Qhov no zoo ntawm electric motors tej zaum yuav siv nyob rau hauv siv noj, yog tias yuav tsum reactive hwj chim cov nyiaj, thiab nyob rau hauv ib co lwm tus neeg mob.

Cov ntaub ntawv ntawm tshwm sim ntawm torque

Los ntawm txoj kev muaj tus torque electric motors muab faib mus rau hauv hysteresis thiab Magneto.

Feem ntau nyob rau hauv cov tshuaj industries siv motors magnetoelectric hom. Tej zaum lawv yuav tsis tu ncua, thiab alternating tam sim no. universal motors kuj ua ib ke.

Tab sis qhov kev lag luam, qhov twg hluav taws xob motors siv, hysteresis, tsis tau hu ua heev. Feem ntau, cov pab kiag li lawm yog unconventional nyob rau hauv qhov kev lag luam tsis tshua muaj siv. Feem ntau ntawm lawv yog siv nyob rau hauv gyroscopes, lub sij hawm txee, raws li zoo raws li lub suab txias ntaus ntawv thiab duab.

Universal motors collector hom

Qhov twg thov fais universal collector hom? Yog tsis muaj lawv, tsis txhob khiav lag luam cov muaj thiab khoom vaj khoom tsev, xws li cov kiv cua, juicers, nqaij grinders, lub tshuab nqus tsev, tub yees thiab cov zoo li. Lawv ua hauj lwm thiab xa mus rau DC hwj chim ntawm ib puas thiab kaum thiab ob puas thiab nees nkaum volts, thiab AC 127 thiab 220 volts.

Lub apparatus ntawm motors li bipolar DC motors muaj ib tug zoo ib yam ntxhov siab.

Ntawm no recruited tsis tsuas thauj tog rau nkoj ntawm hluav taws xob steel ntawv yam, tab sis tus ncej, thiab cov yoke, nws yog ib tug taag ib feem ntawm lub magnetic nyob ntawm tej.

Lub excitation Winding tej zaum yuav nrog nyob rau hauv ib thiab lwm yam sab ntawm lub armature. Qhov no thiaj li cuam tsim los ntawm ib tug lub cev muaj zog. Lub ceev tib yam thiab ntawm qhov, thiab thaum twg ib tug alternating tam sim no yog tiav los ntawm qhov kev siv ntawm lub teb winding nrog ub. Qhov txawv tsuas yog lus dag nyob rau hauv lub fact tias nws yog siv nkaus ntawm lub DC network thiab cov AC - tsuas yog cov.

Lub torque tau los ntawm qhov tam sim no reacting nrog lub magnetic flux teb.

Tej motors muaj ib tug muaj peev xwm ntawm ib tug tag nrho ntawm tsib mus rau rau puas watts (tab sis nyob rau hauv tej rooj plaub, e.g., nyob rau hauv hluav taws xob seev, mus txog yim watts), thiab lub sib hloov mus los zaus los ntawm ob txhiab xya pua xya caum-yim txhiab revolutions ib feeb. Txij li thaum lub inrush tam sim no yog me me, thiab lub start-up ntawm kuj tsis yuav tsum tau. Qhov tsawg kawg nkaus naj npawb ntawm cov pins rau lub universal lolus - plaub. Ob tug ntawm lawv yog siv los txuas rau ib tug DC fais fab mov, thiab ob lwm tus - rau AC. Nyob rau hauv lub caij nyoog kawg no cov ntaub ntawv, lub cev muaj zog efficiency yuav txo vim lub high hluav taws xob thiab sib nqus losses. AC yuav haus ntau tshaj li ib tug tsis tu ncua, txij thaum nws yog tsis tsuas active tivthaiv, tab sis kuj reactive.

Muab ceev yuav tswj tau, piv txwv li, ib tug tsis siv transformer los yog ib tug rheostat.

Nrhiav tau sai sai rau qhov tsim nyog mechanism

Nws yog tseeb hais tias muaj ntau qhov chaw nyob qhov twg lub electric tsav yog siv.

195 3730.12.40 - ib tug xov tooj ntawm cov piv txwv rau cov cim ntawm ib tug mechanism, raws li zoo raws li nws loj.

Vim lub fact tias ib tug ntau ua qauv ntawm cov pab kiag li lawm, thiab ib tug ntau yam ntawm ntau thiab tsawg thiab teb ntawm kev siv, koj yuav tsum nrhiav nws yog ib yam nyuaj heev. Qhov no kev faib heev simplifies tus txheej txheem ntawm kev nrhiav ib tug haum hluav taws xob lub cev muaj zog.
