PMDC lub cev muaj zog feem ntau muaj ob ntu. Ib qho armature thiab stator. Lub stator, lub tog raj kheej steel, yog tam sim no. Cov hlau nplaum yog tsau rau sab hauv ntawm lub tog raj kheej lub npoo.
Raws li pom hauv daim duab hauv qab no, cov hlau nplaum ruaj khov tau muab tso ua ke kom txhua tus hlau nplaum N- thiab S-poles hloov mus rau lub ntsej muag. Hauv lwm lo lus, yog tias N-ncej ntawm ib lub hlau nplaum yog tig mus rau lub armature, S-ncej ntawm cov hlau nplaum tom ntej tseem yuav tau ntsib lub armature.
Cov hlau cylindrical stator tuav cov hlau nplaum ntawm nws sab hauv thiab ua raws li qhov tsis muaj zog rov qab rau cov sib nqus flux.
Txawm hais tias lub teb coil tsis tsim nyog rau cov hlau nplaum ruaj khov DC lub cev muaj zog, lawv qee zaum pom los siv ua ke nrog cov hlau nplaum ruaj khov.
Qhov no yog vim qhov tseeb tias qhov kev tawm dag zog los ntawm cov teb coils tuaj yeem them nyiaj rau qhov tsis muaj zog sib nqus hauv cov hlau nplaum ruaj khov. Cov hlau nplaum ruaj khov no feem ntau muaj lub ntiaj teb tsis tshua muaj zog hlau nplaum.
PMDC lub cev muaj zog lub rotor zoo ib yam li lwm cov DC motors. Cov hlau nplaum ruaj khov DC lub cev muaj zog lub rotor lossis armature kuj muaj cov tub ntxhais, windings, thiab commutator. Cov nplooj ntawv hlau uas ua rau lub hauv paus ntawm lub armature yog laminated ua ke nyob rau hauv ib lub voj voog nrog cov slots rau rwb thaiv tsev.
Lub cylindrical slotted armature core yog tsim los ntawm fastening cov ntawv hlau ncig ib zaug. Cov ntawv hlau laminated nrog cov kua roj vanish rwb thaiv tsev yog siv los txo qis eddy tam sim no poob hauv armature ntawm cov hlau nplaum ruaj khov DC motors.
Lub armature conductors yog nyob rau hauv cov qhov ntawm lub armature core lub sab ntug. Armature winding tshwm sim los ntawm kev sib txuas kom raug ntawm armature conductors.
Cov commutator ntu mounted rau ntawm lub cev muaj zog ncej txuas nrog rau qhov kawg terminals ntawm winding. Zoo ib yam li lwm cov DC motors, cov commutator ntu ntawm cov pa roj carbon lossis graphite txhuam yog nias tawm tsam los ntawm lub caij nplooj ntoos hlav los muab tam sim no rau lub armature.
Qhov zoo ntawm PMDC lub cev muaj zog
- Tsis muaj qhov xav tau rau kev teeb tsa kev lom zem.
- Txij li thaum tsis muaj lub zog hluav taws xob xav tau rau kev ua kom muaj zog, DC lub cev muaj zog ua haujlwm tau nce ntxiv.
- Yog tsis muaj teb coil, li no muaj tsawg chav rau lub teb kauj, uas txo lub cev muaj zog tag nrho loj.
- pheej yig dua thiab pheej yig dua rau cov ntawv thov nrog fractional kW kev ntsuas.
Alnico hlau nplaum, Ceramic (ferrite) hlau nplaum, thiab Rare-earth hlau nplaum yog peb hom hlau nplaum ruaj khov ua haujlwm hauv lub cev muaj zog.
1. AlNiCo hlau nplaum
Alnico hlau nplaum muaj qhov muaj qhov seem ntawm qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom. Yog li ntawd, lawv nquag siv nyob rau hauv cov xwm txheej uas tsis tshua muaj tam sim no ntawm lub siab voltage xav tau. Lub cev muaj zog uas muaj peev xwm ua tau los ntawm 1kW txog 150kW ntiav alnico hlau nplaum.
2. Ferrite hlau nplaum
Ferrite hlau nplaum feem ntau tsis tshua kim thiab ua haujlwm hauv PMDC motors rau cov nqi-sensitive daim ntaub ntawv xws li compressors, AC units, thiab freezers.
3. Rov qab lub ntiaj teb hlau nplaum
Lub ntiaj teb hlau nplaum yog tsim los ntawm neodymium-hlau-boron los yog samarium cobalt. Lawv muaj lub siab coercive magnetizing siv thiab siab residual flux. Cov hlau nplaum no tsis raug kev txom nyem demagnetizing teeb meem vim armature tshua.
Cov khoom siv rau lub ntiaj teb cov hlau nplaum feem ntau pheej yig heev. Neodymium hlau boron, uas zoo li muaj peev xwm tiv taus qhov kub thiab txias, tsis tshua muaj nqi hauv cov no dua li samarium cobalt. Rau cov kev siv loj-rhiab, xws li cov tsheb, servo industrial drives, thiab cov motors loj, PMDC motors siv cov hlau nplaum hauv ntiaj teb.
