Q: Dab tsi yog magnetic motors siv rau?

A: Cov hlau nplaum tas mus li yog siv nyob rau hauv ntau yam khoom siv niaj hnub, xws li cov txhuam hniav hluav taws xob. Nyob rau hauv sib piv rau cov uas tsis yog-existent sib nqus lub cev muaj zog tsuas yog piav qhia, uas yuav siv tau los tsim lub zog los yog hluav taws xob, lawv ua hauj lwm zoo ib yam li AC lub cev muaj zog - nrog kev pab los ntawm electromagnetism.

Q: Dab tsi yog cov rotors siv hauv centrifugation?

A: Centrifuge Rotor Hom
Ob lub ntsiab ntawm cov rotors siv nyob rau hauv chav kuaj centrifuges yog kab rov tav (tseem hu ua viav vias thoob) thiab lub kaum sab xis (los yog lub taub hau lub taub hau) rotors.

Q: Peb daim ntawv thov ntawm cov nyhuv sib nqus yog dab tsi?

A: Cov nyhuv sib nqus ntawm cov tam sim no yog siv rau hauv cov khoom siv xws li hluav taws xob motors, generators, transformers, thiab magnetic resonance imaging (MRI) machines. Cov nyhuv sib nqus ntawm tam sim no, tseem hu ua electromagnetism, yog lub hauv paus ntsiab lus tseem ceeb uas txhawb nqa ntau cov thev naus laus zis niaj hnub no.

Q: Dab tsi yog ob hom rotors pom nyob rau hauv induction motors?

A: Induction motor rotors yuav yog ob hom, qhov txhab rotor lossis squirrel-cage rotor. Lub qhov txhab rotor muaj windings zoo ib yam li thiab qhov txhab rau tib tus naj npawb ntawm tus ncej raws li tus stator. Lub rotor windings yog txuas nrog insulated slip rings mounted ntawm lub rotor ncej.

Q: Dab tsi lub cev muaj zog muaj hlau nplaum ruaj khov rotor?

A: IPM motors muaj cov hlau nplaum ruaj khov rau hauv lub rotor nws tus kheej. Tsis zoo li lawv cov SPM counterparts, qhov chaw ntawm cov hlau nplaum tas mus li ua rau IPM motors zoo heev, thiab tsim nyog rau kev khiav hauj lwm ntawm qhov ceev heev.

Q: Lub tshuab hluav taws xob puas tuaj yeem khiav ntawm AC?

A: Cov hlau nplaum ruaj khov AC lub cev muaj zog (PMAC) zoo ib yam li tus qauv induction AC motors tshwj tsis yog lawv muaj cov hlau nplaum ruaj khov, tsis tshua muaj ntiaj teb txuas rau lawv cov rotors (qhov nruab nrab ntawm lub cev muaj zog uas tig). Muaj cov hlau nplaum tas mus li es tsis txhob siv electromagnets txo lub zog poob hauv lub cev muaj zog.

Q: Dab tsi yog 2 hom rotors sib txawv thiab qhov txawv ntawm lawv?

A: Plain rotors yog du nrog tsis muaj qhov lossis qhov thiab saib yooj yim. Drilled rotors muaj qhov uas pab dej & cua sov dissipate thiab saib txias. Slotted rotors muaj qhov tso cai rau cov pa roj & plua plav kom khiav thiab saib txias.

Q: Hom rotors ntev npaum li cas?

A: Feem ntau, cov rotor dawb paug / du yuav muaj lub neej ntev dua li cov drilled lossis slotted rotors vim lawv qhov chaw loj dua thiab tsis muaj kev ntxhov siab. Drilled rotors, ntawm qhov tod tes, muaj ntau dua rau kev tawg nyob rau hauv kev ntxhov siab heev, uas yuav ua rau lawv lub neej luv.

Q: Dab tsi yog qhov zoo tshaj plaws hlau siv los ua hlau nplaum?

A: Tsuas yog cov ntaub ntawv ferromagnetic xws li hlau, cobalt, thiab npib tsib xee yog nyiam rau cov hlau nplaum muaj zog txaus los txiav txim siab sib nqus.

Q: Koj ua li cas thiaj li ua hluav taws xob nrog cov hlau nplaum?

A: Sib nqus teb tuaj yeem siv los ua hluav taws xob
Tsiv cov hlau nplaum nyob ib ncig ntawm ib lub kauj ntawm cov hlau, los yog txav ib lub kauj ntawm cov hlau nyob ib ncig ntawm cov hlau nplaum, thawb cov electrons hauv cov hlau thiab tsim cov hluav taws xob tam sim no. Cov tshuab hluav taws xob tseem ceeb hloov lub zog kinetic (lub zog ntawm kev txav) mus rau hauv hluav taws xob.
