Switched Reluctance Motor Magnets

Lub cev muaj zog hloov pauv yog ib hom tshwj xeeb ntawm lub cev muaj zog uas nws lub rotor muaj ntau tus ncej, txhua tus ncej khub muaj cov hlau nplaum thiab tsis kam lees. Switched reluctance motors feem ntau yog siv nyob rau hauv daim ntawv thov uas yuav tsum tau siab pib torque thiab high efficiency, xws li hluav taws xob tsheb thiab industrial drives.

Hauv lub cev hloov pauv tsis txaus ntseeg, cov hlau nplaum feem ntau yog cov hlau nplaum ruaj khov thiab siv los tsim cov hlau nplaum ruaj khov. Magneto-resistors yog ua los ntawm cov khoom sib nqus uas tswj tau los ntawm cov hluav taws xob tam sim no los kho lub zog thiab kev taw qhia ntawm cov hlau nplaum. Thaum tam sim no dhau los ntawm kev tsis txaus siab, cov hlau nplaum ntawm qhov tsis txaus siab nce, tsim kom muaj zog hlau nplaum uas nyiam cov hlau nplaum rau qhov tsis txaus ntseeg nyob ib sab ntawm nws. Cov txheej txheem no ua rau lub rotor tig, uas ua rau lub cev muaj zog.

Cov hlau nplaum ua lub luag haujlwm hauv kev tsim cov hlau nplaum mus tas li nyob rau hauv qhov hloov pauv tsis kam lub cev muaj zog, thiab qhov tsis kam kho lub zog thiab kev taw qhia ntawm cov hlau nplaum los tswj kev ua haujlwm ntawm lub cev muaj zog.

Basic ua hauj lwm hauv paus ntsiab lus ntawm switched reluctance motor

Lub tshuab hluav taws xob hloov pauv (Switched Reluctance Motor, SRM) ntawm lub tsheb hluav taws xob muaj cov qauv yooj yim. Lub stator tau txais cov qauv kev sib xyaw ua ke, thaum lub rotor tsis muaj winding. Cov qauv ntawm kev hloov pauv tsis kam lub cev muaj zog thiab lub induction stepping lub cev muaj zog yog qhov zoo sib xws, thiab ob qho tib si siv lub zog sib nqus (Max-zoo quab yuam) ntawm cov xov xwm sib txawv nyob rau hauv qhov kev txiav txim ntawm magnetic teb los tsim electromagnetic torque.

Lub stator thiab rotor ntawm lub hloov tsis kam lub cev muaj zog yog tsim los ntawm silicon steel ntawv laminations thiab txais yuav cov qauv zoo nkauj. Lub stator thiab rotor ncej ntawm lub hloov tsis kam lub cev muaj zog sib txawv, thiab ob qho tib si stator thiab rotor muaj me me cogging. Lub rotor yog tsim los ntawm high-magnetic hlau core yam tsis muaj coils. Feem ntau, lub rotor muaj ob tug ncej tsawg dua stator. Muaj ntau qhov sib xyaw ua ke ntawm stators thiab rotors, feem ntau yog cov qauv ntawm rau stators thiab plaub rotors (6/4) thiab cov qauv ntawm yim stators thiab rau rotors (8/6).

Switched reluctance lub cev muaj zog yog ib hom kev ceev tswj lub cev muaj zog tsim tom qab DC lub cev muaj zog thiab brushless DC lub cev muaj zog (BLDC). Lub hwj chim theem ntawm cov khoom muaj xws li los ntawm ob peb watts mus rau pua pua ntawm kw, thiab yog dav siv nyob rau hauv lub teb ntawm cov khoom siv hauv tsev, aviation, aerospace, electronics, machinery thiab hluav taws xob tsheb.

Nws ua raws li lub hauv paus ntsiab lus hais tias lub magnetic flux yog ib txwm kaw nyob rau hauv txoj kev nrog lub loj tshaj plaws magnetic permeability, thiab generates magnetic rub quab yuam los tsim ib tug torque-reluctance electromagnetic torque. Yog li ntawd, nws lub hauv paus ntsiab lus yog qhov tsis kam ntawm cov hlau nplaum Circuit Court yuav tsum hloov ntau npaum li sai tau thaum lub rotor rotates, yog li lub switched reluctance lub cev muaj zog txais ib tug ob salient ncej qauv, thiab tus naj npawb ntawm tus ncej ntawm stator thiab rotor yog txawv.

Lub controllable switching Circuit Court yog lub converter, uas ua rau lub ntsiab fais fab Circuit Court ua ke nrog lub hwj chim mov thiab lub cev muaj zog winding. Qhov chaw ntes tau yog ib qho tseem ceeb ntawm cov yam ntxwv ntawm lub cev hloov pauv tsis txaus siab. Nws pom qhov chaw ntawm lub rotor hauv lub sijhawm tiag tiag thiab tswj kev ua haujlwm ntawm lub converter kom zoo thiab ua tau zoo.

Lub cev muaj zog pib loj, me me pib tam sim no, siab zog ceev thiab torque inertia piv, ceev ceev dynamic teb, high efficiency nyob rau hauv ib tug dav ceev ntau yam, thiab tau yooj yim paub plaub-quadrant tswj. Cov yam ntxwv no ua rau lub cev hloov pauv tsis txaus siab heev rau kev ua haujlwm nyob rau hauv ntau yam kev ua haujlwm ntawm lub tsheb hluav taws xob, thiab nws yog ib qho qauv uas muaj peev xwm zoo ntawm cov tsheb fais fab. Lub cev hloov pauv tsis kam tsav lub cev muaj zog siv cov khoom siv hlau nplaum ua haujlwm zoo rau lub cev hloov lub cev tsis txaus siab, uas yog kev txhim kho muaj zog rau lub cev muaj zog. Lub cev muaj zog yog li kov yeej qhov tsis txaus ntawm kev sib hloov qeeb thiab kev siv hluav taws xob tsawg hauv cov tsoos SRMs, thiab ua rau kom muaj zog tshwj xeeb ntawm lub cev muaj zog. Lub cev muaj zog muaj lub zog loj, uas muaj txiaj ntsig zoo rau nws daim ntawv thov hauv tsheb hluav taws xob.
