Kev sib xyaw
1. Permanent magnet DC lub cev muaj zog:
Nws muaj stator ncej, rotors, txhuam, casings, thiab lwm yam.
Cov stator ncej yog ua los ntawm cov hlau nplaum ruaj khov (cov hlau nplaum tas mus li), ua los ntawm ferrite, alnico, neodymium hlau boron thiab lwm yam ntaub ntawv.Raws li nws cov qauv tsim, nws tuaj yeem muab faib ua ntau hom xws li hom cylindrical thiab hom pobzeb.
Lub rotor feem ntau yog ua los ntawm laminated silicon steel los xij, thiab cov enameled hlau yog qhov txhab ntawm ob lub qhov ntawm lub rotor core (muaj peb windings nyob rau hauv peb qhov), thiab cov pob qij txha yog feem welded rau cov hlau los xij ntawm lub commutator.
Cov txhuam hniav yog ib qho khoom siv hluav taws xob uas txuas cov khoom siv hluav taws xob thiab lub rotor winding, thiab muaj ob lub zog ntawm kev coj ua thiab hnav tsis kam.Cov txhuam hniav ntawm cov hlau nplaum ruaj khov siv cov hlau nplaum ib leeg lossis cov hlau graphite txhuam, thiab cov txhuam hniav electrochemical graphite.
2. Brushless DC lub cev muaj zog:
Nws yog tsim los ntawm cov hlau nplaum ruaj khov rotor, ntau tus ncej winding stator, txoj hauj lwm sensor thiab lwm yam.Lub brushless DC lub cev muaj zog yog tus cwj pwm los ntawm kev tsis muaj txhuam, thiab siv cov khoom siv hluav taws xob hloov hluav taws xob (xws li Hall cov ntsiab lus) kom paub txog kev sib hloov hluav taws xob, uas yog, cov khoom siv hluav taws xob hloov hluav taws xob tau siv los hloov cov khoom siv sib txuas thiab txhuam.Nws muaj qhov zoo ntawm kev ntseeg siab, tsis muaj qhov sib txuas, thiab tsis tshua muaj suab nrov.
Txoj hauj lwm sensor commutates tam sim no ntawm stator winding nyob rau hauv ib tug tej yam kev txiav txim raws li qhov kev hloov ntawm lub rotor txoj hauj lwm (uas yog, nrhiav tau txoj hauj lwm ntawm lub rotor magnetic ncej txheeb ze rau stator winding, thiab generates ib txoj hauj lwm sensing teeb liab ntawm qhov chaw txiav txim. , uas yog ua tiav los ntawm lub teeb liab converter Circuit Court thiab ces tshem tawm.Control lub hwj chim hloov circuit, thiab hloov lub winding tam sim no raws li ib tug tej yam logic kev sib raug zoo).

Txoj hauj lwm sensor commutates tam sim no ntawm stator winding nyob rau hauv ib tug tej yam kev txiav txim raws li qhov kev hloov ntawm lub rotor txoj hauj lwm (uas yog, nrhiav tau txoj hauj lwm ntawm lub rotor magnetic ncej txheeb ze rau stator winding, thiab generates ib txoj hauj lwm sensing teeb liab ntawm qhov chaw txiav txim. , uas yog ua tiav los ntawm lub teeb liab converter Circuit Court thiab ces tshem tawm.Control lub hwj chim hloov circuit, thiab hloov lub winding tam sim no raws li ib tug tej yam logic kev sib raug zoo).
3. Kev kub ceev ruaj khov hlau nplaum brushless lub cev muaj zog:
Nws yog tsim los ntawm stator core, magnetic steel rotor, hnub iav, deceleration clutch, hub plhaub thiab lwm yam.Lub Hall sensor tuaj yeem ntsia tau rau ntawm lub hau npog rau kev ntsuas ceev.
Kev sib piv ntawm brushed motors thiab brushless motors
Qhov sib txawv ntawm lub hauv paus ntsiab lus ntawm kev siv hluav taws xob ntawm lub cev muaj zog thiab lub cev tsis muaj lub cev muaj zog: Lub cev muaj zog brushed yog mechanically commutated los ntawm ib tug txhuam hniav thiab ib tug commutator.Lub cev muaj zog brushless yog hluav taws xob hloov pauv los ntawm tus maub los raws li lub teeb liab induction
Lub hauv paus ntsiab lus ntawm lub hwj chim ntawm lub cev muaj zog thiab lub cev tsis muaj zog yog qhov sib txawv, thiab nws cov qauv sab hauv kuj txawv.Rau hub motors, cov zis hom ntawm lub cev muaj zog torque (txawm nws yog decelerated los ntawm lub iav txo mechanism) yog txawv, thiab nws mechanical qauv kuj txawv.
