Dab tsi yog cov yam ntxwv ntawm micro DC lub cev muaj zog? Ntau hom DC lub cev muaj zog yog siv ntau yam khoom siv hluav taws xob, thiab cov yam ntxwv ntawm ntau hom DC motors txawv. Hauv qab no yog cov lus piav qhia luv luv.
Cov qauv yooj yim ntawm cov me me DC lub cev muaj zog yog tsim los ntawm cov hlau nplaum ruaj khov, cov tub ntxhais hlau coils, txhuam hniav, thiab cov commutators. Cov zis torque yog generated los ntawm electromagnetic quab yuam ntawm cov hlau nplaum tas mus li flux thiab armature tam sim no. Cov hlau nplaum tas mus li yog lub stator, lub kauj yog lub rotor, thiab cov hluav taws xob Cov txhuam hniav hla qhov tam sim no los ntawm lub kauj, thiab lub commutator ua kom cov zis tawm mus tas li.
Basic formula ntawm micro DC motor yam ntxwv
DC motor davhlau ya nyob twg voltage=rov qab EMF + armature coil reactance txhuam kev tiv thaiv thiab armature tam sim no, rov qab EMF thiab torque tuaj yeem xam los ntawm cov hauv qab no:
1. Rov qab EMF=K1 (proportional constant) n (ceev) Φ (magnetic flux)
2. Torque=K2 (proportional constant) Φ (magnetic flux) Ia (armature tam sim no)
