LED vaj huam sib luag teeb feem ntau yog tsim los ntawm DC lub cev muaj zog, lub tshuab xa hluav taws xob thiab lub tshuab hluav taws xob hloov hluav taws xob.
1. DC lub cev muaj zog kev tsim kho
DC lub cev muaj zog yog tsim los ntawm ib qho armature, ib tug hlau nplaum, ib lub casing, txhuam thiab txhuam tuav.
(1) Armature los ua ke Lub armature yog siv los tsim hluav taws xob torque, uas yog tsim los ntawm cov tub ntxhais, ib qho armature winding, armature ncej thiab commutator. Lub armature tub ntxhais yog tsim los ntawm stacking ib tug ntau ntawm kev sib nrig sib insulated silicon steel nplooj ntawv; lub armature winding yog mob los ntawm ib tug tuab tooj liab ca hlau los ntawm ib tug yoj winding txoj kev; tooj liab ntawm lub commutator yog tuab, thiab mica yog siv los ntawm cov ntawv tooj liab uas nyob ib sab. Daim ntawv rwb thaiv tsev.
2. Magnetic ncej
Cov ncej hlau nplaum yog tsim los ntawm ib qho tseem ceeb thiab kev zoo siab winding, thiab nws txoj haujlwm yog tsim kom muaj cov hlau nplaum hauv lub cev muaj zog. Cov ncej ncej feem ntau yog ua los ntawm cov hlau tsis tshua muaj carbon steel thiab tsau rau lub cev muaj zog los ntawm cov ntsia hlau. Cov ncej hlau nplaum feem ntau yog plaub, thiab ob khub ntawm cov ncej hlau nplaum tsim ob khub ntawm cov ncej sib nqus, uas yog qhov sib txawv. Ib qho excitation winding feem ntau txuas nrog hauv cov khoom siv armature winding, yog li nws yog hu ua series-excited direct tam sim no lub cev muaj zog.
3. Txhuam thiab txhuam tuav
Kev ua haujlwm ntawm tus txhuam hniav thiab tus txhuam hniav yog los qhia tam sim no rau hauv armature kom lub armature tig tsis tu ncua. Txhuam yog feem ntau nias nrog tooj liab thiab graphite los pab txo cov hluav taws xob tiv thaiv thiab ua kom hnav tsis kam. Cov txhuam yog mounted nyob rau hauv tus txhuam tuav thiab nias tawm tsam lub commutator los ntawm lub caij nplooj ntoos hlav siab. Txuas ncaj qha mus rau sab nrauv los tsim ib lub voj voog hauv av, hu ua av txhuam, txuas nrog rau qhov excitation winding thiab armature winding, thiab insulated los ntawm cov txheej sab nrauv, hu ua insulated txhuam.
4. Plhaub
Lub casing txheej yog dov los ntawm cov pa roj carbon tsawg los yog cam khwb cia hlau cam khwb cia hlau. Lub sij hawm pib ntawm lub starter yog luv heev, yog li zawv zawg bearings feem ntau yog siv. Lub deceleration oob khab siv lub dov bearing vim lub siab rotational ceev ntawm nws armature.
