Classification ntawm DC Motors

Txoj kev Excitation
Txoj kev excitation ntawm DC lub cev muaj zog hais txog yuav ua li cas lub excitation winding yog powered los tsim lub magnetomotive quab yuam thiab tsim lub ntsiab magnetic teb. Raws li kev sib txawv excitation, DC motors tuaj yeem muab faib ua hom hauv qab no:

1. Sib cais Excited DC Tsav
Ib qho tshwj xeeb zoo siab DC lub cev muaj zog yog ib qho uas qhov excitation winding tsis txuas nrog armature winding, tab sis yog siv los ntawm lwm lub zog DC. Cov hlau nplaum tas mus li DC motors kuj tseem tuaj yeem suav tias yog nyias muaj nyias DC motors.

2. Shunt-Wound DC Tsav
Hauv shunt-mob DC lub cev muaj zog, lub excitation winding txuas nrog rau qhov sib npaug nrog lub armature winding. Raws li ib tug shunt generator, lub davhlau ya nyob twg voltage generated los ntawm lub cev muaj zog nws tus kheej powers lub excitation winding; Raws li ib tug shunt lub cev muaj zog, lub excitation winding thiab armature qhia tib lub zog qhov chaw, thiab nyob rau hauv cov nqe lus ntawm kev ua tau zoo, lawv yog tib yam li cais DC motors.

3. Series-Wound DC Tsav
Hauv series -mob DC lub cev muaj zog, qhov kev sib tw winding thiab armature winding tau txuas nrog hauv series thiab tom qab ntawd txuas nrog lub zog DC. Lub excitation tam sim no ntawm hom DC lub cev muaj zog yog tam sim no armature.

4. Compound-mob DC lub cev muaj zog muaj ob txoj hlua khi: lub shunt winding thiab series winding. Yog hais tias lub magnetomotive force (MF) generated los ntawm series winding yog nyob rau hauv tib txoj kev raws li uas generated los ntawm shunt winding, nws yog hu ua cumulative compound excitation. Yog tias ob lub MFs nyob rau hauv cov lus qhia sib txawv, nws yog hu ua qhov sib txawv ntawm qhov sib txawv.

DC motors nrog txawv excitation txoj kev muaj cov yam ntxwv sib txawv. Feem ntau, lub ntsiab excitation txoj kev rau DC motors yog shunt, series, thiab compound excitation, thaum lub ntsiab excitation txoj kev rau DC generators yog cais excitation, shunt, thiab compound excitation.
