DC Motor Performance
Dec 16, 2025
Kev ua tau zoo ntawm DC lub cev muaj zog muaj feem cuam tshuam nrog nws txoj kev excitation. Feem ntau muaj plaub hom excitation txoj kev rau DC motors: cais DC motors, DC shunt motors, DC series motors, thiab DC compound motors. Kev nkag siab txog cov yam ntxwv ntawm txhua txoj kev yog qhov tseem ceeb:
1. Sib cais DC Tsav: Lub teb winding tsis yog hluav taws xob txuas nrog armature; lub excitation Circuit Court yog muab los ntawm ib tug cais DC fais fab mov. Yog li ntawd, lub excitation tam sim no tsis cuam tshuam los ntawm armature davhlau ya nyob twg voltage los yog armature tam sim no.
2. Shunt DC Tsav: Lub voj voog yog sib npaug, ua rau kev faib tam sim no. Qhov voltage hla lub shunt winding yog tib yam li armature voltage. Txawm li cas los xij, lub teb winding yog ua los ntawm nyias hlau nrog ntau lem, ua rau muaj kev tiv thaiv tseem ceeb thiab me me excitation tam sim no.
3. DC Series Tsav: Tam sim no txuas nrog hauv series, ua rau muaj kev faib hluav taws xob. Lub teb winding yog txuas nrog nyob rau hauv series nrog armature, yog li lub magnetic teb nyob rau hauv lub hom ntawm lub cev muaj zog hloov ho nrog kev hloov nyob rau hauv armature tam sim no. Yuav kom txo qis qhov poob thiab qhov hluav taws xob poob hauv qhov excitation winding, nws qhov tsis kam yuav tsum tsawg li tsawg tau. Yog li, DC series motors feem ntau raug mob nrog cov xov hlau tuab thiab muaj tsawg dua.
4. DC compound lub cev muaj zog: Cov sib nqus flux ntawm lub cev muaj zog yog tsim los ntawm kev ua haujlwm tam sim no hauv ob qho tib si windings.
