Dab tsi yog qhov ua rau lub nplhaib hluav taws kub hauv DC motors?

Thaum lub DC lub cev muaj zog khiav, muaj zog arc tshwm nyob ib ncig ntawm lub commutator nto, uas yog qhov hu ua "ring fire" tshwm sim. Dab tsi yog qhov ua rau DC motor ringfire? Cov lus teb hauv qab no rau koj
(1) Lub commutator inter-piece voltage siab dhau lawm, ua rau lub cev muaj zog khiav dhau-voltage, thiab ces commutator inter-piece tawg thiab ringfire yuav tshwm sim.

(2) vim kev saib xyuas tsis zoo ntawm commutator, tu tsis loj, commutator mica groove nyob rau hauv tsub zuj zuj ntawm carbon hmoov thiab tooj liab hmoov, los yog vim tus choj nyem tooj liab, commutator tooj liab burr extension ua rau nyob ib sab commutator luv luv Circuit Court, cov conductive tshuaj yog tsim los ntawm tus choj conductive hauv mica groove.

(3) ua rau commutator tsim lub nplhaib hluav taws kub lwm yam tseem ceeb yog txhuam sparks, thaum lub DC lub cev muaj zog ua hauj lwm nyob rau hauv tsis tshua muaj hnyav load tej yam kev mob, commutator nto zawv zawg, hu rau kev puas tsuaj loj, txhuam thiab commutator yuav ua rau muaj teeb meem loj ntawm.
Cov saum toj no yog los qhia koj txog qhov ua rau DC lub nplhaib hluav taws kub tshwm sim, cov ntaub ntawv ntau ntxiv txog cov ntaub ntawv ntsig txog lub cev muaj zog txais tos hu rau peb txhua lub sijhawm
