Saboda ba zan iya sauya kudaden takamadda na hukuma zuwa ma'aici, regenerative tsirrai zai faru kawai idan takamadda na motor yana fiye da ma'aici. Tushen takamadda na lura a cikin tsirrai ana nuna a graficin. A lokacin da regenerative tsirrai yana faru, yanayi na terminal yana rufe, kuma saboda haka, ake bayar jiki da ake gina waɗannan abubuwan karamin ruwa. Wannan shine ƙarin da ke nufin a yi kawo waɗannan abubuwan karamin ruwa. Saboda haka, da kyau a yi amfani da regenerative tsirrai idan akwai abubuwan karamin ruwa da za su iya gina waɗannan abubuwan karamin ruwa.

Dynamic ko rheostat tsirrai

Dynamic tsirrai shine ɗaya daga cikin tsarin tsirrai na DC motor drives inda kawon armature yana haɗa a yi tsirrai. Wannan tsari shine ɗaya daga cikin manyan hanyoyin da ake amfani a matsayin hukumar DC motor. Idan an bukata in yi tsirrai, za a koye armature na motor daga masu bayar jiki, kuma za a koye kudaden karamin ruwa a kan armature. Saboda haka, motor yana yi aiki a hukuma, kuma karamin ruwa yana haɗa a yi kawo. Tushen hukumar da suka ci gaba da hukumar da suka ci gaba na DC motor ana nuna a cikin hotunan.

Idan an yi kawo bayar jiki, karamin ruwa na armature tana kawo, kuma saboda haka, luran back enf yana rufe, kuma saboda haka, motor yana tsirrai. Don hukumar da suka ci gaba, kawai armature tana kawo don plugging. Tushen hukumar da suka ci gaba da hukumar da suka ci gaba na DC motor ana nuna a cikin hotunan.

Kontrollofwarsa Takamadda

Babban hanyoyin da ake amfani a matsayin hukumar elektroniki suna nufin hukumomin tsirrai na DC motors. Ana sanin tushen da ake amfani don bayyana takamadda na DC motor drives.

Amsa, a cikin wannan tushen, takamadda na motor zai iya kontrollofwarsa kafin da wannan hanyoyin:

Kontrollofwarsa yanayin armature

Daga cikin hanyoyin, kontrollofwarsa yanayin armature shine mafi girma saboda hasken ƙarfi, take da tsari mai zurfi, da kuma take da tsari mai zurfi. Amma, kawai ƙasashe a cikin wannan hanyoyi shine cewa zai iya haɗa a yi kontrollofwarsa kafin da takamadda yana fiye da ma'aici, saboda ba zan iya sauya yanayin armature zuwa ma'aici. Tushen takamadda na lura a cikin kontrollofwarsa yanayin armature ana nuna a cikin hotunan.

Kontrollofwarsa hukuma na flux

Idan an bukata in kontrollofwarsa takamadda zuwa ma'aici, kontrollofwarsa hukuma na flux tana amfani. A lokacin da hukumar da suka ci gaba, za a iya haɗa a yi kontrollofwarsa takamadda zuwa ukuwa da ma'aici, kuma don hukumar da suka ci gaba za a iya haɗa a yi kontrollofwarsa takamadda zuwa sadde da ma'aici. Tushen takamadda na lura a cikin kontrollofwarsa hukuma na flux ana nuna a cikin hotunan.

Kontrollofwarsa kudaden karamin ruwa na armature

Hanyoyin kontrollofwarsa kudaden karamin ruwa tana amfani kudaden karamin ruwa a kan armature, wanda yake sauya karamin ruwa. Wannan hanyoyi ba tashi ba, kuma ba ake amfani ba, kafin da ake bukata in yi kontrollofwarsa takamadda zuwa lokacin daɗi, kamar a cikin hukumar traction.
