Wani ya ƙarfi na mota na DC?

Zai ya cewa na Muhimmiyar Gwamnati na Motor DC?

Takardun Muhimmiya

Muhimmiya a motor DC yana nufin ziyartar karamin kasa ko gudanar mutanen kasa.

Idan wani yanayi da ake amfani da shi a matsayin motor ko generator, zaɓuɓɓuka suka ɗauki abubuwa. Waɗannan zaɓuɓɓukan ke cikin faruwar magana ta hanyar rukunin sassa.

Saboda haka, kowane zaɓuɓɓukan ke samu ziyarta. Zaɓuɓɓukan ke cikin fadada rotor a tarihi daidai daga murabba. Saboda haka, muhimmiya ta fito a tsakiyar rotor da rotor ya bazu zuwa kasa. Dr. Huge d Young ya bayyana muhimmiya a kan yadda ziyarta ta iya zama alamar karamin kasa, ko kuma yi gudanar mutanen kasa. Wannan ita ce mafi alamar ziyarta wanda ta iya zama karamin kasa ko kuma yi gudanar mutanen kasa.

Takarda na muhimmiya yana ba da,

Amsa, F shine ziyarta a hanyar dogon ziyarta.

R shine rukunin abincin da ake kashe,

da θ shine ziyarta, ziyarta F ta shiga da R vector

Motor DC shine karfi mai kasa inda muhimmiya ce mafi muhimmanci. Yadda ake fahimtar takarda na muhimmiya na motor DC yana da muhimmanci don tabbatar da manyan al'amuran da ake yi game da shi.

Don a tabbatar da takarda na muhimmiya, za a duba takarda na voltage na motor DC da kuma takarda na voltage.A taka wannan rubutu, za a iya gano, idan E shine voltage na supply, Eb shine back emf da aka bayar da Ia, Ra su ne armature current da kuma armature resistance maka takarda na voltage yana ba da,

Don a tabbatar da takarda na muhimmiya na motor DC, za a faɗi kowane pata na takarda na voltage da Ia.

Na Ia2.Ra shine karkashin power da ya faru saboda haɗaɗin armature coil, da kuma babban mechanical power da ya fi kyau don a yi muhimmiyar da ake buƙaci a motor DC yana ba da,

Power mai karfi Pm ana girma da electromagnetic torque Tg a kan,

Amsa, ω shine speed a rad/sec.

Daga baya, a bar da equation (4) da (5) za a samu,

Daga baya, don a sauransu takarda na muhimmiya na motor DC za a gaba da.

Amsa, P shine number of poles,

φ shine flux per pole,

Z shine number of conductors,

A shine number of parallel paths,

da N shine speed of the DC motor.

Bar da equation (6) da (7) a equation (4), za a samu:

Wannan muhimmiya da aka samu an sanar da electromagnetic torque na motor DC. Idan a doke mechanical and rotational losses, za a samu mechanical torque.

Saboda haka,

Wannan shine takarda na muhimmiya na motor DC. Ana iya sauransu a haka:

Wannan shine constant for a particular machine and therefore the torque of DC motor varies with only flux φ and armature current I a.

Takarda na muhimmiya na motor DC ina iya bayyana a cikin rubutun da ake ɗauki a baya

Current/conductor I c = Ia A

Saboda haka, force per conductor = fc = BLIa/A

Daga baya, torque Tc = fc. r = BLIa.r/A

Saboda haka, total torque developed of a DC machine is,

Wannan takarda na muhimmiya na motor DC ina iya sauransu a haka:

Wannan shine constant for a particular machine and therefore the torque of DC motor varies with only flux φ and armature current I a.
