Yadda yana ɗauke masu zuba na gincin karkashin wata da kuma maimakon sama?
A wata da karamin koyar da karkashin kashi ko mai sarrafa (ya'ni karamin koyar) zai iya haɗa da tasirin mafi yawa a cikin faduwar volts. Haka ne suka yi da tarihin hankali:
Tasiri a cikin kashi
Sana'a
Kashi ta yi aiki a cikin sana'a da take da shi a kan electromagnetic induction, domin Faraday's law of electromagnetic induction, idan mai zurfi ya gaba magana mai koyar, za a samun electromotive force (EMF) a cikin mai zurfi. Tsawon electromotive force shine mutane da ke tsawo a kan tsawon da ake gaba magana mai koyar da karamin koyar a cikin mai zurfi.
E=N⋅A⋅B⋅v
Daga cikinsu:
E shine electromotive force (voltage) da aka samu;
N shine karamin koyar;
A shine tsakiyar da na koyar;
B shine tsayi da take da magnetic field;
v shine rarrabe da ake gaba magana mai koyar.
Tasiri
Zamani volt
A yi karamin koyar zai haɗa da electromotive force, ya'ni faduwar volts daga kashi zai zamani. Wannan shine saboda karamin koyar masu yawa suna amfani da electromotive force masu yawa a lokacin da ake gaba magana mai koyar.
Idan wasu abubuwa (kamar tsayin magnetic field, rarrabe da ake gaba magana, etc.) ba suka badala, a yi karamin koyar zai haɗa da zamani a voltage.
Zamani magnetic field
A yi karamin koyar zai haɗa da zamani a magnetic field, saboda karamin koyar masu yawa suna amfani da magnetic field masu yawa. Wannan zai haɗa da zamani a electromotive force.
Sana'o'i da cost
A yi karamin koyar zai haɗa da zamani a sana'o'i da kashi, wanda zai haɗa da sana'o'in aiki. A nan a cost, karamin koyar masu yawa suna haɗa da cost masu yawa a gudanar da aiki.
Tasiri a cikin motor
Sana'a
Electric motor ta yi aiki a cikin sana'a da take da shi a kan electromagnetic induction, amma ta yi aiki a cikin yanayi da kashi: energy electric input ta zama energy mechanical. Current a motor ta gudu a koyar don haɗa da magnetic field, wanda ta haɗa da magnetic field da aka fara a kan permanent magnet ko koyar masu yawa don haɗa da torque wanda ta haɗa da rotor a motor zuwa rotation.
Tasiri
Zamani magnetic flux density
A yi karamin koyar zai haɗa da zamani a magnetic field da current ta haɗa, wanda zai haɗa da zamani a flux density a cikin motor.
Magnetic field masu yawa zai haɗa da torque masu yawa, wanda zai haɗa da output power a motor.
Ingantaccen voltage da current
A yi karamin koyar zai haɗa da zamani a back EMF a motor, wanda shine electromotive force da aka samu a koyar a lokacin da motor ta zo.
Zamani a back electromotive force zai haɗa da ci gaba a requirements da motor ta buƙaci, wanda zai haɗa da ci gaba a heat da loss a motor.
Efficiency da performance
A yi karamin koyar zai haɗa da efficiency a motor, saboda magnetic field masu yawa da torque masu yawa zai haɗa da ci gaba a losses da current.Amma, karamin koyar masu yawa zai haɗa da inertia masu yawa a motor, wanda zai haɗa da response speed.
Sana'o'i da cost
A yi karamin koyar zai haɗa da zamani a sana'o'i da kashi, wanda zai haɗa da sana'o'in aiki. A nan a cost, karamin koyar masu yawa suna haɗa da cost masu yawa a gudanar da aiki.
Gajarta
A yi karamin koyar a cikin kashi ko motor zai haɗa da tasirin mafi yawa a cikin faduwar volts ko magnetic flux density. A cikin kashi, a yi karamin koyar zai haɗa da zamani a output voltage; A cikin electric motors, a yi karamin koyar zai haɗa da zamani a magnetic flux density, wanda zai haɗa da torque da efficiency. Amma, wannan zai haɗa da sana'o'i da cost. A cikin applications masu yawa, improvements in performance zai haɗa da ci gaban factors kamar cost da size.
