Abubuwa na DC Generators
Muhimmiya Turuwa da DC Generator
DC Generator da Alama Maimakawa – Aikin maimakawa suna amfani da alama mai zurfi
DC Generator da Amfani da Tsari Mai Zurfi – Aikin maimakawa suna amfani da tsari mai zurfi na waje
DC Generator da Yake Amfani da Tsari – Aikin maimakawa suna amfani da tsari na generator tare
DC Generator da Yake Amfani da Tsari
DC generator da yake amfani da tsari yana amfani da fitarwa ta da yake don kula aikin maimakawa, wanda zai iya kasance da shi a kan wurin series, shunt, ko compound wound.
Na biyu sunan turuwa da suka da DC generator da yake amfani da tsari su ne:
Series Wound Generators
Shunt Wound Generators
Compound Wound Generators
DC Generator da Alama Maimakawa
Idan flux a cikin ci gaba mai zurfi yana faruwa ne da amfani da alama maimakawa, ana kiranta ake kira DC generator da alama maimakawa.
Yana da armature da kuma alama maimakawa kadan ko kafuwa a kan armature. Wannan irin DC generator ba take faruwa da abubuwan kayan aiki bacewa. Saboda haka ba a lura a fannin aiki masu kayayyaki. Suna amfani da su a fannin aiki mai kuda – kamar dinamo a motosikilu.
DC Generator da Amfani da Tsari Mai Zurfi
Wadannan su ne generators da aikin maimakawarsu suna amfani da tsari mai zurfi na waje, kamar battery.
A diagram ta circuit ta DC generator da amfani da tsari mai zurfi an samu a nan. Alamun da ake amfani su ne:
Ia = Armature current
IL = Load current
V = Terminal voltage
Eg = Generated EMF (Electromagnetic Force)
DC Generators da Yake Amfani da Tsari
DC Generators da Yake Amfani da Tsari: Wadannan generators suna amfani da fitarwa ta da yake don kula aikin maimakawa. Aikin maimakawa a wasu masu aiki suke danganta da armature.
Saboda residual magnetism, akwai flux da yake cika a cikin poles. Idan armature ya kara, za a faruwa EMF. Saboda haka za a faruwa current. Wannan current mai karamin ya koma a cikin aikin maimakawa da kuma load, kuma yana tabbatar da flux na pole.
Idan flux na pole ya tabbatar, yana faruwa da armature EMF, wanda yake sa current na field zuwa rike. Wannan field current na rike yana faruwa da armature EMF, kuma wannan fenomenon na cumulative yana ci gaba har zuwa idan excitation ya karkashin rated value.
Idan lokacin aikin maimakawa, DC generators da yake amfani da tsari zai iya kira:
Series Wound Generators
Shunt Wound Generators
Compound Wound Generators
Series Wound Generator
A cikin wannan haɗin, aikin maimakawa suna danganta da armature conductors a kan series, wanda yake tabbatar da flow of electricity throughout the generator.
Current duka yana koma a cikin aikin maimakawa da kuma load. Saboda series field winding ya kasa full load current, an yi da ita da few turns of thick wire. The electrical resistance of series field winding is therefore very low (nearly 0.5Ω).
Hakan:
Rsc = Series winding resistance
Isc = Current flowing through the series field
Ra = Armature resistance
Ia = Armature current
IL = Load current
V = Terminal voltage
Eg = Generated EMF
Long Shunt Compound Wound DC Generator
Long Shunt Compound Wound DC Generator su ne generators da aikin maimakawa shunt yana danganta da series field da armature winding, kamar yadda ake bayyana a nan.
Compound Wound Dynamics
A cikin generators, predominant shunt field an tabbatar da series field, wanda yake kira cumulative compound configuration.
Duk da haka, idan series field ya kusa shunt field, ana kiranta ake kira differentially compound wound.
