Gagare Armature

Takaitaccen kudin armature

Kudin armature a wata alternator yana nuna takaitar kudin ciki don gina elektrik da ke muhimmanci ga tattalin aiki.

Na'urar kudin armature

Kudin armature mai tsawo taɗe

Kudin armature mai tsawo taɗe zai iya kasance centralized ko distributed.

Kudin armature centralized

Idan adadin slots a armature yana daga cikin machine yana iya duba adadin poles, ana amfani da kudin centralized. Na'urar kudin yana ba da fadada voltage mafi yawa, amma ba a tabbas sinusoidal. Kudin tsawo taɗe mafi so kuɗi a nan ya fi shahara a Figure 1 da aka bayyana. Haka, adadin poles = adadin slots = adadin sides of coils. Haka, side of coil wata yana cikin slot wata ta pole wata da side of coil na biyu yana cikin slot na biyu ta pole na biyu. Electromotive force inda a side of coil wata zai zama da electromotive force a side of coil na biyu.

Kudin armature distributed

Don samun electromotive force wave mai tsawon sinusoidal, ana koyar conductors a slots da dama ta unipole. Na'urar kudin armature wanda aka sani shine kudin distributed. Idan kudin armature distributed a wata alternator yana rage electromotive force, amma yana da muhimmanci ga wasu dalilai.

• Yana iya rage harmonic electromotive force, don haka ya ba da lada waveform.

• Yana rage armature reactions.

• Conductors da suka faɗa suna taimaka waƙoƙi masu ingantacce.

• Saboda conductors suka faɗa a slots a periphery of the armature, magnetic core an amfani da shi daidai.

Kudin lap a alternator

Kudin lap mai tsawo taɗe 4-pole, 12-slot, 12-conductor (conductor wata a slot) full-pitch lap winding a wata alternator an bayyana a nan.

Back pitch of the winding yana da adadin conductors per pole, yana da ma'anin = 3, and front pitch yana da ma'anin back pitch minus 1.

Kudin wave a alternator

Kudin wave mai tsawo taɗe 4-pole, 12-slot, 12-conductor, an bayyana a Figure e a nan. Haka, both back and front spacing yana da ma'anin adadin conductors per pole.

Kudin armature polyphase

An amfani da shi a polyphase alternators don bincike performance mai tsawo da gina elektrik daidai a kan phases da dama.
