Muhimmanci Bincike na Armature Winding

 Takardun Pole Pitch

Pole pitch yana nufin darajar da ke cikin mafi girman shugaban duwatsuwa a kan tafkin masu shugaba mai sani a cikin mutanen DC. Wannan darajin ya kira a cikin tafukar armature ko kuma masu shugabanci a cikin armature da ke cikin tafkin masu shugaba mai sani.

Pole pitch yana iya zama jami'ar tafukar armature zuwa jami'ar tafukar masu shugabanci a cikin mutanen.

Misali, idan akwai 96 tafukar armature a tafkin masu shugabanci da 4 tafukar masu shugabanci, jami'ar tafukar armature da ke cikin tafkin masu shugaba mai sani yana iya zama 96/4 = 24. Saboda haka, pole pitch na wannan mutanen DC yana zama 24.

Saboda pole pitch yana iya zama jami'ar tafukar armature zuwa jami'ar tafukar masu shugabanci, ake amfani da ita a matsayin tafukar armature da ke cikin tafukar masu shugabanci.

Takardun Coil Span

Coil span (ko kuma coil pitch) yana nufin darajar da ke cikin tafkin masu shugabanci a kan tafkin masu shugabanci, ya kira a cikin tafukar armature da ke cikin tafkin masu shugabanci. Yana bayyana cewa tafukar masu shugabanci suka yi a cikin tafkin masu shugabanci.

Idan coil span yana iya zama pole pitch, ake cewa armature winding yana iya zama full-pitched. A cikin wannan yanayi, tafukar masu shugabanci mai suna suka yi a cikin tafukar masu shugabanci mai suna.

 Saboda haka, EMF da ake fara a tafkin masu shugabanci mai suna yana iya zama 180o phase shift da EMF da ake fara a tafkin masu shugabanci mai suna. Saboda haka, terminal voltage na yawan masu shugabanci yana iya zama arithmetic sum daga waɗannan EMF biyu.

Idan coil span yana iya zama lashe da pole pitch, ake cewa winding yana iya zama fractional pitched. A cikin wannan masu shugabanci, za a samun farkon EMFs a kan tafkin masu shugabanci mai suna, lashe da 180o. Saboda haka, terminal voltage na yawan masu shugabanci yana iya zama vector sum daga waɗannan EMF biyu, kuma yana iya zama lashe da full-pitched coil.

A fice, ana amfani da coil span da yake zama eight-tenths of a pole pitch bace ta ba sa shawarar EMF ba. Ana amfani da fractional-pitched windings don in inganta copper a end connections da kuma in gane commutation.

Full-Pitched Winding

Full-pitched winding yana iya zama coil span da yake iya zama pole pitch, wanda ya farawa EMFs da suka zama 180 degrees out of phase, summing directly.

Fractional-Pitched Winding

Fractional-pitched winding yana iya zama coil span da yake lashe da pole pitch, wanda ya farawa phase difference da yake lashe da 180 degrees da kuma vector sum of EMFs.

Takardun Commutator Pitch

Commutator pitch yana nufin darajar da ke cikin tafkin masu shugabanci a kan tafkin masu shugabanci mai sani, ya kira a cikin tafukar commutator bars ko kuma segments.

Single Layer Armature Winding

Ana yi tafki masu shugabanci a tafukar armature da ƙarin ƙiyasin. Idan akwai ƙiyasa, tafki masu shugabanci mai suna yana iya zama tafki masu shugabanci mai suna.

Duka, ana yi tafki masu shugabanci mai suna a tafki masu shugabanci mai suna. Ana cewa wannan ƙiyasa a single-layer winding.

Two Layer Armature Winding

A wasu ƙiyasar tafki masu shugabanci, tafki masu shugabanci mai suna yana iya zama tafki masu shugabanci mai suna; tafki masu shugabanci mai suna yana iya zama tafki masu shugabanci mai suna, tafki masu shugabanci mai suna yana iya zama tafki masu shugabanci mai suna. Ana yi tafki masu shugabanci a two layers winding haka saboda idan tafki masu shugabanci mai suna yana iya zama tafki masu shugabanci mai suna, tafki masu shugabanci mai suna yana iya zama tafki masu shugabanci mai suna a cikin tafki masu shugabanci mai suna a darajar da yake zama one coil pitch away.
