Kushanda maitiro ecarbon brushes

Kushanda maitiro ecarbon brushes

Basa rekabhoni brush rinonyanya kuitisa magetsi uchikwesha simbi. Hazvina kufanana kana simbi iri kukwesha uye kuendesa magetsi kusimbi; Carbon brushes haaiti nokuti carbon nesimbi zvinhu zviviri zvakasiyana. Mazhinji ekushandiswa kwayo anoshandiswa mumamotor, uye maumbirwo akasiyana, mativi uye denderedzwa, zvichingodaro.

Carbon brushesakakodzera marudzi ese emamota, majenareta, uye ekisi muchina. Iyo ine yakanaka yekudzosera kuita uye hupenyu hurefu hwebasa. Iyo kabhoni brashi inoshandiswa pane commutator kana inotsvedza mhete yemota. Semuviri unotsvedza wekubata unotungamira uye unopinza kunze kwenyika, une yakanaka magetsi conductivity, thermal conductivity uye lubricating performance, uye ine imwe mechanical simba uye instinct ye commutation sparks. Anenge ese mota anoshandisa kabhoni mabhurashi, ayo ari chikamu chakakosha chemota. Inoshandiswa zvakanyanya muakasiyana AC uye DC majenareta, synchronous motors, bhatiri DC mota, crane mota yekuunganidzira mhete, mhando dzakasiyana dzemuchina wewelding uye zvichingodaro. Nekuvandudzwa kwesainzi uye tekinoroji, mhando dzemotor uye mamiriro ekushanda ekushandisa ari kuramba achiwedzera kusiyana

Basa chairo recarbon brushes

1. Wedzera kunze kwekunze (excitation current) kune rotor inotenderera (input current) kuburikidza ne carbon brush;

2. Kusuma static charge pane huru shaft kusvika pasi (grounded carbon brush) kuburikidza nekabhoni brush (output current);

3. Tungamira shaft yakakura (pasi) kune chidziviriro chekudzivirira kwe rotor pasi uye kuyera zvakanaka uye zvakashata pasi voltage ye rotor;

4. Shandura kutungamira kweyazvino (mune commutator mota, bhurashi rinotambawo basa rekuchinja)

Kunze kweiyo induction AC asynchronous motors. Kune mamwe ma motors, chero bedzi iyo rotor ine commutation ring.

Nheyo yekugadzira magetsi ndeyekuti mushure mekunge magineti yacheka waya, ikozvino inogadzirwa muwaya. Jenareta inocheka waya nekutenderedza magineti. Iyo inotenderera yemagineti ndiyo rotor, uye waya dzakachekwa ndiyo stator.
