Carbon brush dambudziko mhinduro dzekabhoni brashi mota

Brushed DC mota uye Brushed AC mota inofambiswa nekabhoni bhurashi uye commutator pole kusangana kuti irambe ichitenderera, saka brashi uye commutator pole friction haidzivisiki, zvakare nekuda kwekuenderera kunotsvedza kukweshera, kumwe kufenda kutsva kwakajairika.Asi dzimwe nguva, kunyanya mushure metsva. brashi inotsiviwa, iyo spark ichave yakakura, kupfeka kwebhurashi kuchave nekukurumidza, mumatambudziko akakomba, kuchapisa rotor.
Zvikonzero zvekunyanya kupenya kwekabhoni brashi uye mhinduro:
(1) Iyo kabhoni bhurashi haisi iyo fekitori yekutanga, uye kabhoni brashi yakanyanya kuoma kana mhando haina kuzadzisa zvinodiwa.Mhinduro: tsiva iyo yekutanga fekitori kabhoni brashi
(2) Kusaenzana kwechirimo kudzvanywa pane kabhoni brashi ye Brushed DC mota uye Brushed AC mota.Solution: gadzirisa kudzvanywa kwechirimo zvakakodzera kuchengetedza kudzvanywa kwega yega kabhoni brashi yakaenzana
(3) Chibatiso chebhurashi chinova chakasununguka.Solution: simbisa bhurashi grip mabhaudhi kuitira kuti brashi inobata uye iyo commutator surface ienderane.
(4) Chinhambwe chiri pakati pebrashi grip necommutator surface chakakurisa.Solution: Gadzirisa chinhambwe pakati pebrashi grip uye commutator, kazhinji 1 ~ 3mm
(5) Kusangana kwakashata pakati pekabhoni brashi uye commutator.Solution: Iyo kabhoni bhurashi inogona kupfekwa ipfupi, uye panosangana pamusoro pekabhoni brashi inogona kukuyiwa kana kutsiviwa nekabhoni bhurashi nyowani.
(6) Kusawirirana kusiri pakati pekabhoni brashi uye brashi grip.Solution: haina kunyanya kusimba kana kusununguka zvakanyanya, kuve nechokwadi chekuti bhurasho riri munzvimbo inopisa rinogona kutsvedza zvakasununguka mubrashi rinobata, rakanyanya kusimba rinogona kushandisa sandpaper kuenderana nekabhoni brashi jecha, rakasununguka kutsiva kabhoni brashi nyowani.
(7) Kana iyo mica pakati pemahwendefa emagetsi isina kuchena, shandisa broach kuti ubvise mica yakasara.Solution: mica inobudikira pakati pemaplateti ekomutator uye zvakanaka shandura commutator
(8) Pakati pemubati webhurashi haisi panzvimbo yakakodzera.Mhinduro: fambisa chibatiso chebhurashi uye sarudza yakanakisa nzvimbo ye spark
(9) Short circuit ye ​​commutator coil.Solution: rewind coil
(10) Armature winding short circuit.Solution: disassemble iyo Brushed DC mota kana Brushed AC mota, tarisa iyo armature winding, shandisa millivolt mita kuti uwane yakavhurika yedunhu, kana isingakwanise kusungirirwa, ichave yakadzoserwa.Kana mamiriro asipo, tsiva iyo armature itsva.
