Unganciphisa kanjani umsindo we-electromagnetic (EMC)
Lapho i-DC Brush motor ijikeleza, i-spark yamanje yenzeka ngenxa yokushintshwa komdlalo. Le spark ingahle ibe nomsindo kagesi futhi isebenze umjikelezo wokulawula. Umsindo onjalo ungancishiswa ngokuxhuma i-capacitor ku-DC imoto.
Ukuze unciphise umsindo kagesi, i-capacitor kanye ne-choke ingafakwa ezingxenyeni zemoto. Indlela yokuqeda ngempumelelo inhlansi ukuyifaka ku-rotor eseduze komthombo, okubiza kakhulu.
1.Engathandela umsindo kagesi ngaphakathi kwe-motor ngokufaka i-varistor (D / v), i-capacitor ye-ancur, ukumelana kwendandatho yerabha (RRR) ne-Chip Capacitor yehlisa umsindo ngaphansi kwemvamisa ephezulu.
2.Limiating Electrical Noise ngaphandle kwe-motor ngokufaka izingxenye ezifana neCapacitor (Uhlobo lwe-electrolytic, uhlobo lwe-ceramic) nokudonswa okunciphisa umsindo ngaphansi imvamisa ephansi.
Indlela 1 no-2 ingasetshenziswa ngokwahlukile. Ukuhlanganiswa kwalezi zindlela ezimbili kuzoba yisixazululo esihle kakhulu sokunciphisa umsindo.
