Ungawunciphisa kanjani umsindo we-electromagnetic (EMC)
Lapho i-DC brush motor izungeza, i-spark current ivela ngenxa yokushintsha kwesihambisi. Le nhlansi ingase ibe nomsindo kagesi futhi ithinte isifunda sokulawula. Umsindo onjalo ungancishiswa ngokuxhuma i-capacitor ku-DC motor.
Ukuze kuncishiswe umsindo kagesi, i-capacitor kanye nokuklinywa kungafakwa ezindaweni zokugcina zenjini. Indlela yokuqeda ngempumelelo inhlansi ukuyifaka ku-rotor eseduze nomthombo, okubiza kakhulu.
I-1.Ukuqeda umsindo kagesi ngaphakathi kwemoto ngokufaka i-Varistor (D / V), i-annular capacitor, ukumelana nendandatho ye-rubber (RRR) kanye ne-chip capacitor enciphisa umsindo ngaphansi kokuvama okuphezulu.
2.Ukuqeda umsindo kagesi ngaphandle kwemoto ngokufaka izingxenye ezifana ne-capacitor (uhlobo lwe-electrolytic, uhlobo lwe-ceramic) kanye nokuminyanisa okunciphisa umsindo ngaphansi kwefrikhwensi ephansi.
Indlela 1 no-2 ingasetshenziswa ngokwehlukana. Ukuhlanganiswa kwalezi zindlela ezimbili kuzoba yisixazululo esingcono kakhulu sokunciphisa umsindo.
