Momwe mungachepetsere phokoso lamagetsi (EMC)
Pamene mota ya DC brush izungulira, mphamvu ya spark imachitika chifukwa cha kusintha kwa commutator. Spark iyi ikhoza kukhala phokoso lamagetsi ndikukhudza dera lowongolera. Phokoso lotere likhoza kuchepetsedwa polumikiza capacitor ku mota ya DC.
Pofuna kuchepetsa phokoso lamagetsi, capacitor ndi choke zitha kuyikidwa pa malo omalizira a mota. Njira yochotsera bwino spark ndikuyiyika pa rotor yomwe ili pafupi ndi gwero, zomwe zimadula kwambiri.
1. Kuchotsa phokoso lamagetsi mkati mwa mota poyika Varistor (D/V), annular capacitor, rabara ring resistance (RRR) ndi chip capacitor zomwe zimachepetsa phokoso pansi pa ma frequency apamwamba.
2. Kuchotsa phokoso lamagetsi kunja kwa mota mwa kuyika zinthu monga capacitor (mtundu wa electrolytic, mtundu wa ceramic) ndi choke zomwe zimachepetsa phokoso pakakhala pafupipafupi.
Njira 1 ndi 2 zingagwiritsidwe ntchito padera. Kuphatikiza njira ziwirizi kudzakhala njira yabwino kwambiri yochepetsera phokoso.
