Iyo yemagetsi conductivity yegraphite yakanaka kwazvo, inodarika simbi dzakawanda uye mazana enguva iyo isiri-simbi, saka inogadzirwa kuita zvikamu zvinofambisa senge electrodes uye kabhoni brushes;
Basa chairo recarbon brush
NdFeB magineti parizvino ndiwo ane simba risingaperi magineti.
Brushless motors anonyanya kushandisa isingawanzo pasi NdFeB magineti ane yakanyanya kuita,
