I have searched very much on the internet,Some links tell me very good points,When i oscoping the motor leads,i found that two ferrite beads plus a 0.1uf and 100uf parallel caps near motor leads totally eliminate noise in other side of ferrite beads,but the noise in adc section of mcu exist yet,
it seems it is for coupling between shaft encoder and motor,and shaft encoder must be opto coupled, |
