in case of dc machines we use split ring where a complte
ring is splitted,in the number equal to the number of coils.
whereas slip ring is used in the case of ac machines in
where there is no need of converting ac to dc.
in short this split ring is used as mechanical converter in
case of dc machines.

we have consol make 3 phase servo stabilizer for cnc m/c. while installing the earth neutral voltage is 1.7 volts at stbilizer off condition and when stabilizer get on en voltage reaches 4.8 volts (new earthing is done and neutral is helthy condition all phase to neutral volts 440,442,441 v)why this happen.solution for cause.
