Introduction to DC Machine

4 Overview of Direct Current Machines Direct-current (DC) machines are divided into dc generators and dc motors. Most DC machines are similar to AC machines: i.e. they have AC voltages and current within them. DC machines have DC outputs just because they have a mechanism converting AC voltages to DC voltages at their terminals.
