2019-2-10 There is no basic difference in the construction of a DC generator and a DC motor.. In fact, the same DC machine can be used interchangeably as a generator or as a motor. Like generators, there are different types of DC motors which are also classified into shunt-wound, series-wound and compound-wound dc motors.. DC motors are seldom used in ordinary applications because all
