DC machine are both motor/ generator works on
electromagnetic induction principle
MOTOR:
The current carrying conductor placed in magnetic field the
force exist on that conductor.according to Faraday laws of
electromagnetic induction principle.field indicates Flemming
left hand rule

GENERATOR:
When ever a conductor cuts the magnetic field the an EMF
Induced that conductor.according to Faraday laws of
electromagnetic induction principle.field indicates Flemming
Right hand rule
