Principle�of�operation
A�commutator�consists�of�a�set�of�contact�bars�fixed�to�the�rotating�shaft�of�a�machine,�and�connected�to�the�armature�windings.�As�the�shaft�rotates,�the�commutator�reverses�the�flow�of�current�in�a�winding.�For�a�single�armature�winding,�when�the�shaft�has�made�one-half�complete�turn,�the�winding�is�now�connected�so�that�current�flows�through�it�in�the�opposite�of�the�initial�direction.�In�a�motor,�the�armature�current�causes�the�fixed�magnetic�field�to�exert�a�rotational�force,�or�a�torque,�on�the�winding�to�make�it�turn.�In�a�generator,�the�mechanical�torque�applied�to�the�shaft�maintains�the�motion�of�the�armature�winding�through�the�stationary�magnetic�field,�inducing�a�current�in�the�winding.�In�both�the�motor�and�generator�case,�the�commutator�periodically�reverses�the�direction�of�current�flow�through�the�winding�so�that�current�flow�in�the�circuit�external�to�the�machine�continues�in�only�one�direction.
