what is the function of commutator in dc motor?
Answer Posted / waqas iftikhar
To keep the torque on a DC motor from reversing every time
the coil moves through the plane perpendicular to the
magnetic field, a split-ring device called a commutator is
used to reverse the current every 180 degree at that point.
