DC Generator. Commutator is the point of contact between the winding and the brush of generator. It switches the field of rotor in opposite direction to convert sinusoidal AC to pulsating DC which is than rectified using filters to get proper DC output
by
Dc generator coz it is used to convert unidirectional dc into ac by changing direction of the current every half cycle
