Can a DC motor connected with an AC generator act like an inverter?
If it can, then why isn't it used as an ordinary inverter?

yes, it can be used
Brush cummutator acts as a mechanical rectifier in a dc generator and as a mechanical inverter in a dc motor.
Field current is always in the same direction of a dc motor and the conductors under a pole moving in a specific direction will always have the same direction of current. Thus a brush will always be at positive potential and the other in negative potential (more correctly a brush will always be at higher potential than the other). Armeture current of a dc motor is always an alternating current. Thus the brush cummutator converts the supply dc current into ac current in case of a dc motor,ie., acts as an inverter.
it is not used because it is not soo efficient...... to its work.....
