    Yes. It is just not possible to generate more electricity than that motor consumes.

    Sure: Couple an electric (DC) motor to another, and the driven motor becomes a generator. If you hoping for a perpetual motion machine, fugeddaboudit.

    It is possible.In synchronous motor you can generate reactive power by overexcitation.Induction motors can also be operated in the generating zone through variable speed drives
