Can i get infinite energy! ?

    Please help me
    If I put a dynamo in a space ( no air ) ... and I gave it a movement ... to produce energy. ... and considered to delete any friction between its parts ... will it move forever producing infinite energy !!?

    No, it will work only till the kinetic energy of the rotor is converted into electricity.

    There is no such thing as a free lunch.

    The dynamo will keep spinning until you connect it to a load. Then it will slow down and stop.
