Answer:
Any DC motor with permanent magnets can easily be a generator. It doesn't matter whether it is brushed or not; brushless motors make great generators but you will need to add a rectifier to get a DC output.
If the motor has a separate field winding instead of a permanent magnet, you will need to energise that winding from an external DC source, e.g. a battery.
To use the device as a generator, the coil can be spun, inducing a current in the coil. An AC (alternating current) generator utilizes Faraday's law of induction, spinning a coil at a constant rate in a magnetic field to induce an oscillating emf.
