DC generator problems...HELP!

Hallo!


I have this small 12 Volt/DC motor I'd like to use as a generator. I've managed to generate 6 - 7 volts/dc max when I tested it, I wanted to plug that dc output from the 12 volt dc motor to another DC/motor or a rechargeable battery. What happens is the motor does not power anything I don't know why... Even when I'm trying to power DC appliances I can hear a strange sound coming from the DC/Generator(12 Volt motor) it's slowing down but not stopping it's as if something is holding it or the charge is not going through anything...
I don't know what to do I need to use that motor as a generator can someone please help me with this issue!


Here some additional information about the motor:

12 Volt/DC brush-less motor.
It generated under high RPM'S 12 to 13.5 volt's AC - 6 to 7.3 Volts/Dc


Heres a few images of how it looks like:

Thanks.

The references are to a 3 V DC motor (WB500 3V Constant Speed CD Player DC Motor )
This could be one of the reasons. Try motor with brushes. Usually such motors have a centrifugal speed limiting switch or a small electronic speed regulator. This could also come in the way.

The 3V motor is series wound with brushes. This means that the current from the battery goes through the field coils, making a stationary field then the current goes through the armature via the brushes, causing the armature to rotate. As the motor is rated at 1800 RPM, it will not generate much voltage until the armature is spinning at this speed and it also needs a load on it because, no load, no current, no magnetic field, no generated voltage.

Get a fixed field (magnets!) brushed motor, it will work better.
