how to charge a capacitor with small voltages

Hi,
I’ve got a flywheel driving the rotor of a dc brushless dc motor, and I want to store the generated electrical energy to a reservoir capacitor.
The question is that how can I take out all the energy out from the rotary energy of the flywheel. As we know, while charging up the capacitor, the rotational speed of the flywheel reduces, hence the induced voltage at the generator output reduces, and the current cannot flow into the capacitor.
Are there any solutions can conquer this problem?
Thanks.

    But why do you want to store the energy in a capacitor bank???

    anyway the problem seems to be too much of capacitance in the circuit. Add inductance in the circuit to cancel out the excessive capacitance.

    Please clear me the function of a dc motor there and why are you storing the electrical energy in capacitor bank??

    and yes please mention what type of capacitor bank are you using??
