Description: Two DC motors /dynamos were used in this experiment. With two pulleys, a flywheel and an electrolytic capacitor, the voltage and current of the primary motor passes to the secondary motor with energy transport.The peculiarity of the system is to find the right compromise between the various components. Material: 24V 20W wind generator. 3V toy motor. Electrolytic capacitor 25V 2200Mf max. Switch. Filament bulb 14V 5W. Iron flywheel 250 grams. Two specific rubber straps.
