Simple Motor‑to‑Generator Conversion: Turning a Toy Motor into a LED Power Source

Generator From Motor. Very Basic Model.

Here we used two 12 Volts toy/ Old Tap-recorder Motors(From trash). One as a Motor ( Turbine) and other one as a Generator/alternator. A white LED is connected as a Load to the Generator Output.

Note That this is seems to be a Motor-Generator Set, but No.. Because Motor-Generator Set ( AC Motor and DC Generator) used as a Convertor (AC to DC and vice versa), and here we used it for glowing an LED ( For showing that how can we use a DC motor as a DC Generator).

Here, we are going to step by step procedure.

Requirements:

2 Toy or Old Tap recorders Motor (one as a motor and other as a generator)
1 LED
One big rubber band as a belt
2 pulleys (one small and other is large one)
Flexi wire
4 screws
Wooden piece
Metal strip

Procedure:

Install both motors (one as a motor and other one as a generator) on wooden piece tightly by metal strip and tight the screws.
Connect both motors (one as a motor and other one as a generator) by rubber band or belt which is fixed in the pulley.
Connect an LED to the generator output (Red and black)
Connect the motor with 12VDC, and run it as a turbine. It will rotate the armature of generator by belt and current will produce in the generator that will glow the LED.
