5K40.80 Genecon Hand Crank Generator
Electromagnetic induction, conservation of energy, Faraday's law, motors and generators, DC signal generation
The Genecon motor/generator is a motor or hand cranked DC generator that is used to drive another Genecon motor/generator and/or to light a series of LEDs.
-  Genecon motor/generator (a handheld device that can be used as a motor or a generator)
-  Breadboard with LEDs
-  6 V light bulb
-  Bi-coloured LED
-  1 F capacitor
- The Genecon motor/generators are fragile. Handle with care.
- The capacitor has a polarity. Do not apply a negative voltage to the positive side of the capacitor.
- The apparatus is small, but the handle motion and lights are visible in large lecture halls.
To drive another motor/generator:
- Connect the leads of two Genecon motors/generators.
- Crank the 'generator' handle. The 'motor' handle will rotate.
- Hold on to the 'motor' handle. Notice that the 'generator' now requires more effort to crank.
To light a series of LEDs:
- Connect a Genecon motor/generator to the circuit.
- Turn the crank of the generator at a speed that lights up the LEDs.
- Turn the crank faster, notice that the brightness increases.
- Reverse the crank, showing directionality of the LED operation.
To light a light bulb:
- Connect a Genecon motor/generator to the 6 V bulb.
- Crank the generator handle. The bulb will light up. Note the dependence of brightness on cranking speed and direction.
To light the bi-coloured LED:
- Connect a Genecon motor/generator to the bi-coloured LED.
- Crank the generator handle in one direction. Note which colour lights up.
- Crank the handle in the other direction. Note that the other colour now lights up.
To charge and discharge a capacitor:
- Connect a Genecon motor/generator to the 1 F capacitor taking care to account for polarity.
- Crank the generator handle again taking care to account for polarity.
- Ask students to vote on which way the handle will turn when released.
- Release the handle. Note the direction it turns.
