A possible implementation: basic considerations
I read through this file:
What I get out of it:
- A rotor with 16 magnets on its circumference (alternating polarity) is spun inside a coil L. The 16 magnets (as opposed to only one magnet) allow to reduce the revolutions per minute of the rotor to about 4000.
- the coil L, a capacitor C and a load resistor R are connected to form a L-R-C circuit (see drawing)
- the number of turns for coil L, the capacitance C and the value of the load resistor R can be calculated
My naive questions:
- How should the rotor be spun? E.g. with an electric drive motor?
- Approximately, how big should the rotor be for a 1 KW version?
- Once the target revolutions are reached the rotor becomes a self runner? What should be done with the drive motor at this stage? Can it be disengaged or does it have to supply some amount of torque continuously? How high would the input of the drive motor be in case of the 1 KW version (once it has reached target speed)?
- Can the load resistor L be a filament lamp?

P.S.: I just found these files:
depicting little coils, one coil for each magnet on the circumference of a rotor. The rotor has to be a ring, but there would be no easy way to hold the ring!
