2N2222A Upgrade

[duffer]

I am using a 2n2222a in a circuit described on YouTube. Please Google [i]lidmotor MAGGIE and the Snake Egg[/i] to see it. [url]http://www.youtube.com/watch?v=4TZj5y7bk94[/url]

Its a bedini type motor circuit.

I'm using 9 volt on the input.

I am trying to squeeze a little more power out of it but the 2n2222a is beginning to run a little warm. I will try using a heat sink and see how well that works.

Does anyone know how to select a transistor that can handle two or three times the power to use in this circuit?

Thanks

I don't know what a 'bedini motor' circuit is. I only know of someone called 'Bedini' who deludes people into thinking that they can get energy for free.

The base current of the 2N2222A is only limited by the (unknown) resistance of the 'B' winding. There are no coil details. The circuit is rubbish!

Correct, free energy and perpetual motion are complete nonsense.

On the other hand, here's a link to the circuit I am using [url]http://dickbrom.com/circuits/snakeeggspinner.jpg[/url] .

The diagram doesn't show the details of how the coils are wound, so here they are.
Coil A approximately 400 turns of 30 gauge wire
Coil B approximately 400 turns of 30 gauge wire
The coils are bifilar wound on a plastic spool 3/4 inch inner diameter, about 3/4 inch long. The coils are air core.
The magnet is a neodymium disk mounted on a brass shaft.

In operation the magnet spins up to about 5,000 rpm on 9 volts input but I want to go a lot higher.
Unfortunately the 2N2222A begins to heat up after about five minutes.

That's why I am looking for a substitute.
Any help would be appreciated
