Basic Bedin circuit

[resonanceman]

I have  been getting ready to build A Bedini  motor

I  thought I had a few schematics of the circuits but  could not find them
It turns  out most of the circuits I have seen are on U tube.

Is this   a workable basic Bedini circuit?

I modified  a basic JT drawing  to make this  schematic

Are the  start  dots on the coil  the same in a Bedini as in a JT?

@resonanceman,

Something like this will run your motor.

Thanks  for the schamatic

It looks  very well done and  complete.


I see I was pretty close.
You  have  a pot and a resistor where I  just had a resistor.
You drawing  also has a neon....... I was going for as simple as possible  so I left that out.

I am  amazed at how  close it is  to a JT
I have no experience with Bedinis but I imagine  alot of my  experience  with JTs will help.

Edit

I missed the grain of wheat bulb
That is something  I have not seen before.
I am guessing it is acting  like  a resistor  .

It  hit me  a  little earlier that  the  parts on a board  are almost  the same for a Bedini as for  a JT

For the most part  the only differences are how things  are connected


That makes it  a little easier.
I have several JT boards  already made up.

@resonanceman,

The neon bulb is there to protect the transistor
against over voltage. If you disconnect the charge
battery then there is a high risk of blowing the
transistor.

The small bulb is like a RPM regulator on the motor.
The resistance in the bulb will vary with the
transistor base current. When the rpm increase
then the base current will be higher and the bulb
will "burn" more energy and the end result is that
the base current goes down again, thus keeping
the RPM stable.

Your JT experience will help. If you motor will not run
then just reverse one of the coils. Don't use Neos
on the rotor, use ferrite magnets. All north out. Also
get the coil as close to the magnets as possible.
A good rotor is the front wheel of a bicycle. Remove
the rubber tire and glue or use strong tape to hold
the magnets onto the wheel.

Good luck with your motor.
