help with my Newman machine

[Peacemaker]

Hello Peace lovers,

Please look at the jpg. and tell me if the design can be an effective motor.

I am having dificulty verifying that my coil is a magnetic field.

Please look at the orientation of the axis of the magnet relative to the circumferance of the coil. Note that the axis is parallel to the rotation of the coil.  Does the axis have to be perpendicular to the coil?

Also, is the kind of wire I am using alright? I am using 50 ft. of 14 gauge pvc inslated copper wire.  What is the best wire, insulation and lenght?

What is the best initial power source?  Do I need fancy equipment like big car batteries and capacitors?

See attached jpeg.

Thanks,

It will only produce a magnetic field proportional to the amount of current you run through it.

Yes. It won't turn the way you have it drawn.

Try at least 1000 feet of 20 ga magnet wire. The more wire the better.
It will run on 10 feet of wire if you put enough power to the coil. However, the point with this motor is to get more back than you put in. To do that you need lots of wire.

What is the best initial power source?  Do I need fancy equipment like big car batteries and capacitors?

You'll need the car battery if you only use 50 feet of 14ga wire. I wrapped my motor with about 3000' feet of 20 ga and ran it for 10 hours on a little 9 volt alkaline battery. I expect to do much better than that once I tune it up.
The fun part is building the commutator.

What's with the ABS?

Thanks a lot Eddy you were very helpful. 

What is a commutator and how do I build it?  What is the significance of this part of the machine.

I redesigned my machine and got a little more action.  I verified that I created a magnetic field.  The magnet inside went from loose to straight up and down.  But it would not rotate.  In fact, it resists movement when the current is running through the coil.

I will post another diagram shortly. 

Where can I get the wire you suggested for cheap.  How about good magnets like permanent earth magnets?  And what about a good spinning axle with bearings and stuff.

I chose ABS because it is cheap and easy to manipulate (cut, drill, glue & mold).

What do you reccommend.  Where can I find a good schematic of a Newman Machine and step by step instructions and a list of good material.

Thanks again,

I admire your spirit but you don't know anything about motors do you. 
Well, this is about as simple a motor as you will ever make.
This motor works on the principal of pulsed DC current. Once every revolution, at the same place in that revolution, the coil is "pulsed" with current for some short period of time (less than a quarter turn). This creates a magnetic field through the middle of the coil which interacts with the field of the permanent magnet. The permanent magnet will then rotate to align itself with the coil field. That is where the work is extracted.
The timing of this pulse is very important. If the coil is pulsed when the magnet is aligned with the field, no rotation will occur. Therefore, we want to time the pulse so the magnet is at around 90 degrees offset to the plane of the coil.
When we pulse the coil at that angle, the magnet will turn one way or another according to the polarity of the pulse. Before the magnet gets aligned with the coil we cut off the current. This allows the magnet to continue rotating past the alignment point and around to 90 degrees again where we then pulse it once more.
The commutator is a device that allows you to pulse the coil at the same particular point in the rotation. This device can be as simple as a bare spot on the shaft with a piece of wire rubbing to make a contact.
Look at some of the machines in this forum for ideas. Also study the pictures to get a better idea of the geometry of these motors.

Hi PeaceMAker,
you have the coil and rotor not setup right.
One piece of them must be positioned turned by 90 degrees to get it to work.
