Self-Runner NS Coil Pulse Motor Live Video Stream. It's been going for months!

[Rosemary Ainslie]

Laser's rig is a simple motor. As a magnet activates the first reed switch, current flows through the windings of the coil. This creates a magnetic field which attracts the magnet towards the pole. As the magnet passes by the pole, the first reed switch opens up and the field collapses. No more attracting force.
Somewhere around this time the second reed switch closes. This sends current in the opposite direction through the coil, which then creates an opposite polarity magnetic field at the pole, which in turn pushes the magnet away from the pole.

Ted.  Thanks for answering this.  That's exactly as I saw it.  In other words there's a push/pull on each magnet as it passes the switches.  Therefore the switching speed determines the rate of rotation.  What I was not sure about is whether the 'motive' force was from the initial magnetic 'attraction/repulsion' or whether the voltage/amerage on the coil was independent.  Perhaps both?  But I do suspect that the inductive condition of the coil is such that it could initiate this movement.  In which case what?  Does that mean that the magnets on the rotor do not actually 'change' the inductive condition of the coil.  It's purely reactive?  Not sure if the question is clear. 

Laser's rotor is also turning much faster than it appears in the video. The frame rate of his camera synchronizing with the speed of the rotor makes it appear to move slowly.
I hope this helps clarify things a bit.

I never realised this.  Thanks for explaining things here Ted.  I suspect I've been taxing your patience.  I also realise that if the 'replicator' video that I saw also had a smaller diameter then it would appear to be moving quicker.  Do you have a rough measure of that rotor?  If not, don't worry because I can make a guess from comparing it to the size of the coil.  I think laser actually mentions its length.

Thanks again
Kindest as ever,

Ted:

I believe you are exactly correct. 

I was also thinking that the same thing might be accomplished using a small transistor, say a 2n3904, and a single coil near the rotor ala Bedini.  Sort of a solid state Stubblefield coil.  Of course, you would have to have the output to fire the transistor at or above its threshold but this should not be a problem.  I was getting 1.32 volts at 5 mA's on my second Stubblefield coil attempt.  More than enough to do the job I believe.

Bill

Wow.  Have I got this right?  You'd use the rotor to induce the current to drive the transistor?  That's so neat.  I also wondered about the implications of using the rotor to generate current flow.  Very neat indeed. 

Well done Pirate. 
Kindest regards,
Rosemary

Rose:

No.  You use the output from the NS coil to drive the transistor which fires the coil which then drives the rotor.  It would be the same as the one magnet-no bearing Bedini motor design of Jonnydavro.  I have a Youtube video of my earth battery powering one of these.  Just a single coil and a transistor.  No reed switches.

I hope this is more clear now.  Lidmotor just released a video of his Stubblefield coil running one of these.  He also added a pick-up coil to the rotor and can light leds from that as well.  I believe he still used the reed switches and no transistor though. Worth checking out.

Thanks Bill.  I think I get it.  Would LOVE to see that video if you've got the time to add the link.  Effectively the reed switch is simply replaced by a transistor?  Hopefully that's right.  I still rather suspect that a second simple coil in proximity to the rotor should generate a current.  But presumably that would come when we explore the work this rotor can do. 

Ta muchly Bill.  I'll try not to plague you all with my muddles.   

Kindest as ever,
Rosemary.

Here is one of Lidmotor's videos running a one magnet no bearing Bedini motor from an NS coil:

Here is a great video he did on the Stubblefield coil:

Here is my video of my EB running a Bedini motor:
