The video he posted does not show convincing maintenance of speed for a brief period, due to the poor audio quality of his camera. He should use and display a tachometer.

I am in the process of machining a new Rotor to what my measuring with AC indicates. I do know that if the rotor magnets are not at the correct radius there will be No Joy. If the New Mag's work out as i hope then I will post them to the Group. I do not want anyone to work this until I see it for myself. No point in the others spending there funding on some thing that may not function. I have found this out that latching will and can occur even though the magnet radius is incorrect.

Will update what happens after testing.

To All Replicators and Groups,

Today after reconfiguration of the Stator magnets to a dual bearings I had a approximately 'one minute' self operation of the device and maintained a constant RPM once stator sync occurred. Note: What I mean by " Self Operation' is NO outside added input to the device.

I added the second bearing to the stator due to instability to each arrangement. The instability induced friction and consequently drug down the rotor speed. Also with the device, I am able at any time during spin up to latch any of the three Stators at any given time. In addition this allows me to have any combination of the stators running in synchronization.

My next step is to spend the necessary funds to Source totally all Non magnetic parts i.e. Bearings, Fasteners, Rotor center support shaft, etc. to construct a higher quality device.

I also understand that this is a variant of the original concept, but basic Engineering dictates that this is the next step.

Happy testing and may Your Rotors Rev up.

Look familiar? - (vipond50 posts photo of the rotor and stator spinning. He says it is from spinning by hand, no acceleration is achieved). (Jan. 18, 2008)

Specs

1. The Stator bearing is a R3-HA! manufactured by Bearings. This right off the box

2. The two bearings have a small thin washer" will mic " between them and another washer to give clearance off the base plate Will also get a Pic of the assembly layed out.

3. The Rotor mags are 1/4" diameter and 1/4" long N42's. I stacked them up (four) to give the length u see.

I machined a longer adapter to house the bearing

Stator Assembly

Here's a few Pic's of the Stator disassambled.

The Adapter is made out CPVC 1/2" tubing, what I had on hand, but seems to work very well. I counter bored the ID of the tubing so to accept the two(2) bearings (0.320") and also counter bored the opposite end to accept the 1/2 diameter magnet. The Length of the adapter is 1.00"

Data

Was looking at the Rotor to Stator ratios and logged these numbers.

Hand spin up with one Stator in Sync and the other Two stopped.

Rotor RPM - 667

Stator RPM - 2230

R = 3.348 to 1

Second Attempt

Rotor RPM - 736.3

Stator RPM - 2542

R = 3.4523 to 1

I did a count by hand a found that the stators rotate four(4) rev's/ one(1) rotation of the rotor.
