Replication of the Jan P. Cack device?

The closest I got OU is the link here:

Thx Vidar

That on is on the CNC machine as I type
Gone for a 120mm Rotor with Rotor magnets 20mm in length which allows 16 of them to fit nicely with a 6 degree tilt.
Wanted to use the magnets I already have here, but looks like I will need to order some stator magnets. Will start a new thread when the Rotor cutout and mounted

@Omnibus, sorry mate I do not have a gauss meter, but as acp correctly say the friction and losses in the bearings and the Polycarbonate cogs is huge anyway. But even with the Rod magnets I used, there is not enough pull or push to even move a few mm. It just kind of balances itself out.

I will come back and play with it more another day, but for now I want to go for some really loose bearings on my next design and stick to single rotors.

Thanks for the feedback guys

Cheers

Sean.

What about needle bearings?

Here it is.

Thanks

The KissMotor:

The average torque on the satelites are 0.017Nm.
The average torque on the rotor is 0.68Nm

If we consider the tolerances, the result is practically zero.

There's this idea on Steorn that was inspired by the Cack device but is considerably different in many ways. I wonder what a FEMM or Maxwell model would reveal about it?

Hi all -

ClanZer - You are the MAN!  I've greatly enjoyed all of your replications of various devices.  Your enginering and construction skills are superior!

This idea is dead?  Looks like a more practical idea along the same lines as the WhipMag.

What about adjusting air gap?  Magnet size/strength?  Magnet spacing?  Rotor weight?

Changing gearing to bearing based rather than tooth based?  Stator magnets placed atop bearing (like a skate bearing) placed in a wheel (like a skateboard wheel) contacting the sun gear.  Providing a smooth motion - no impact with tooth losses.  Much less friction, yes?

Maybe manual starting speed of "x" m/s needed to get it going?

Additional "kick" magnet placed somewhere to give it the 1 spot of overbalance?

It's just with ALL these type of devices there are SO many variables one could mess with.

Should some of these be examined?  Or are you/we SURE this type of configuration would NOT work NO MATTER what?

Sure is a coooool idea.  I would be inspired to mess around with it if the design is possible.

(Thanks for sharing all your awesome replications ClanZer)
