that was the best terminology i could come up with for using a "linear-motor" track to drive a "circular" wheel.

also i should note that with the above scetch, the magnets on the wheel should be slightly angled to produce directional motion.

pardon my unartistic abilities, the magnets should (in theory) be all evenly spaced and same size disk magnets.

all in repulsion to one another (same sides facing each other)

From what i can see with flux-paper and my fero-oil the "sticky points" are at (or near) the ends of the track where the opposite polarity comes up to meet them. at points before this, there should be "pure repulsion"

maybe im wrong here, perhaps the sticky-points will readjust themselves to catch a magnet entering and leaving the track from the middle.....

Hi,

Thanks for the drawing, now I understand.  Although a definite yes or no as to the operation could only be given by practical tests, I would tend to agree with your last sentence above.  (Selecting one rotary moment, an approaching magnet will encounter the same strength of repel force like a just leaving magnet, hence no force remains for any torque for rotation.)

Let me refer to an old thread from last year where a working setup from Helmut Goebkes was shortly mentioned:
http://www.overunity.com/index.php/topic,828.msg8155.html#msg8155

Though the working time of his setup was very short (he stated 40-50 second of self-run, starting by itself from zero speed!!!),  a reconstruction with ceramic magnets may well be worth the trouble.  With ceramic magnets eddy currents cannot be created in them and the amount of eddies in the soft iron parts will also be reduced, especially by using laminations.  By the way, the setup shown by Helmut can be found in some old patents too.

interesting is the intentional diversion of the magnetic fields, almost like Gray's motor.
