I do not possess a great amount of knowledge with regards to electrical engineering, but I have been reading lately about magnet-driven motors and how they have the problem of "sticking" so it got me thinking.
As per the crude diagram below (please forgive the photobucket link, but the picture apparently didn't pass security check) a rare-earth magnet is attached to a rotator arm which drives a low friction generator. Surrounding the system is a series of electromagnets which are sequentially fired on and off. As the EM immediately preceding the main magnet is turned on, the main magnet moves into the field. As it approaches the 'sticking point', that EM is switched off and the next one is turned on and so forth. Essentially, the main magnet is perpetually chasing a shifting magnetic field.
As the rare-earth main magnet is doing the bulk of the work, the EMs would not have to be very powerful at all.. just enough to persuade the main magnet. Therefore, I assume you could use relatively little power - even as much as a single 1.5 volt cell. Even a crude makeshift generator should be able to output more than that, n'est pas?
As I lack the knowledge and the resources to test this out, I figured I would post it here for smarter minds to tell me.. could this work?

Good advice Micro, I agree.
This idea of just pulsing an electromagnet when the rotor´s permanent magnet is facing the center point, has been developed by many inventors with many variations made by experimenters here and in other forums, look at the links on the right column in this page, or search: PULSED MOTORS (Adams motor, Muller motor generator,)
I am as you, with very limited knowledge of electronics, but I found in here a very impressive group of people prone to help and share their knowledge and their experiments, so don’t be disappointed by my words, on the contrary, go on and experiment; a huge field to learn and develop your creativity.
These kind of motors, can be made with just one or two “driver coilâ€, and yes, there are many variations which improve efficiency and low consumption;
The goal for all, is I think, to make a motor-generator able to self-sustain while producing excess of usable energy.
As I can see all over, this general idea is incrementing and enlightening in the population all around the globe, which is a reflection of the critical mass of consciousness growing very fast among humanity.

If it doesn't work, I can tell you probably why. :)
The magnets in these field array's communicate to
create one sticky spot of maximum power. The rotor
will need an additional helper pulse to get through this
sticky spot. If you could collect all the energy from
rotor going around the array and play it back as a
pulse at just the right spot with 100% efficiency then
the rotor would go around again. But in the real world
nothing is 100% efficient due to losses. So you are going
to need to add some extra energy from outside to offset
this inefficiency.
Your milage may vary.

What you describe here will end as a regular electro motor. These motors have not 100% efficiency, therfor energy must be supplied to make them run...
One cannot create a given potential without paying for it. This applies to literally everything we know of.

Hi Saosurvive
Your sketch looks a little like what I'm building based partially on the GAP principal of magnetic neutralization, on a 26" OD Alum rotor I have 12 very large rare earth magnets 2" OD * 2" L each & 13 coils on stator, on the back of the coils will be more magnets with S pointing in, The N rotor will be attracted to the S stator but when the critical lock up will happen the coil will be turned on Reverse, effectively turning off the S pole allowing the Rotor to pass, then the coil turns OFF letting the S stator pole repell the S rotor pole. there will only be 1 or 2 coils energised @ a time & approx 5 rotor magnets attracting & 5 repelling with out any electrical Pwr, each coil has a H bridge driver with diodes to send all BEMF & generated voltage back to battery, the Odd rotor to stator magnets greatly reduce magnetic cogging. 1 ft rotor radius is now ft lbs of torque.
application is EV drive motor with out trany.
