I like how the control circuit and the quartz crystal are built together with the stator. These are the simpliest 1 phase 2 pole stepper motors. If you take a close look at the stator poles... you will see the simpliest way ever how its creating torque from such little power at 1 phase only. The stator poles are offsetted to each a very bit so the rotor magnet can get smaller air gap at one half of the poles than at the other halves of each.

thanx for your comments

This might work awesome for a discharge of bedini caps to second battery.

good idea!

insted of puting the electro magnet directly under then hanging magnet. put it next to it. from: | | o ^ to: I I o < | = string o= magnet ^/< = electro magnet

having trouble with the magnet wanting to stick to the electro magnet,with side on pulsing-i need to make a proper pendulum,thanx for commenting

I was wondering where the quartz was lol. Now I see. Its the piezoelectrical current.

How do you amplify that movement...

The simplest way is to make a pendulum that resonates at the frequency of the circuit. Then, there's the possibility to make a driver circuit by adding a coil with a ferrite core, which will pick up the small signals; feed these impulses to a cheap standard operational amplifier based circuit (which has a high input impedance), and presto - you will have amplified impulses at the output, that you can use to drive a larger pendulum (or some other load).

So at the dead point, the rotor magnet pole points not in straight line with the stator poles, but in an angle to them, so when the stator flips polarity, the repulsive forces become asymmetrical and there will be torque to flip over the rotor.

This is a pulse motor as well, since power only needed to initiate the rotor flipover. The rest of the work is done by the magnet itself. So, these clocks use this very efficient way of power saving since long ago now.
