I have a habit of relating magnetic field lines to acoustic standing waves and since inverse acoustic waves (and inverse electronic audio signals) cancel each other out, I thought the same should be true of inverse magnetic fields. I was expecting that the Group B iron inductor cores which are...

I will pick up 2 sample N55s and put them under my green magnetic field viewer film I based the design changes on your N42 zero to peak gauss curve - 110 mm centre to centre. I just assumed it would be more efficient to allow a full zero to peak sinusoid by spacing 40 mm from the edge. But...

I've updated the design to account for adjacent magnetic field geometry at 110 mm centre to centre spacing. To keep the flywheel size within 1 m Ø I've reduced the magnet count to 20 so at 20 rev/s the frequency is now down to the aviation standard of 400 Hz This not only improves the...

Dels and curls are what make Maxwell's equations the next best thing to a nervous breakdown. Yepp, small steps in the right direction are way better than giant leaps towards catastrophe I'm glad I decided to post these problems here, your input has been extremely helpful. Hopefully after some...

Aha, so for N42 the centre to centre spacing between magnets would need to be 110 mm for a zero to peak sinusoid, and for N55 an even wider spacing. of course, a square wave would be ideal, since a square wave would rectify to flat DC without the need for a second wave 90° out of phase. I...

Jim, do you think a 10 mm spacing between magnets will produce an unbroken sine wave? I will not be able to test the output with an oscilloscope until both the flywheel and 1 transducer coil are completed, and once I build the flywheel I've already invested quite a bit of time and money in...

This is a simplified example of the design - showing only 1 transducer coil in the actual working model - there are 120 transducer coils operating independently 60 on either side of the flywheel, Group A and Group B - 90° out of phase with Group A. The target output for each transducer coil is...

nice demo* In the north of Sweden you can see the Earth's magnetic field in living colour (green) otherwise known as the 'northern lights'. Aha, okay.. I've always interpreted the term 'armature' as the rotating electromagnet and drive axis of a motor. Hm.. what model car do you have...

There is no armature and no stator in the design. Here is an image of an armature : http://www.gearseds.com/curriculum/images/figures/web_met_armature_and_brushes.jpg the magnetic field induced in the armature coils creates an electromagnet which repells the permanent magenets in the stator...

That's actually more than true, given that most of the population are quite familiar with basic electric units : Volt, Ampere, Watt, Ohm.. even those with no interest in electronics, but relatively few people have ever heard of SI magnetic units : Weber, Tesla, henry.. even within the magnet...

Hello, I'm afraid you have indeed misunderstood the design, as there is no armature and no stator. A standard generator is simply a motor operating in reverse, so rather than 'drawing' current to drive an armature.. standard generators 'produce' current when their armature is externally...

If you mean the air gap between the poles of the flywheel driver magnets and the tops of the inductor cores, the mechanical clearance gap would be no more than 1 mm. you can get a good mental picture of the design if you visualise an 810 mm Ø x 30 mm disk flywheel rotating on an x axis, with...

Thanks Jim The transformer tutorial has quite a lot of useful equations and information that apply to any type of inductor. Some of which has actually helped solve some core eddy current and loss issues there is also a current capacity issue the current capacity of copper wire is 3 A / mm² ...

I wonder if using a bifilar coil would be a solution it depends on whether or not the strands of a bifilar winding are counted separately per turn

so now I've made some extreme design changes to the inductor new values : 10 mm x 10 mm soft iron laminated square core (chamfered or slightly radiused edges) 36 turns of 1.5 mm Ø polysol insulated copper magnet wire, wound directly to core resistance : 0.01 Ω / m x 2.88 m = 0.0288 Ω DCR...
