Any one tried to use Adams idea to get over sticky spot?

Hi All,

After the excitment of the mervace thread, i got to thinking. Has any one tried to use Adams idea to get over the sticky spot in the takahashi type of motor. Wouldn't it be nice if we could remove the externally powered electromagnet with one that produced enough kick with the passing of the rotor.

Or it doesn't work we can tune it to the bbc and post it on you tube working.

LOL

Hello Craigy,

that's my idea since I had seen Merv's engine, too.

Let's development it.

I am up for this and have been playing with a pickup coil I ordered from
http://www.freelights.co.uk/how.html

This Coil creates alot of energy from little input. I have waved a really weak ferrite magnet over the top of this pickup and it creates enough AC voltage to light 3 LEDS on one stroke and 2 on the reverse with not a lot of effort, these LED's light up very bright.
Placing this units against one of my wheels with just 2 magnets attached gives a nice steady AC pulse.

I am not sure that a pickup coil, a reed switch and a second coil will be enough, so have ordered some germanium diodes to build a Bridge rectifier with small voltage drop and also a 16V 10,000UF Cap to store the pulses of energy created by this coil. This will hopefully store an enough DC power.

I reckon if I I can use 4 magnets on a wheel, then 3 of the magnets pulsing the pickup coil may be enough to store enough energy in the Capacitor to trigger the Electromagnetic coil onto the 4th magnet during rotation.

Of course the Reed switch will come into play based on maybe a seperate magnet spaced away from the main group to get the timing correct.

Will post some pictures when the bits arrive.

Sean.

Hi Peter,

i am not sure that the rotor passing over coil will provide enough power on its own in the wankel type of motor.
But,..And its a big but. What if we try and harness the power of the rotor on its way around to top dead centre?
i.e. place coils and stator magnets around the rotor, as the magnets push the rotor around and towards top dead centre where the trigger magnet is, the rotor induces a current in all coils it passes which is used to charge an electrolytic capacitor.
Now when the stator reaches the traditional sticky spot we use the standard adams back emf idea plus use the charge in the cap to get over the sticky spot.

Now i have heard it said, that to get over the sticky spot one requires more energy than the system can produce. i.e 101 percent since all energy gained is dissipated in the sticky spot. But is that assumption correct?

Here is a magnetic wankel concept video for those of us who need to see what we are talking about.

What do you think?

Clanzer , i was writing the previous post at the same time as yourself. Great minds think alike i believe..
