Kundel Motor

[Liberty]

I would think that if the magnets were bigger around, say like 12 inches or larger, that the torque down at the axle would be increased by the larger magnet ring turning it providing more leverage. 

I agree that a small generator should be attached to see what he can get out of it.  I am at the same point on my motor.  Stepper motors are a good choice for low rpm motors (see web page below), and small permanent magnet dc motors like RC car motors or toy motors are a good choice for higher rpm motors.  Here is a web page that may be helpful to others needing to make a small cheap generator to test a motors output with a stepper motor.

I really like what he (Kundel) is doing.

He is not showing a bunch of vague drawings and sketches.
He is not making a bunch of wild claims.
He is not talking about threats on his life.
He is not hiding behind a veil of secrecy.
He is not leading people on wild goose chases.
He is not selling "snake oil"
He is not asking for money.

He is building an interesting motor that actually rotates, and putting it out there for everyone to see.

Clearly this is not an "overunity" or PMM, and he doesn't claim it to be.  It is innovative and functional, though, and I commend him on his approach of showing something actually working before making a bunch of wild claims.  The concept of creating rotation from reciprocation (and vice-versa) without contact between the rotator and reciprocator is noteworthy itself.

I like this guys style.

Jake noticed the same thing I did about Kundel making no claims to OU.  What he has done is given us another way to look at magnets and motors.  I think we'll get this thing down once we have the right perspective.  I'm pretty sure it will be a mechanical method of opening and closing the gate to go full circle. At least until we get slicker at manipulating fields.

I have assembled a basic Kundel motor to study the effect.  (Without the actuator coil.)  I assembled a sliding apparatus to hold the actuators and moved them back and forth with my hands.  It pays to "feel" what magnets are doing. 

What I have gathered from my plastic version is that the faster it goes, the less distance the actuator has to move.  I would imagine that once a motor like this gets up to a certain speed, you would only need something like a vibration or sound wave or some other kind of micro-pulse to keep the actuator moving "in rythm" so to speak.  Just using my hands, I have to start off moving it back and forth about an inch.  After about 12-15 rotations, I only have to use the slightest movement to keep accelerating until it goes too fast for me to keep rhythm.  Add a flywheel and there could be some decent torque in addition to high rpm's.  Although I can appreciate the Sprain design, it seems to limit its rpm's by it's inherent design.  The Kundel motor just wants to go faster! 

We need something that starts off vibrating "big" as far as amplitude and low in frequency and then ends up "small" in amplitude and fast in frequency.  I imagine a sound like the beginning of "THX" movies. 

I'm thinking of hooking a speaker up to the actuator and slowly bending a low frequency note up in pitch until the motor max's out.  Even if I have to kick start it to get it to the point where it will self accelerate off of about 20-30 hz.  I know from running sound that you need way less wattage to run midrange speakers and tweeters that you do for the low freq subwoofers.  Eventually, you could go supersonic in frequency and use a less and less energy in theory, right?  So with a flywheel and possible "Supersonic" capabilities, the puppy might be able to rock the house!   

Thoughts?

Yes, I think the way he has it built, with the reed switches, it gives itself it's own upper limit. We take what we know about resonance, and mechanical gating, and this thing could be fun. How to lower the reciprocating action once it gets up to speed though?

[konduct]

The reed switches may be helpful for startup, then disengaging once a "sonic" rpm has been reached.  I'd rather just spin it up manually, then hit that bass note to take over.

If I had a "super speaker" that could go sub-sonic, it may even self start.  Either that or I will have to lower the tolerances on this particular build.

**By the way folks...I didn't have to cut ring mags to get this to work.  I've been recycling the same old neos for most of the designs I've worked on.***
