Hmmmm...

The load test was really interesting!
I hope someone here will contact the inventor for more details.

hi,
I've spoken to the builder of the motor Ian, and he's kindly given a link to his site:-

http://www.mintakafulcrum.net/

This was listed on the youtube page but I must  have missed it when I looked.
Anyway it's got lots of info, including circuit diagrams and plans.

is there any differences from step motors?

Well main difference is that a Stepper motor is input only. So you have a number of coils inside a stepper motor and power is applied to all coils, this keeps the motor in a static position. Then you pulse each coil in the correct sequence to get acurrate movement. Common Steppers take 200 pulses for a full revolution, so excellent for CNC/Milling machines where accuracy is needed.

The pulse motors shown are moving the rotor away or towards the coils by a simple pulse to a electromagnet, but also there are coils that are pickups to collect the energy created by the magnets passing over them, again around the rotor.

So basically the idea with a pulse motor is to get more energy produced by the coils around the rotor than the energy used to drive the other coils that act as electromagnets.

After months of watching ebay to get some decent priced electromagnets, today I actually spotted some that look ideal for a pulse motor and won a bulk lot for a good price. I could of wound them myself but wanted manafactured graded ones that have equal power. I will probably have to wind the pickup coils myself, but in saying that there are a few Motor Bike Stators going cheap on ebay that may be ideal.


Regards

Sean.

but i think step motor can be used as a pulse motor.

some step motor have a permament magnet rotor.

here some step motor images.

If you say pulsed coil 1 and 3 to drive the stepper, are you going to get more power out of the coils 2 and 4 to created more power?

You could pulse a stepper and it would turn and pull alot of current as it is designed that way.
You could attach a wheel to a stepper and use it as an alternator, at low revs they work fine, but as soon as you speed them up you get alot of resonance back.

Hy,

I'm french, and i have some problems to understand all on this website:
http://www.mintakafulcrum.net


1 - In this uTube page http://www.youtube.com/watch?v=f4gAKrn5pl4, the video publisher said:
Quote
The motor uses about seven watts of electricity, yet the mechanical output is 4 to five times that of the electical input. I hope that helps.

2 - Does someone find this information on the website http://www.mintakafulcrum.net, and wich motor model who do that ?

This motor seems efficient, can someone work on it ?

Hi everyone.

I am the builder of the motor that was posted here. Stephan asked me to come by and discuss it.

I just posted a new video here:

http://www.youtube.com/watch?v=5oIZTZeC6c4

This is just a demonstration to compare with the other motor first posed here. The rotor is the same. The coil in this one is about 1.2 ohms and is bi-filler wound with the second coil picking up the bemf.

This uses the same amount of power running with one coils as the other motor with eight coils. Yet this one I can stop with two fingers, and the other I could not stop with all of my strength in my hand without burning my fingers

The single coil motor here runs at 2325 rpm and the one with eight coils at 2400 rpm. So they run at virtually the same speed and power input (~7 watts), yet the torque and hp on the eight coil unit is much greater for sure. Sorry I don't have prony brake numbers for you all. I put on on the eight coil model and it bounced to much to get a good reading.

The four to five times power mechanical power output is my best guess by comparing with trying to stop the eight coil motor from spinning with that of an AC fan that was rated at 45 watts...

Hi,
many thanks for posting this new video !
Looks very interesting !

How many amps do you get at the output into the bulb ?

Please try to use just a graetz full wave bridge rectifier at the output without
the caps and charge with these pulses directly a second battery and then
compare, if the second battery charges faster as the primary will discharge.

Then it will be simular to a Bedini system.

If you would still use the reed switch directly instead
of the transistor to pulse the primary coil, you will
probably get also a longer run time before the primary battery will discharge...

Mechanical switches are always better with coils and batteries energywise ,
due to the back current spark effect!

Many thanks.

Regards, Stefan.

Ian, your video is very impressive! Good work.
can you post a schematic?, How do you wound your coils? Is the Bolt of the coil made from Iron?

regards, Dani

It really is very simple. It is just a regular low grade steel bolt with the head ground from hex to round. The reed switch turns the transistor on and off. The coil is bi-filar wound(two wires). One wire for driving the rotor and the wire for taking the back emf off using a single reverse diode.

Thanks for your interest but this setup really is nothing special.

To answer your questions.

1) 120 ma from output side.. about 2 watts

2) I have not done that experiment with this motor. I made this for two reasons. A demo unit to show and compare the torque-power and input draw vs the output torque-power with my larger motor first discussed here. As you may notice, the input on both motors is the same. Yet the mechanical output on the one with more coils is considerably more. I don't plan on experimenting with this low watt demo model. The second reason i made it was to be able to show and explain to young people that are interested in this stuff.

3) Yes, mechanical switching is better. My other motor first posted here uses that. This little one was to low of an ohm rating to use these reed switches rated at one amp.

4) I am in the process of making a mechanical commutator for my eight coil motor. I have replaced the rotor with neo magnets and have added eight more coils as generator coils. This should be able to handle much more current... but I feel there is an inherent design flaw in the cores being a bit too small and not the best material, being just bolts, so i may oversaturate the cores too easily. But I should be able to get some real input vs. output numbers off this version.

Wow that sounds really great Ian,
Would be great to get some mechanical output measurements on your new setup when its finished.
Good work!
