Small Coil Pulse Motor
Вставка
- Опубліковано 4 лип 2022
- This is a simple electric motor inspired by Grandad. I reduced the electromagnet to a simple minimum turn small coil. I was able to drop the amp draw by adding a small 3 ohm filament light bulb in series with the coil. A simple reed switch worked fine with as little as 1.5v. The amp draw is still very high but the reed switch alone could handle it with out adding a transistor.

Interesting twist using the filament light bulb 💡 🤔 👍
That filament bulb worked great. It not only dropped the amp draw but it also made a wonderful pulse indicator.
I've had the same high current and heating issue with one of my projects. Going to have a play with this idea, thanks.
Hey bud, Slider2732 here. I got locked out of YT when we moved house, which is kinda ironic.
This bulb behavior is in line with Bedini's systems, his 'ear of wheat' bulb. Had good success with that some years ago and it's fascinating to see such a practical use with the supercap. A similar thing happens with wireless transfer, when not wishing to blow up receiving circuits. Add an LED in series and it'll brighten and dim automagically with distance and load. Great vid!
Hi. Sorry to hear about the YT problem with your channel. Your right about the Bedini connection with this filament bulb usage. It was an important tuning part in his SSG circuit. I am still scratching my head about what I have just done here. This should work with an LED also if the voltage is right. Somewhere between 2.5v and 4.5v with the right coil should do it.
That is awesome and very smart to use that current limiting bulb.
That wire is probably 18 or 22 gauge solid core wire. sometimes called "Bell Wire" (used for doorbells)
Fascinating.
Yes it is.
Top very good!.
Thanks.
So do you think you're getting flyback from that small coil along with a pulsed bulb allowing for the 15min run time ? Would the flyback go straight back to the cap or does it pass through the bulb and reed switch ?
oh! the lightbulb acts like a resistor and the discharge time Tau=R*C !
Did you make the Reed switch from scratch?
Hi, for us less knowledgeable, can you 1. Stop the motor so we can see the wheel and other parts. 2. Provide schematics.
Maybe later. It is a simple 'reed switch' pulse motor circuit with 4 small N facing neo magnets on a plastic jar lid for the rotor. A large sewing needle running in a brass screw is the main bearing.
Share me this circuit thanks
May be, will be better bifilar Tesla?
YES! I am sure that this will work with a small pancake bifilar Tesla coil. Great Idea.
