Running harddisk / stepper / brushless motor with stingo

[sucahyo]

This thread is about implementation of stingo spesifically for brushless motor.


Stingo can be use to run brushless motor by using available wire terminal. There is no rule of which terminal should connect to which part in the circuit. But some wire combination may not run or only run to spesific direction. Some wire combination will allow the motor run to both direction.

The motor may need to be pushed before it can run.

YouTube - Stingo Bedini stepper

While previous video show that it can run stepper, it is not the best operation for stingo. The best implementation for stingo is for bipolar motor like computer fan.


Edit: What this video show is not standard Bedini Fan circuit. While Stingo provide 6 times improvement over joule thief like Fan, it give similar performance to Standard Bedini Fan.

The top one is the one being used to run the harddisk and stepper motor. For Bedini fan application, you may need to reverse the second winding in case you converting from standard bedini fan circuit. If you start fresh, you may not need to create additional terminal. Try stingo with available terminal first.

I think, it's a good idea to create new thread... i like your simple circuit, material and the result of efficiency... payah pak ngomong inggris... aku ada nulis di blog bpk... pokoke maju terus... buktikan merahmu ! dan klo bisa, tolonglah kami2 yang buta elektronik ini dibuatkan spt imhotep berseri dari perakitan hdd, sirkuit... jadi listrik di rumah bs hemat, mana mati lampu terus nih.. ok good luck !

Thanks for the support .


Ok, maju terus , sayangnya untuk sementara belum bisa memberi alternatif kalau lampu mati. Sementara hanya bisa menawarkan informasi bahwa:
- untuk emergency light lebih baik pakai baterei basah
- charging pakai radiant charger seperti stingo dengan FWBR memperpanjang umur baterai
- untuk lampu bisa menggunakan LED. Rangkaian bisa pakai joule thief atau stingo yang dinyalakan dengan bateri 3V. Kalau pakai joule thief LEDnya di seri, kalau pakai stingo LEDnya di paralel.

Harddisk motor as charger

Here is a harddisk motor being utilized as part of radiant charger. It charge better than my 555 version.

more simple version

Here is a version that can use only two terminal. Unfortunately I can only make it work on 3 terminal stepper motor just like my harddisk.

The circuit include charger, but I doubt it would be radiant:

thank's for your information and support, i am just a beginner, trying to make my first bedini monopole and imhotep fan at this time, but unsuccessfull , i will use your circuit later with my bedini hard-drive and stingo, btw can i use 1N4002 for 1N4001/ecg125 ? trimpot 2-5K instead of potentiometers ? and 220 vac bulb ? it's hard to find any component in my city (south sumatera) thank you and good luck...

P.S. sorry, my English not good , if you do not understand, i will post at your blog.

Don't worry, your english is good enough for me .

If you use stingo for imhotep fan, you may not need to add terminal so it is easier to do.

If you don't use it for charging any working diode is fine. For implementation use at least 2Amp diode. I get mine from broken power supply. for potentiometer, at least use 5K.

What that 200VAC light bulb for? neon bulb should be easy to get on most electronic store.

[SiNagaPutra]

220 vac neon bulb, instead of 110 vac as describe in imhotep-fan schematic for protect transistor...
I am intend to use for charging lead acid battery.

I never notice such rating. To be sure, here is what I use:



If it lit then my output exceed 70V. I once measure more than 400V with it attached.


With under 500mA input, I never bother to use it. It can reduce output too. My transistor survive as long as I don't play with spark.

PS: Jangan pasang / lepas baterai selagi rangkaiannya nyala.

Ok thank u...

PS. Pelan.2 dicoba lagi pak, sambil belajar, nanti klo sukses sy baru ganti dengan stingo

Holly molly ! Isn't that interesting ? what is so strong with spark ?

[Jesus M NIeves Oliveras]

Hi!

The only problem for a newbie like me is to know where to exactly connect the hardisk motor to the circuit.

I see that the circuit is closed and has no label as to where to connect.

I only notice spark problem with stingo, especially spark on primary. I once try to up my output power to try to get consistent spark on the primary, don't try this:


I damage some fans connected to the same power with this arrangement. Aside from jamming mouse and keyboard, it also make my moniter screen goes dark entirely and make some clicking noise. After my monitor giving out, I gave up trying.

The only problem for a newbie like me is to know where to exactly connect the hardisk motor to the circuit.

Just connect it and see if it can run. I only remove the board and the disc cover.

You should see some terminal in the motor. Just connect it randomly and spin the disk on both direction. If it still do not turn, swap a wire. I can make it run at the first try. There is the optimum connection that can spin it fastest but I found most connection will work.

Edit:
Potentiometer position matter. I usually use about 10% to 25% out of my 10K potentiometer.

@sucahyo

Is this connection correct?

I am sorry I should have draw the actual disk picture instead of coil.

The coil in the circuit represent wire in the disk motor. So it is actually:


It shown to be connected to left most and right most, but you can use any terminal.

I will post the actual connection of the first version too.
