Hello, I have assembled this circuit for a 12V motor that commands one automatic chickens door, but when I press the button the relay does not remain hooked when I leave it, what can I do ?, I need your help. maybe I have to adjust the value of some resistance? thanks. The voltage from tampon battery ist 12-13V Ist OK?

Sir, will it be helpful to use 30v relay or a higher voltage than the 12v relay together with a higher potentiometer say 25k in order to obtain a higher output adjustable voltage say 30v above or above 24v?

A how-to book on a pragmatic use for a Shorted Motor is.gd/oupaperback Shorted motors and shorted transformers can easily get out hand and fry themselves. But, if regulated, can be a source of useful energy turning themselves into their own generator. I used Micro-Cap to design a motor wiring scheme which is shorted and prevented from reaching voltages and current levels beyond whatever value desired so as to convert a problem into an energy saving solution.

Thanks a lot for your insight.I will be very happy if you could give me your email Sir . I might then need your layout urgently.

i take it that black 6 legged ic is protection

@tatterdemalion898 5 жыл бұрын

yes it is, but not in the way you think. It is a dual op-amp setup. the dual op-amp is the IC. also there is a relay which is supposed to be on if all is well. The first op-amp is an amplifiewr and the second one is a comparator. With the potentiometer you can regulate the reference voltage, that the comparator uses to see if there is a short or not.
