  • Monster driver board death in AMC

    Things looking up, only one mosfet looks bad. Had to isolate the mosfets to find out if only one was bad, so I had a 50-50 chance and even this squirrel found a nut, first try got the right one. As soon as I took the bad board out, of the shared ground, the other one started working, too. And I am using a new soldering bit and now I have plenty of power to work on the 12ga wire on my 100w iron. Planning ways to squeeze in 4 mosfets per board, as Dana suggested

    • Hold Tight - new MOSFET on the way

      Hello All,
      This might be just what we may need to deal with temperature and losses on MOSFET and allow faster switching. New SiC MOSFET in the making.

      • woo-hooo great results with AMC and unipolar motor

        Very preliminary. Got my AMC fired up finally. I had a gremlin running around the mosfets on one board, seemed to have a bad one after I converted my boards to quad-mosfet construction. It was on the board that I used Kog's method of going to the terminal from the heat sink. This has a great trouble shooting advantage as you can simply disconnect each mosfet and isolate it without having to unsolder!!! Slowly started disconnecting the Mosfets, seemed to detect a fault once but then could not. When first connected this channel would run the motor even when the Arduino was not pulsing. slapped things backed together taking some shortcuts to test the board, had to assume it was gonna work, and it did!!

        So here are my results. When pulsing, probably around 1KC at full on, my GM window double rotor dual stator unipolar winding did about 3450 rpm. I need a more sensitve ammeter, cause it was like it wasn't even flinching. when run as direct feed it takes at least 1.0+ amps. I ran it direct feed both brush sets, and got about 100rpm more. Close enough to compare for now! So it didn't even want to register 1 tick (1/2 amp) on the AMC and direct feed I know it takes about an amp.

        Standby as I will measure this up, down and sideways in the next few days.

        EDIT bad idea trying to make any deductions from a meter on the low end out of range for the job... It seems to stick sometimes I see today. found the bad mosfet from originals on the board now also. failed at a 50ohm short, not completely shorted yet...

        • recommendation for my1016

          Hello, I've been looking at something for my1016 but not cleared me, recommend me something to make it free energy or radiant energy that is easy to do for someone with no knowledge of electronics like me, if there is a circuit that can do that no amount taking oscillator or more complicated things, I want to to put it on my scooter and to travel many kilometers or go to school. any solution that can give me? do not laugh.

          • AMC update: Testing Power gains of AMC the goal

            My quad mosfet design runs super cool, no detectable heating with the motor on a 12v power supply. My main goal in this is to achieve the radiant energy gains promised by synchronous pulsing delivered by using the arduino with JS Monster Drivers. So the question is how could these energy gains be verified. I have been comparing a conventional pulse width modulator motor driver to my AMC and have some preliminary results.

            The test is simple:
            1. Run the AMC at max power (using 12v power suppy)
            2. Record total amperes
            3. Hook up the motor to a conventional PWM
            4. Run at the same RPM
            5. Record total amperes

            RESULTS:My unipolar GM window motor draws about 1.1A on the conventional PWM and about .08A less on the AMC.

            I do not get a big swing in amperage, it jumps up near an amp just to rotate, and peaking at the above values at the AMC max. The PWM max actually delivers more RPM. And straight from the power supply gets the most RPM. Since the voltage is pulsed, I plan to look for an average voltage value for the duty cycle potentiometer position.

            I am concerned that I am measuring such a small amount of difference. I will work towards a video. As for now, I have fried my PWM and a new one is on order.

            • Hello!

              Hello all,

              I know I am a bit late to the party, but I was hoping someone would be able to post an image of the original circuit that I could start working from. Preferably, the one referenced on post #126 with the polarities corrected. I have read a lot of the posts and the images seem to be missing from the start of the thread, so I would appreciate if someone would be able to help me out.

              Thanks,

                Hello Tony,

                Ok, if you look at the post I have made after, or #127 here

                You could see the simplest controller built with the 555 timer, and schematics are here
                And here from my albums with more FET's:

                [IMG][/IMG]

                I made a more complex circuit by adding a voltage regulator (LM317) to use it with higher voltage than 12V (36V) , plus more MOSFET's (they are all N-Channels) connected in parallel to stand higher pulsing amps, as shown below:

                [IMG][/IMG]

                And below is a detailed zoomed view of the LM317 Voltage regulator correct circuit and components.

                  • conventional PWM performance vs Arduino/Monster driver

                    I had run a quick comparison on my GM window asym motor series I have built and on the ragged end of detection I thought I saw a 7% improvement in performance (dual stator). I haven't been able to conduct any more significant testing because my motor seems to keep burning up my conventional PWM controllers. This kind of reminds me of John Stone saying many time how the monster driver boards were designed to withstand all the bemf effects of these motors while conventional designs would be insufficient. So true it seems... As for my neon radiant energy detection circuits I have built in on my AMC I can verify they work, as when running it on my asym motors, I can see them flicker dully when I turn down the lights I think I will have to build a new program to have my AMC function as a conventional PWM in order to nail down the performance of pulsing brushsets synchronously vs conventionally. The effects are supposed to be stronger on a quad stator asym motor and that is still in the works, as my first design ran way too hot.

                      You are still banging away at the JS Monster and AMCs.
                      synchronously vs conventionally... Off hand, what differences could there be? Can you post a vid or pic of your conventional controller?

                      You had heating in the past then improvements. Are the motors North/South wind or all north groups or pairs? Which design did you use for each tests?

                        Hey Midaz,

                        The deal is if you pulse each brush set in a synchronous order, its supposed to release more Radiant Energy, as opposed to the way a conventional PWM would pulse each brush set under power at the same time, or a battery in direct feed. I wound a unipolar quad stator of mine recently but was off on the resistance and haven't gotten around to rewind it. I am trying to operate on motors in the 5A and under range. I have burnt up a couple cheap motor controllers so I am thinking things John Stone had posted about all the RE running around needs a lot of heavy duty components. I plan to make a program running the AMC as a conventional PWM to test things out. Still need to build some more monster driver boards. I was out of work for a few months for an operation and during recover hacked away at this stuff. Not so much time any more back on the job. Working on the unipolar designs. Got a Quad Pentagon Bent Y 10 pole, which is a N-S Winding to compare to, but it also runs hot, with too low a coil resistance, so if I build a good unipolar motor, they may be tough to compare since the wire gauge ratings will necessarily be different. I am leaning toward multifilar windings too.

                          For hot coils, are you thinking about using thicker wires with less turns or thinner with more turns?

                          • hot coils question

                            I have gotten alot of input from Prochiro on how to get them most out of a rotor. and of course Ufo has stated a coil must come in around one ohm resistance. I try to fill up the rotor to get the most out of it. Using multifilar complicates the calculation but I am getting better at it. It gives you options. My motor was hot-running bc I made the wire thicker by going to 4 strands and I went longer since the rotor wasnt filling up on my first winding at 3 strands. But I ran out of room making the coil length shorter than I should and was coming in at around .7 ohms per coil when it was fully wound. My solution here is to go back to 3 strands and go longer, targetting about 1.33 ohms per coil to allow it run continuously and get no hotter than 120 degrees on 12v. I already have a dual stator motor of this type that is wound at around 1.3 ohms per coil, and that is how it runs. That is hot to the touch and I worry about it. I have this really good wiring guide that breaks down the resistance every which way, and since I don't have good multimeters, I am going strictly by calculation. So on this wiring guide, you may find what I am using, 32ga, 6' per ohm, and 3 strands at 24' will give 1.33 ohms. Perfecto! This will go far to filling up my rotor. I probably should do prochiro's calculation, estimating the area of the inter-pole spacing and dividing by the strand area to find out how many winds it will take to fill them...

                            I had been watching Ufo's vid on the imperial epic run, on the MAEM thread post 3132. And I just recently noticed one temp reading was 160+ degrees at the end of the run!!! Looks like the brushes. My question is, How hot should the motors be allowed to get? My little motors above, the whole motor will get to be 120 deg+ including the magnets. So not only do you have to worry about melting something, but also about the magnets overheating and losing their magnetism. Do you have a temp gauge? How hot is the A1-MoGen getting?

                                This thing has nothing to do with Cold electricity, or "SHE" as some have called it.
                                Oh master of masters!!......please, (we beg to your 'Honor') let Us know all what Cold Electricity really is?

                                You would not supposed to misleading people.
                                But explain what it actually is. Certainly not the Cold electric, for sure.
                                Why don't you, master of masters, explain to ALL of Us...naive people, what Cold Electricity, Radiant Energy is...before you keep judging...

                                As what yours Intentions are. But that might have effect to reject a lot of naive, who participate in this game.
                                Please reed more on the subject, what cold electricity is, and how it behaves.
                                You are judging and criticizing is NOT CE nor RE, SO it is completely on YOUR END to speak up and demonstrate what really is.

                                Unfortunately, practical applications, are not available to the public. as far as known so far.
                                OH!!...applications are not 'available' to "public"?!...

                                Also, what efficiency of this setup is? How much energy you put in, and how much you get of of it.
                                Why you need so great amperages, when cold electricity can supply great power thru some tine wires,
                                for example.
                                Some have said "there is not such thing as pure cold appliancis" , I think that is description of this setup.
                                If some have had produced more power, or wast power, out of 36VDC, please report it,Anonymously ,thru
                                the network of servers, so no agency can track it.
                                Have YOU done ANY of all this Experiments so far?...all you did was "read"...in a language you do not "master".

                                This is some kind of an unconventional approach to energy.So is P.J. Kelly put it in his book.
                                But anyone can see that there is some kind of reserve towards it.

                                ps.

                                You are not only 'grammatically' incorrect, but your paragraphs do not make sense, they do not complete the "idea" about what you are "trying" to say ...everyone who read you, must keep "guessing" what you are intending to express.

                                Do You really expect that by just 'reading' here (no matter how long it took you to accomplish that) grant you the right to come here and judge, criticize plus insult, calling Us all "naive", misleading people, etc,etc...?

                                Back up all your 'judgement calls' with real examples, cite them, bring literature that back up all you are saying...show your expertise in the fields...etc,etc...only then you will offer some 'respect' for yourself.


                                Use -at least- a little bit of Scientific approach with your words.
