  • Using JS monster driver on dual stator asym motors

    Hi Ufo ,

    As you may know I am gravitating toward dual stator motors. So I assume it may be pulsed in sequence just like the Quad stator motors, but simply alternate between brush sets. I have an Arduino, but I don't think I have seen a program posted for a dual stator. When I get that far, I have a copy of the quad blink program. Is there a link at your site where perhaps several of these programs may be available that have been posted? Picking thru various programs to find the options desired is usually helpful. But I bet Gary C. could whip one out in his sleep Time has come to get some monster drivers assembled ASAP!

    BTW Dave45 and Holbi are some sharp fellows!

    • dual stator program

      @Sampojo

      Hey Joe I am working on a throttle controlled program. It has already been written in a simplified form for Kogs. The RMC program provides for this although it is a more complicated program. At the top of the program just put in the number of brush pairs that you have on your motor. I have been busy with reworking my set up, and have not had enough time to test these programs as fully as I would like to. Hopefully towards the end of the week I will get a break. I have completed the all north wind for the goldmine motor and in my preliminary tests have mixed feelings about it. It does indeed accelerate under load when wired as ufo has it. Maybe my timing is off and so I want to play with the timing some more. Also like Kog's test on the Imperial it does not respond well under mechanical load when wired that way. It does extremely well with direct drive and I will test pulsing next and then post my results.

      Cheers

        Here R3, R9 come into play. They need to be tuned to be as low as possible and as high as to dampen oscillations. The value 1R is a place holder only. Some circuits need 5 Ohm others up to 47 Ohm. It can't be predicted.
        If you have no scope please use 22 Ohm or 33 Ohm and check for heat later on.
        If you own a scope you will start with 0Ohm (simple wire) and check for oscillations. Then you increase up to the state where you have no oscillations left. You will perform this test with resistive load i.e. a car headlamp connected to 12V. (see procedure below)
        Hello guys!
        I did my handpainted pcb of monster 5.1 (later on will buy from oshpark)
        and tried tuning.
        (i use signal generator with meandr,
        after opto the signal become weak and collapses at high frequency 460kHz,
        but after schmidt trigger, before micrel the signal is excelent up to 459kHz very good shape meandr(w/o load on drain/source))
        Still can't avoiding oscillation:
        Anybody, who succeded in this,please, advise; thanks in advance to UFOPolitics, Garry , you help much with my questions.
        So, questions about antioscillation resistors R3,R9, see pics(pic number and frequency in right bottom corner),
        - yellow probe - Source/Drain
        - Magenta - Source/Gate1
        -Blue - Source/Gate2
        with halogen lamp connected to 12V drain/source
        1. 10kHz, blue 10 Ohm, yellow 100 Ohm
        2.absolutly same oscillations with 60kHz
        3. same, but blue resistor disconnected from gate
        4.blue 10 Ohm and yellow 10 Ohm

        without load(lamp)
        5.gate signal good enaugh up to 230kHz
        6.gate signal 30kHz
        7.my bungling board

        i see, that the bigger the R3,R9- the less amplitude of drain/source oscillations, but more unshapely gate signal.
        in this circumstance i can't choose right resistor, because
        with 100 Ohm still oscillations, but gate signal almost breakdown.

            Hello Ufopolitics,

            Thank you for the suggestions related to the measurements.

            I did a 3D model for the minimalist redirect core that can be produced easy even at home for the testing.
            The material is soft iron with square cross-section 20mm×20mm. The central part of the core will be 40mm×40mm. This material is enough cheap and practically is available in every iron-store (~ $25 USD / 6 m strand).
            After cutting to the proper part sizes it can be warp in a vice even in cold state.



            Some other views:










            Important note: The North and the South part of symmetrically different parts to be able to connect them properly. If let we say, one of them left oriented, then the other pole should be right oriented. And when you will face them every part will contact properly.

            Here (in this picture) the central gap is 40 mm.
            To measure and define the right gap distance - as per suggestion of Ufopolitics - this core should be adjustable.
            The adjustment is available by putting placeholders between North and South part of the core inside of the green coil holders.
            For example it can be used
            4 pcs 2 mm high 20×20 placeholder made from too same soft iron with square cross-section 20mm×20mm or
            4 pcs 10 mm high or
            4 pcs 20 mm high etc.

            For the 40 mm gap was used in this model 4 pcs 36 mm high placeholder inside of the green coil holders.

                Hello Midaz,

                Thank you for the interesting.

                I had been involved in different scientific research and development projects since 2009 and all of these projects were used the different versions and components of SolidWorks CAD/CAE environment.
                It was easy to learn how to use SolidWorks (there are good tutorials in the system and many youtube videos), so I continued to use it for other purposes also.

                Some part of SolidWorks available for free download (mostly viewers).
                Free CAD Software Downloads from SolidWorks
                And the full system is available with big discount for students and educational institutions.
                You can read more here: Student Edition Software | SolidWorks

                The biggest advantage of this system is the complex CAD for the mechanical and the electric part of the design. Designers can place 3D versions of all electrical parts into their model, and run wires/cables/harnesses in 3D to connect all electrical equipment. This feature is a big big help in the everyday engineering work.

                Also important advantage is a possibility of several simulation.
                Electrical Design Packages | SolidWorks

                Disadvantages of the system:
                - Does not run under Linux;
                - Big dependency from the Microsoft software components as MS Excel, Visual Basic, etc.
                - This is an expensive commercial system for design engineering.

                I tried to use also SolidEdge 3D (by Siemens) but I like SolidWorks better.

                And of course I had experiences with different 2D CAD system since late 1980's but now I use only SolidWorks. If you can access to these system I recommend to learn how to use it. You should go through all of the tutorials and do all of the drills and you will expert of the system by days.

                Kindest regards:
                Holbi

                    @sawa25

                    Just curious sawa25, what are you trying to drive at those kinds of speeds. The monster driver was really designed to drive asymmetrical motors. I imagine it will perform pretty well at speeds far beyond the requirements of the motor but that does seem excessive for the original design parameters of the monster driver. JS has a pretty good description at the beginning of his book on the problem with FET's. There is built in forces in conflict with clean operation that are opposing each other. Capacitance and resistance that create oscillations in the operations of the gate. Read it and perhaps you can find better, faster FET's that will meet your needs on your project. The coolMos FET's are among the best. The price goes up considerably depending on the parameters that you are actually going to need for your project. i.e. more speed, less heat resistance are going to cost much more from your wallet. Find what you actually need for your project and then purchase the parts to fit those parameters, they all break down at some point.

                    Cheers

                    • More tests on UFO-Basic circuit

                      Hello Ufopolitics,

                      To get more experience on the Basic single coil UFO-circuit we did a series measurement.


                      Loads on the cold DC side were different resistance loads as a light bulb.
                      The electrolytic capacitor was 1 × 10.000 uF and later 2 × 10.000 uF parallel. There was not change in the performance with one or 2 electrolytic capacitor.

                      1.) The 1N41418 diodes appears too weak to this circuit. We burned 6 of them.
                      2.) NTE576 was not in our supply chain so we used STTH12R06 (Turbo 2 ultrafast high voltage rectifier) instead of it.
                      By the description:
                      The STTH12R06 uses ST Turbo 2 600V technology and is specially suited as a boost diode in continuous mode power factor corrections and hard switching conditions.
                      This device is also intended for use as a free wheeling diode in power supplies and other power switching applications.
                      This is a 600 V / 12 A / 25 ns fast switching diode in TO-220AC insulated package.
                      They were also burned in the both coil ends and in parallel with the switching transistor also.

                      The measured current in the coil was not to high, few ampere only when the diodes destroyed.

                      We change the 1N4148 to the 1N4007 (1000 V / 1 A / ??? switching time) and
                      STTH12R06 to the BY550 (1000 V / 5 A / 200 ns) and the circuit works well.

                      May the 1N4007 is not the best alternative of the 1N4148 but it works.

                      The energy balance of the single coil circuit is quite well using DC output and resistance load.

                      The output power measured on the light bulb with DC voltage and DC current was exact data.

                      The input power was measured by oscilloscope and counted from the graphical form of current impulse drown from the 24 and later 36 V battery.

                      The impulse frequency for the measurement was between 100 Hz and 800 Hz.
                      The duty cycle was between 50% and 15%.
                      The output power was between 5 W and 38 W.
                      The coefficient of performance (C.O.P.) depending from the frequency, duty cycle, power supply voltage, load resistance was between 2.5 and 6.0.

                      So, I can witness, even a single pulsed coil with the proper arrangement is possible in the small scale OU operation.

                      Regards,
                      Holbi

                        Excellent Testings Holbi!!

                        I just hope you filmed this testings so we could see them all!!

                        1.) The 1N41418 diodes appears too weak to this circuit. We burned 6 of them.
                        That Diode is there just to conduct readings at certain Low Pulses...if you go higher they will blow....it is a fast diode, but very low amps rate.


                        2.) NTE576 was not in our supply chain so we used STTH12R06 (Turbo 2 ultrafast high voltage rectifier) instead of it.

                        The measured current in the coil was not to high, few ampere only when the diodes destroyed.
                        They will burn because of the "Dual Currents" creates a super fast environment because of being opposite to each others...too high for many strong Rectifiers to stand.

                        We change the 1N4148 to the 1N4007 (1000 V / 1 A / ??? switching time) and
                        STTH12R06 to the BY550 (1000 V / 5 A / 200 ns) and the circuit works well.
                        Very glad You have found the right choice...

                        May the 1N4007 is not the best alternative of the 1N4148 but it works.
                        Well...if it works...don't touch that dial!...(American saying...means: leave it there, "as is" )

                        The energy balance of the single coil circuit is quite well using DC output and resistance load.

                        The output power measured on the light bulb with DC voltage and DC current was exact data.

                        Excellent!...actually we do not need much more voltages at input...

                        The impulse frequency for the measurement was between 100 Hz and 800 Hz.
                        THAT'S EXACTLY ALL WE NEED!...I have never written here, absolutely anything about Khz nor Mega Hertz anywhere!!


                        The duty cycle was between 50% and 15%.
                        The output power was between 5 W and 38 W.
                        The coefficient of performance (C.O.P.) depending from the frequency, duty cycle, power supply voltage, load resistance was between 2.5 and 6.0.

                        Excellent Holbi and Team...now, just for the record...because no one here knows we have been talking on private mails for a while...therefore they do not know who you guys are...and your credentials on this fields...

                        Please, I am NOT asking for ANY Personal Private Info from you...nor your real names nor locations...(Eastern Europe is just fine Holbi...)

                        On another note...and reviving the past of this Thread (I believe is very worth now)

                        A Single Coil is just the beginning of this whole deal...whenever we pulse a Coil (Looking at it from the Magnetic Field ONLY)...we create a "Magnetic Alignment" called a Field...that, is digested knowledge for many here for a very long time ago...what is new...is that by generating a magnetic field we are actually "aligning/invoking all kind of Aether Particles AROUND that Field, that stay there...just lingering...so, when we collapse our generated "artificially" field using Hot currents...we create a huge vacuum...that will "suck" with it all those outer aligned fields into our coils...and something I have called "A NEGATIVE INDUCTION" will take place in the same coil wires...traveling opposite to our collapsed flow.

                        Now, where exactly in Geometrical Terms...will our generated field go?...The answer is the very center of that coil...a point in space...that we could call the coil "Gravitational Point"...set exactly equidistant from each ends...each magnetic poles...that's where it will disappear completely like magic...so to that exact point is where our Radiant Field will go towards also...BUT, reversed polarity...why?...because of magnetic relations...a North will attract a South...and a South will attract a North...simple stuff right?...so where there was a North...a South Radiant Field would be...and so on for the South...

                        In Motors we have a disadvantage...when we deal with brushes...we must let that coil "go" without collecting till it reaches the next brush or output gates..

                        But in Static State...we don't have that problem...coils are not going anywhere...

                          I was graduated as electric engineer with a "summa cum laude" diploma and had a quite good background of mathematics and physics from different kind of students competitions, Olympiad etc., and had some non conventional electrical practical basics from different kind of self-made RF application but all this mainstream education is worthless to create a working free energy device.

                          A some time ago I decided to re-learn all basics starting from Faraday, Ampere, Maxwell and Tesla. And I suggest be humble and open, that there's so much more, that you can learn.

                          During this way I had realized even the electricity has not had a good working definition in "classical physics". Everybody are talking about electricity, everybody knows that electricity can shock somebody but what electricity really is? I did not find good definitions and descriptions.

                            • Hi Ufo,


                              I am using that setup as in the picture below for my 2e output but i am not using the caps inbetween.

                              And good to know those 1n4148 can be discarded ( correct? )

                              I can hook up load there to, but it steals some amps from my 1e output.

                              See here how i test my 2e output, and i am using high switching diodes HFA08TB60

                              From 6:34 in the movie im showing the test from that 2e output on a bulb, and my input does not change.

                              I just hope you filmed this testings so we could see them all!!



                              That Diode is there just to conduct readings at certain Low Pulses...if you go higher they will blow....it is a fast diode, but very low amps rate.




                              They will burn because of the "Dual Currents" creates a super fast environment because of being opposite to each others...too high for many strong Rectifiers to stand.



                              Very glad You have found the right choice...



                              Well...if it works...don't touch that dial!...(American saying...means: leave it there, "as is" )



                              Excellent!...actually we do not need much more voltages at input...



                              THAT'S EXACTLY ALL WE NEED!...I have never written here, absolutely anything about Khz nor Mega Hertz anywhere!!





                              Excellent Holbi and Team...now, just for the record...because no one here knows we have been talking on private mails for a while...therefore they do not know who you guys are...and your credentials on this fields...

                              Please, I am NOT asking for ANY Personal Private Info from you...nor your real names nor locations...(Eastern Europe is just fine Holbi...)

                              On another note...and reviving the past of this Thread (I believe is very worth now)

                              A Single Coil is just the beginning of this whole deal...whenever we pulse a Coil (Looking at it from the Magnetic Field ONLY)...we create a "Magnetic Alignment" called a Field...that, is digested knowledge for many here for a very long time ago...what is new...is that by generating a magnetic field we are actually "aligning/invoking all kind of Aether Particles AROUND that Field, that stay there...just lingering...so, when we collapse our generated "artificially" field using Hot currents...we create a huge vacuum...that will "suck" with it all those outer aligned fields into our coils...and something I have called "A NEGATIVE INDUCTION" will take place in the same coil wires...traveling opposite to our collapsed flow.

                              Now, where exactly in Geometrical Terms...will our generated field go?...The answer is the very center of that coil...a point in space...that we could call the coil "Gravitational Point"...set exactly equidistant from each ends...each magnetic poles...that's where it will disappear completely like magic...so to that exact point is where our Radiant Field will go towards also...BUT, reversed polarity...why?...because of magnetic relations...a North will attract a South...and a South will attract a North...simple stuff right?...so where there was a North...a South Radiant Field would be...and so on for the South...

                              In Motors we have a disadvantage...when we deal with brushes...we must let that coil "go" without collecting till it reaches the next brush or output gates..

                              But in Static State...we don't have that problem...coils are not going anywhere...


                              Regards Friend

                                Hi Sawa,
                                after long time I had some minutes left for watching this forum and found your setup. I am so sorry you did not read all my earlyer suggestions. Obviously you tried to contract the PCB size but that is not the clue.
                                Any leg of a component or mm of pcb wire performs as a cap, coil, resistor - small amount but present. In normal circuits it is of no importance but if dealing along fast components like FET and Micrel it fosters any unwanted oscillation. Sorry to say that I doubt you will get rid of those oscillations because you have lots of fine oscillating and parasitic tank circuits at your setup.
                                The layout of monster driver was optimized for through hole components and was set to a 1/10 " grid in order to build it on a perf board with thousands of holes and pads. Either you use my optimized layout or you build it on perf board.
                                BTW: The monster driver was built for low frequency and very steep power edges. For higher frequency the opto will not perform well. It needs to be replaced by a faster one. Apart that the driver was specifically built for high current. The reason for all this was to get the Imperial setup running. It is no novice device. And it is opto isolated for severe applications.
                                I strongly recommend to use all sorts of other circuits presented earlyier in this forum. Usually 555 along FET performs quite well.
                                Unfortunately my time does not allow for desinging a simple driver for you guys but please find some along proved functionality in this forum.
                                Sorry for all this :-) Do not feel discouraged! Take it as learning effect for future setups. Mistakes are no failures but chances!
