    You should not take advice from someone who wrote the post quoted above. It is so wrong. Beware of what BM tells you and what/who he recommends.

    I just recommended Peter Lindemann's attraction motor secret which you seem to have a problem understanding. Lindemann is a genius and you? Well never mind we won't go there.

    Let me repeat- the video teaches us some history on how to run a motor more efficiently than regular engines can.

    Motors, engines, whatever you want to call it

    I will say it again like this, the video teaches us all to run an electrical motor for 85% cheaper.
    Think of it like this, we know from the books 1hp=750watts and regular motor are only 80% efficient or they loose 20% of 750watts so a 1 hp electrical motor uses 600watts and looses 150watts.

    The video teaches us that the same 1hp motor uses 600watts but does not waste but instead recover 85% of the 600watts which = 510watts returns. So a 1 hp motor only takes 90watts instead of 600watts.

    That is a big deal.

    Now to answer your question you may gain 10% by pulsing the DC but that flywheel should give you 200%

    Dear mikey, the system already works, because the alternator disassembled in the picture gives me the necessary current, and the system runs because there is a 24v brush-less direct current motor mounted on the side on the right that makes the whole rotate . The problem is that the engine absorbs more than the alternator produces (in fact there are batteries connected), so I wanted a circuit that would allow me to power this engine with pulses, and therefore look for the best combination of the length of impulse, to see if it is possible in this way to produce more than what is consumed. Thank you for the video, I was already watching it on youtube, but being long enough and in English, for me, as an Italian, it takes time to understand it, but I'm trying to complete it to understand its explanation, thanks always for your kindness and availability.

    Motor windings need a sinewave. Using pulsed DC this Chinese scooter controller does this. Memphis you don't have a 3 phase motor with hall. You don't have a DC motor of a conventional design either....

    You must have a target speed. Current is controller like this........

    THE first step for you is to add a small timing wheel to the shaft with tiny magnets. I used an aluminum hub for $5 plus some 1/4 thick plastic disc about 3" DIa.

    your design will never self start, you will need to push it by hand in the direction you desire.

    but my problem is not the alternator that works very well, but I just need a circuit that sends me the current to the 24v brushless direct current motor that pulses the flywheel, therefore an adjustable pulse current, not a regulator speed which in this case would act on the supply voltage (being a DC motor).

    Hey Memphis

    Here is a simple circuit that Doc Peter L. runs thru the connections, however you can buy scooter controllers that have the extra wires for hall or reed for a brushless motor.

    For now look at this short informational video to understand your specific situation.

    Hi Memphis
    Looks like it is a 24vdc golf cart motor so it is like a universal motor some call "series wound" especially since you had to remove brushes and add magnets so everything I said about universal motors apply. By removing the commutator action with it's windings in series with the outside windings you have eliminated the timing for which the motor coils fire. Therefore you will need a circuit that fires pulses based on a sensor you will need to place on the shaft.

    Did you see my earlier post of Peter Lindemann's simple / effective circuit for a universal motor? His little circuit does the pulsing using a magnetic reed switch plus recovers all of the collapsing field energy back to an extra battery. You could use a hall effects switch also.

    Here it is and how when taking out the rotor you hook the 2 outside windings

    Mikey what you see disassembled is the three-phase 24v alternator of a bulldozer to which I replaced the rotor winding with magnets (so I also eliminated the brushes and the control circuit, now the output varies according to the speed of rotation, at 2500 rpm it takes out 42V.) The motor is the black one you see mounted in the photos on the right, it is a 24V, 500watt direct current.Now I need to power that pulse engine.Thanks always for the help.

    Here is one with magnets modified rotor and controller same as your 3 phase motor same as a 3 phase alternator with the rectifier removed. Everybody is doing this, this is nothing new. It works well from what I hear. You do not have a universal motor, you had a 3 phase motor that you have converted to a 3 phase DC brushless PMM ( PMM = permanent magnet motor) this is a winner.

    If your motor is 220v you might be in trouble finding a controller for high voltage. I have seen up to 90vdc.

    Notation: disregard all entries about universal motor controllers.

    Watch him, he shows you what buy and how to wire it up with a common brushless controller off of Ebay or Amazon.

    If this is your motor then it is a 3 phase motor. You can easily buy off the shelf ESC controller to run this motor. It is identical to a car alternator with the exception that there is no bridge rectifier.
