This guy's company uses regular 3 phase cages. Here is what they do
A permanent magnet generator 5,5 kW 1500 rpm 220V It can be used for hydroelectric power. On small speeds, as in video, it produces up to 50 V. The grid tie inverter generates up to 120W. Our company produces generators with power from 500 W to 30 kW, speed 100 to 3000 rpm

Totally cogging free, well almost, we know better. Much better than the old way till she starts pullin a large load. It's a little better. You can order the rpm best for your project. Still way under unity.

This is how Jeff's rotor looks. The bearings are bigger and the whole thing operates at a lower speed. If you put one on a car for instance, you wouldn't need a 3 or 4 to 1 ratio like a Delco running at 6,000-8,000 rpm's. This one could do well at 1500 rpm's. This is much lower.

Dear Memphis and to the entire group.
I will say it again as I have so many different ways, the people showing excess energy from their motor generator schemes have modified the generator to low cogging. If you don't know Jeff at Missouri Wind and Solar I'll tell you he has been around for years developing a low cogging alternator.
The early video shows the original stator core and the updated video also of Jeff shows you how he won the battle. He has no problem sharing it because no one else can make the changes.
This new design has a greater efficiency. Low cogging stepper motors used this same approach.

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).
