In this video, by changing the structure of the coil in the rotor of a DC motor, we turn it into a low-speed generator, and this generator can be used as a battery charger in small wind power plants.
And of course if you use a bigger DC motor you get more power.
This method is very cheap and simple and you don't need to buy expensive generators anymore.
Also, with this method, you can design and build it at any RPM you need
Very informative, One of the best modifications of a motor to a DC Generator, Accurate, and well displayed video. Thank you.
Very welcome
Thanks for the explanation and showing us that clever modification. One thing I would like to see is the electrical resistance of the coils before and after. Something always desired is that it be as low as possible to reduce inefficiencies. When the resistance is high the torque needed to rotate the shaft is higher to maintain a given power output. In the case that it is used as an electrical generator it would imply larger blades. Your video has suggested me to transform this stator into a three phase stator with neodymium magnets in the external rotor.
Good luck
The output power of this DC generator does not change at all, all we have done is increase the voltage with a slow rotation
If you use arc shaped neodymium magnet from N42 to N50, the power of the generator will be very high.
Thank you for your good comment
All the best wishes ❤
Also for you
Great video. Looking forward to see you construct the wind turbine
Thank you, but I am currently working on steam turbines and will definitely do so in the future
Thanks you so much. Great Vi!deo tutorial.
You are welcome!
Congratulations, I've been watching your videos and they're very good, they give me ideas to do new projects on my channel, you've gained another subscriber and you have my like
excellent
I also subscribed to your channel
Good luck
Sir very nice informative videos ☺️
Sir I have one confusion about coil winding. Original motor winding has two stars and two ends coil exactly 180 degree of armature point. But your rewinding of motor coil has one start point and continue winding with different stacks to end winding.
Can you please tell me which is right way to wind a coil?
Thank you for your nice comment
In the video, I have explained that in the machine method, we have to have two points of connection
But in the manual method there is no need for two connection points and in fact both methods are the same
If you want, watch the video carefully
For charging a battery you need more amps than volts a 12v battery will charge at 14.5v but you need as many amps as possible up to 60amps a 33amp hour battery will take 1.8 hours to charge at 60 amps. If it was 5 amps it would take 6.6 hours to charge batteries can take high amps but not high volts they will boil at 17 to 18 volts regards Graham Flowers MEng
thank you
In fact, the right voltage can charge the battery
If the amount of current is low, the charging time is long
And if the amount of current is high, charging happens faster
And the best voltage for automatic charging of a 12 volt lead acid battery is 13.5 volts
And in this case the battery will have a very long life
Of course, I have been working with lead acid batteries for almost 20 years and it is a great experience

Can you explain why it is that your multimeter reads are all in the negative. And, I take it that it doesn't matter if you turn/run the stator in a clockwise direction or a counterclockwise direction. Is That correct? Also, when you were winding the stator, was that one continues wind for the whole stator?
Thank you for your comment
Because the current is DC, if we change the poles, the negative becomes positive, and this is not so important, and the important thing is the amount of voltage or current that is shown.
As for rotation, it doesn't matter which direction it rotates, only the positive pole becomes negative
To twist the wire, we continue the same method for the entire commutator until we reach the starting point
@@fixedfocussolar Stupendous, my man. Thank You so much. I have to look over your vid again because I'm not that familiar on how to calculate what you did. Thanks again.

@@robinhooper7702take a DC motor, test it's voltage when it's going around 300 rpm (depends on how fast your wind turbine will spin is an average wind) take that voltage and multiply it till it's around 15 volts. So if the original was 3 volts multiply 3×5 to get 15. Next unwind one of the coils and count how many turns and record where the coil was and what comutator clips it's connected to. If the original coil had 10 turns to achieve 3 volts you need 5 times the turns to achieve 5 times the original voltage so original was 10 turns to make 3 volts so you need 50 turns to make 15 volts. These numbers change but the math stays the same.
1 find your wind turbines rpms
2 find your motors voltage at that rpm
3 multiply that voltage till it averages 14-16 volts
4 unwind the motor and count the turns that made the original voltage
5 multiply the number of turns to achieve the wanted voltage
6 do it to it
This works with ac motors as well
the required rpm for 12 v is too high..the wind max is 400 rpm..unless with the gearbox which is not easy to find
It depends on the type of use your transmission is using for torque converter
the wind cant spin it to 15 rotations per second though ? so //////
It depends on the location of use and the power of the wind turbine and the incremental gearbox
The only problem i see is you did not insolate the coil wires from the rotor
Well done to you
But I said in the video that the core has a glaze color and does not need insulation
@@fixedfocussolar I've wound coils experimenting and never found that glaze was adequate not all thee time,
Soon as it heats up.
