Can’t wait to see the drone.
Nice effeciency even at low power. So, the design of you motor is just ... wonderfull!
Thank you. I hope soon i can go under much higher load, and to observe a even much better efficiency.
@@iulian207 hi，i just want cooperate with you
Thanks for going through all these details! Really great design and execution.
Your equipments are really impressive. Your projects equally impressive.
Thanks for sharing the setup and results. Impressive work, Iulian!
Very good dear Iulian friend!
WoW, so powerful. Congratulations.
very nice , this motor can power a car even a truck ,
Can we experiment this with motor cycles or cars out there on the roads?
Or is it too early?
Awesome, very quiet motors. Help me understand. The battery shows -9amps and the generator 20amps and the motor is only turning at 1,600 rpm, can you please tell me; how much many amps is the motor using? So if it is using less than 20amps and the generator is putting out 20amps then it is making more than it uses, correct?
Hi Rick, at 14:34 time, the power used by the red motor is 532W, the output electrical power produced by the generator is 430W. Do not get fulled by the amps only you need to compute the power. The overall efficiency of the motor combined with the efficiency of the generator and efficiency of the Vesc controller is 80% at 0.7% load. The red motor efficiency at only 0.7% load is 86%, this is an extremely good number. With a full load the efficiency of the red motor should go to 96,9-97%, making it the most efficient motor on the market for this power level.
Bună Iulian, cât costă un motor?
Hi Iulian.. what was the efficiency of the bldc motor as a generator?? In your video i guess i did not give the summary. Can u provide please??
If I have 35 kw brushless motor , what size of gasoline generator should I buy ? 35 kw gasoline generator ?
Is that Paul Holmes's controller? Nice!
Yes, we are collaborating
@@iulian207 This makes me extremely happy! :)
Did you test Pmax of these motors with this setup, looking to run a similar setup, Also have the datum sensor.
Hi, how much do the motors cost please and where did you buy them from?
How know why motor current(inverter out) and bat current(inverter in) are different??
Which generator is that and how many kw ?
what power output are each of your batterys
Hi bro I would like to know the specifications for 130 kw motor like poles and esc circuit
motorcycle kit for 800v 200Arms controller please
Very very impressive. I am trying to build an PMSM. Which could generate 16kW peak and 50Nm peak torque. Could u pls tell which software that you use to design? And also will u be able to support.
Oi amigo. Tem como passar o esquema elétrico e como fazermos motor bruslles
What do you think about 6 phase asynchronous motor where 3 phases are star and 3 are triangle? There is a controllable phase shift between those so it can have a constant high torque from 0 rpm. That is somewhat like russian Duyunov motor wheel works but he doesn't share the exact technology. Also can you build motor wheel which will fit standard wheel disk on top of the outrunner rotor?
I'm sure he could build one but i don't know if making a car with hub wheels actually makes sense. This would increase unsprung mass drastically.
Hi! Nice to see someone build such an amazing system on his own.
Could you please show a bit more of the electronics involved, talk about how the control is implemented and how you came up with the motor design? Also some constructive criticism : Please try to hold the camera a little more steady or use a tripod or something, its actually very difficult to watch and im not some old goober with motion sickness :D
In a few day i will make a new post on my blog with detailed description. Sorry for the video shaking, i will buy a better camera.
@@iulian207 Thanks, im very interested!
No need to buy a camera, the quality is allright, just maybe keep it pointing in one place for a bit longer, as a viewer its a little more difficult as we dont knwo what to expect in the next angle and it would be nice to have some time to adjust and see whats happening. Just a recommendation, other people may think differently than me ^^
@@iulian207 can I get on your blog? Please? I been working on a self running generator just for our home... and just for hot water and heat.. anything that runs at usa 220/240v. Everything else I would just run on the grid. But I cant seem to get a decent controller over here.
Could u sell me a set up to run a 10k or 15k 60 cycle generator full time
Great project iulian! If the motor is open source where can i get cad files??
Hi!! Boss for dc motor 7.5kw , 72V I wanna run that motor on 3 phase electricity, which converter will be good ? Second I wanna put capacitors pack for better polarity and efficiency? Please kindly help me that I don’t know much about electronics
can you loop it back ? battery to motor , motor to gen then gen to charge battery , any extra power than you can use ?
This is exactly what i did in the video
@@iulian207 do you have extra power? or just looping ?in = output because your setup is amazing so efficient it would make more power
@@EnergySeeker it is impossible to get extra power out and any one that tells you different is full of BS. The term you are speaking of is called over unity (produces more power than it consumes) it is impossible because everything has losses. Bearings, friction, etc etc, that is why it will never be possible. Plenty of people have claimed to have done it, but no one has ever successfully proven it. That's because there is always a cheat. It defies the laws of physics.
@@DodgyBrothersEngineering Still have yet to find anyone generating power at an eff over 50%.
is this home DIY things ..??????
I don't care about the rpm, SHOW US THE GENERATED CURRENT
AKA how to build a airplane at home 😂
Hi...
Respect for selfrespect,
Complaint to United distance Nations (Today known as UNs) about to secure lives, living life and rights of citizens of republic distance nations from monarch or emir containing distance nations those are united.
Defination of Nation:
A large body of people united by common descent, history, culture, or language, inhabiting a particular country or territory.
Without any security for work, It is not considered as domain work (work which is according to governmental procedure.).
Why satellite humen surveillance ( humen machine interface) of Mr.Suraj Murlidhar Pharande and its sensation to sensable brains and from bioterrorism ( COVID-19 coronavirus infection become as pandemic ?)
Machine humen interface satellite involved machinery operates voters also to vote.
Why peoples in the world are not United to fight against COVID-19 till it causes death?
Timely report to respective place to cheack status of complaint.
Donation of rights are worlds biggest crime (an action or omission which constitutes an offence and is punishable by law.)😀😀😀😇😭
Crime corrupts every things life.
Yours faithfully,
Mr. Suraj Murlidhar Pharande .
Respect for selfrespect.
Spread this message.
Take care to avoide and spread of pandemic COVID-19 coronavirus infection. Corona virus is not spreading through water such information I read but humen saliva contains 99.5% of water so use disinfectant in water to avoide COVID-19 coronavirus infection.
Respect for selfrespect,
My name is Mr.Suraj Murlidhar Pharande from Nimbut,Baramati,Pune,Maharastra,Citizen dependent India.
You well known about me as satellite humen surveillance and its sensation to sensable brains as like you.
Write application to IHRC or such organisation which gives relief from such satellite torture to me and you also. If possible then give news about surveillance and its sensation to sensable brains in the world.
First secure yourself before messaging to another peoples.
Spread this message to other peoples.
I know what is tomorrow for this crime?, They make some laws and restrictions to others for satellite use and maintain there position as like today to do such crime again.
From childhood I am not known about what happens with my brain but at starting of teenage and at the 21st year of my life they try to kill me to show you peoples as these things are happened here but these things when I saw on TV as they show me surveillance is going on and every humen sensable brain in the world sense it, but this time span is too and no government or peoples complaint against so it stay on but my starting days of teenage too much torture were done by these peoples I felt in exam which causes my educational failure.
I don't have right to fullfill my sex need (as it requires partner or I see on internet pornography they impaired my digestion also brain functioning.) At age of 21 in college they do such things with me by satellite and one girl from thers community come to ask about marriage then they try to kill me as I drink insecticide after that I complete my master degree they again harash me at college and after completion of degree course I run for job and simultaneously for marriage I register my name at mali marriage beuro then I contact with girls and there's parents some positive response I got about marriage in that days I write about surveillance to get relief to NHRC,IHRC and various Presidents and prime ministers of various countries but again they try to kill me but this time they broke my hand and head by 4 persons and admit at mental hospital for six months out of them three months I stay in my house but tablets by force and satellite torture they feed me (by black mailing again we will admit you at mental hospital).
Today, Neuro phones sound and show name and photo of Mr.Sharad Pawar and his family members and give warn like past we will kill you.
Because I write about reservation for member of parliament of citizen dependent India and legislative assembly of state for every category that gives for every five years new respective candidate from every community possible and better regulation as they secure my living life (of every citizen other than elected members) from these elected members.
If Monarch ( supreme powers has single monarch onely) having nation or republic nation supreme powers both have peoples and elected representatives also If these type of two Nations are working together use or safety for that work (and representatives) gain onely by monarch having nation while elected representatives get changed after respective period so efforts and money invested is more of these peoples while assurance of work completion is not there (wastage) but that monarch can interfere with regulatory affairs of republic nation (People's know why representatives newly elected is necessary, for regulation onely.) as today.
Whole this directs to create a social hindrance for those peoples who are not in theres fever to use there rights govern by government and always fight to represent (To stay with they without any means of living life I.e.onely life.).Divine power gives meaning about rights of living life onely thers genes have while others are retainers or slaves (others are alive because of there means onely) for they.
Timely report to respective place to cheack status of complaint.
