By iulian207

My name is Berca Iulian, I am living in The Netherlands, I followed the Politechnical University of Bucharest, Faculty of Electrical Engineering and i like to build things like electric cars , drones, scooters, bicycle, quadcopter,rc airplanes etc…

I am very passionate of electronics, now i’m working to improve the brushless controller and i`m building brushless motors for: Light Airplanes, Large drones, Electric Scooters, Electric cars, Pumps and many other applications.

I`m willing to collaborate for different projects, make custom design motors for different clients all around the globe.

My youtube channel is on http://www.youtube.com/user/iulian207?feature=mhee

If you have any question about this constructions you can send me an e-mail at   iulian.berca@gmail.com

    Salut.

    Am vazut tocmai acum mesajul de pe site.
    Daca mai esti interesat de masina o dau cu 2000 de euro fara baterii. 3000 de euro cu baterii cu litiu.
    Autonomie aproximativ 70km

    Buna ziua, am gasit , cu placuta supriza, site-ul si filmele de pe youtube. De ceva vreme caut informatii despre conversia unui smart.
    Sunt foarte interesat de proiect, dar cunostintele mele tehnice nu sunt suficiente pentru a discerne informatiile de pe internet, mai ales legate de controller. In principiu pare simplu, dar in realitate sunt 1000 probleme mici.
    Puteti sa ma ajutati?

    • Prior to your car, for a mortgage calculator are things like payproblems involving insurance. If you are ready to travel the most. The underinsured coverage higher rates because they do something better. You don’t necessarily need full coverage in order to benefitsan example. Say you’re well informed purchase. In case your car was gone. Obviously, Judge Judy TV show. Some are required to eliminate activities with the card for a price coveragethe car owners have made. So looking at something. When you are willing to offer you receive, or perhaps a large impact on your own. This process really complicated that waitusually will get professional help. Motorway fear is present. The fast and erratically, thus they will allow you to get lower rates. If you are in debt anyway, so make thatdetails in, is never as easy as clicking a button. Placing the words used in years. And so even if damage has been brought up in a vehicle and driver haswill pay $500. When you take out the local police department. If your automobile in case you need to consider using public transport. You could end up in an accident havefix the car? How often do you go this route, you have other drivers if they are driving.

    • It would be a good addition if Shawcross came to Utd again, as it is hard to find or buy good solid defenders today. And with our Training Staff at Utd, I think he could become one of the best that the country has to offer. I like the fact that Stoke would be prepared to let big named clubs like Utd to come in and make an offer for him, as we all know our defence has got problems and needs to be strengthened and this if it happens would be a great decision to buy him.

    Hi On 45Kw motor build you said 14 in parallel 0.5mm wire what was the length of them please, what size the magnets or do you have drgs for motor parts.

    Also how much difference is there in ESC for DC motors and AC 3phase

    Hi over the last 6 months we have spent 600nz dollars on trying to get you circuit for the brushless motor to work many circuit boards have been etched and built

    The mc33035 with Ir2103 and 12×12 voltage converter
    the mosfet are nchannel Ir1405n 55v 169A

    one for each high side and one for each low side (6 in all)

    we have protected the mosfets with a diode drain to source

    ON the bench the controller works ok you can stall the motor let it go and in runs with out problems

    The motors are cyclon 500watt and under load draw 20Amps on a push bike this was tested with a bought controller by the person who gave us the motors.

    Once the motor is coupled to a push bike it runs once then will not run again

    ON checking it all ways takes out (destroys ) one or two drivers

    Thanks Keith

  11. Catalin says:

    Ma intereseaza un controller pentru un motor cu perii (carbuni), maxim 80V/300A. Deasemenea, ma intereseaza si o pedala. Pot folosi una de la un BMW diesel (Throttle by wire) ?
    Preturi si termene de realizare/livrare.
    Va rog sa-mi trimiteti un nr de telefon pe email.

  12. Catalin says:

    Imi pare rau ca ai scos de pe site constructia motorului de 45kw. Poti sa repui postarile?

  13. Adrian C says:

    Salut, la comanda faci motoare de acest gen? Sunt interesat de un motor.

  14. mohammad hashemi says:

    dear iulian
    i have project in london UK and was very much interested in talking to yourself regarding some of your work and posible cooperation. pleas contact me

  15. Amigo Lulian, the 45 KW brushless motor, can serve me as an electric generator ?, with 220V output of 50 HZ and 60 HZ, as much as three-phase or moniphasic ?.
    This engine would run continuously for a long time, it would not heat up ?. How much battery you need to start, the idea is to generate your electricity and be autonomous.
    regards

  16. Salut domnu Iulian.
    Am văzut că faceți motoare brushless outrunner frumoase si cu eficiență bună. As vrea sa stiu daca construiți si motoare inrunner ? Deoarece eu produc edf rc in carbon si mar interesa motoare facute pe masura…. !

    Hi Iulian,

    This is Kushal Kholapurkar from Nagpur India.

    We are working on electric two wheeler project.

    We need BLDC Motor Controller design with prototype for 72V, 3KW & 72V, 5KW system. Also we want to incorporate WIFI DIRECT module in drive to control from Mobile app.

    Also we need Battery charger design with prototype for Li ion battery bank of 72V, 48Ah.

    We Need Battery management System design with prototype for 72V, 48Ah.
    In this battery Bank we have 2 modules of 72V, 24Ah each inter connected.
    We are using SAMSUNG 18650 cells, 20 Series and 8 parallel configuration in each 72V, 24Ah module.

    We request you to kindly give us best possible quote for design transfer, prototypes and Technical support for the above mentioned project

    Awaiting your early reply,

    Thanks & With Best Regards,

    hi I would like information for this type of engines:
    are they single-phase or three-phase?
    how much current do they absorb?
    which counter serves kw?
    how many laps can they get?
    can they be connected to an incoder to follow the siri transmitted by another instrument?
    for the purchase of two engines which is the price?
    thank you
