About me, Contact
By iulian207My name is Berca Iulian, I`m from The Netherlands. I studied electrical engineering, specialty Electric Motors and Metrology.
I`m developing cutting edge motors and controllers for electric propulsion systems. I have designed and built motors with power range from 1kW to 500kW until now. On the website you can find a tiny fraction of the projects, since I can not post proprietary projects.
I have my own small CNC machine, and I was able to make several motor housings. Is a lot of work behind, much more that it seems.
As a hobby I have built: an electric car , electric scooters, bicycles, go karts, quadcopters ,rc airplanes etc…
I am very passionate about electric motor design, motor controllers, I’m working to develop and improve the brushless controller and I’m building brushless motors for: Light Airplanes, Large drones, Electric Scooters, Electric cars, boats, Pumps and many other applications.
The new motors I`m developing are bringing high performance at a reasonable prices.
The motors are high performance type, due to high frequency capability of materials used, careful optimized core design, optimized winding design compared with what industry is using. By being able to design as I consider optimum, I can go in regions where big companies are behind do to old standards. In this way i will be always move faster than them, with years in advance.
My YouTube channel is on http://www.youtube.com/user/iulian207?feature=mhee
Have a nice day, and remember: nothing is impossible, with enough effort.

Buna ziua,
Ai putea sa imi dai un pret pentru masina electrica Agila pe care ai facut-o?
As fi interest sa o cumpar.
Multumesc,
Ionel DINU
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.

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
THanks

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
I may have put wrong email address over last 6 months etc

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
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.

Hi Iulian
First I must congratulate on your hard work and very succefull motor/ Controller project.
I like in the UK and I’ve been interested on the subject of dynamic balancing.
I like your methode and equipment used for balcing a motor rotor, do you thing this same settup can be used for balancing car turbo chargers ? I guess what im really asking is whether its sensitive enough to balance such a small assembly (approx 300Grams )
Hi, I think it is. You can change the sensitivity of the accelerometers.
Iulian
you don’t have a lower capacity BLDC like 10kW running at 6000-9000rpm with permanent Magnet too.
The company I’m working for could ve very interested in buying one
Hello
I design a custom experimental aircraft. For that, I need to make one or more brushless motor, to obtain 60 Hp, rpm
I want to pay for your services.
how much your advice would cost to help me to manufacture it from scratch ?
The idea, is make myself all of the motor, but I have no time to search howto design and how to do.
I don’t want to buy a ready made engine, I want to manufacture all the parts of the plane, including the engine.
Thank in advance

Can you built a prototype from my own blue print?
Hi Berca,
Have been following your work on the internet for sometime now. I have a Mercedes 190e (2.3, 8v 5 speed manual) It used to be my dads car (has a 2.3 cosworth body kit and 17inch amg mono block wheels and for a while i wanted to Ev it. Would you be able to help supply me a kit for this ? I am open to suggestions on the spec. But it should be a fast daily driver with decent range 🙂 .
I am also on a budget to so give me a few options/permutations/ combinations.
A little about me, I am a rally driver for the last 20 years in India, I also build and manage motor-sport cars for a few teams.
Looking forward to keeping in touch .

Hello I am going to create my own car but we dont have an engine if you want you can participate to our project and be in the compagny just write me an e-mail if your are interrested
Hello Iulian.
It’s great seeing you work on motors that are affordable for common people, i have recently started my own startup in India which is building affordable electric light duty vehicles we looking for a powertain that would power our initial prototype but most of the motor specs we want are either only available for large OEMs and the ones in DIY community were very expensive for what they were offering. Your projects have been a really exciting find so i wanted to know if you are willing to work with us . If so i would be happy to talk to you with regards to this. Hope to hear from you soon
i like to buy this setup for my training institution . please send price .thanks.
Hello Berca Iulian,
Very impressive indeed. I am planning to undertake an EV conversion on certain existing petrol cars; Toyota Corolla and Honda Civic. Need a motor and controller but has to be affordable. How about you provide me with a design / prototype of a BLDC motor plus controller of around 80/90 Kw rated at 4000 rpm. Want to replace the engine and put in a motor instead. We would compensate you suitably.
I would love to hear from you.
Sincerely,
Muhammad Jawad

I am interested in buying 4 of your 35KW DC motors. I am designing and building a Quatro copter that will hoist a 20×20 m QR panel into the air. I want to control it in similar fashion like today the store-bought toy quarto copers are controlled – I would need your help in properly specking this out and the type of battery I will need.
I have no problem considering you becoming a partner for profit-sharing.
I like the fact that you are from the Netherland because I have only respect for your people.
I hope we can start a discussion.

Hello Julian,
My name is Brian McCraw, I have partnered with Tennessee Tech University for a device I believe will have significant impact on the maritime industry. A provisional has been filed and the patent is being worked on in conjunction with the university. We are going to begin working on a prototype. I have many choices in electric motors and generators, I am however impressed with the quality of your work and your passion. That said I would like to buy two of your motors for our prototype. and would love to get your input on all three phases of the plan going forward. let me know if you have interest. I will send you and NDA and the design. regardless I think you have done wonderful work. and I love the little guy. Quality is quality. have a good evening

Hi, Please senr me an e-mail at the address found at about, contact.
Hello Iulian!
I wonder if you sell your AC PMSM motor and controller as a Kit. If you have a catalog with specs and prices it could be really nice to try your developments in a car conversion.
What is your opinion about DC Series Wound Motors (DCSWM) for Electric Car conversions? Many 9″ or 11″ motors were used to convert vehicles world-wide over the past 2+ decades using several brands: General Electric, Advanced DC Motors (a.k.a A.M.D.), Kostov and NetGain. I still use some in a couple of cars. As you know: they offer no Regen and they have brushes to replace every 10 years or so, those motors have great torque, the industry seems to discard or kill their production forever and I wonder why. In terms of efficiency, they are below 90% line, somewhere above 85% vs most AC who are above 90%. But any ICE motor efficiency is around 25% only, so I don’t see a reason to send those DC motors to the books of motor history.
What is the motor efficiency formula that you use by the way?
What is your experience on DCPM brushed motors? I’m using one with regen in a VW.
Have you developed SynR Motor? (Synchronous Reluctance) with or without internal Permanent Magnets.
I’d love to get one of your kits. Thank you,
Hector
Good morning
I write from Italy, my name is Stefano Puscio I am an industrial expert with specialization in industrial mechanics.
I am making an electric motobike. I would need to make a brusless electric motor different from the others. I would like to show you my project for a collaboration.
Thank you
Berca,
You can raise efficiency further by using bifilar windings for the stator coils and harvesting the back emf of the reverse windings diode isolated back into cap bank.
Kind of like a 4 quadrant power supply.
Beautiful work!
Hallo Iulian,
Ik heb uw site gelezen en de video op youtube bekeken. Ik heb een project en ik ben geïnteresseerd in samenwerking met u. Ik heb hulp nodig bij het berekenen van de stator van de motor van de LG-wasmachine om deze te versterken, de windingen te berekenen, ik zal neodymium magneten op de rotor plakken. Ik begrijp dat u de mogelijkheid heeft om werkzaamheden op een draaibank uit te voeren, klopt dat? Ik woon in Rotterdam.

I use a 72v esc controller for a samsung direct drive that I modified.
Do you design ESCs with 230v dc 10amps voltage?
Your engines look really great.
I have a 100rpm workout to find.
How long does it take to order one of your engines?
Are there any smaller ones?
Thank you very much.

Hello Berca Julian,
I found your site and your shop because I´m planning to build a serious displacement motor yacht about maybe 50-60 tons with an Hybrid propulsion system.
I´m still not sure if I will go to serial or parallel hybrid. The serial hybrid need a motor for the whole range of build in energy – in my case from 0 kw to maybe 330 kw. A parallel hybrid only need an e engine for the low power use from 0 kW – max 50 kW.
The point is the high cost of a powerful e-engine with high torque in full use and low noise. I have seen your e motors are running in high speed, but I need only max 800-1000 U/min and arround 1500 – 1600 Nm.
I have seen your Videos and I´m impressed about the efficiency, the light weight and the good looking quality work. I´m not an electrician and have no idea if your engines are usable for my plans. maybe you can give me some infos.
I´m still in the planning phase with my boat, the naval architect is still on beginning with the drawings and time is enough. I will build at a Netherlands shipyard (Maasbracht) and a ship electrical company is there who know what is to do.
