Well I think, now it looks better …

The Controller was picked up now

Not really sure about the minimal solution for the seat back ...

Some better pics …
Controller is at German custom since over a week

Got now the new controller SD300 from Scott Drive.
The battery voltage will rise up now from 120VDC to 800VDC.
He can deliver up to 600Arms for short bursts or let´s say as long I can cool down the controller to 25°C.

Wow, that's a crazy beast!

Do a really careful job with dielectric material choices and insulation thickness and humidity/dew/rain protection if you are going to 800Vdc. I enjoy seeing your projects and you alive buddy!

Hi Luke,
yes I know that it will be very dangerous to work with such high voltages.
But also very funny, it´s declared as LV controller (<1000V).
This project will take while before I can start testing and also for your information, I will start with less voltage first.
The controler already woks with 50V DC as minimum.
At first my challange will be to mount everything inside the actually frame and this frame is to small!
So in parallel I will thinking of stretching it or build a new frame with an own design.
But that´s future stuff. Now I have to safe money first and getting the motor by next year.
Actually he is postboned due to car industry colaboration and long time testing periode.
Btw. theoretically it´s possible to get up to 400kW out of this controller (Scott Drive statement).
The good news are that the motor manufacturer also owned now a SD300 and can really test it and I will get later on all parameter settings.

Best regards from Germany
Andre

You are so all in into this project I can only say respect.

That controller is a true beast. Watch out for using mc boots with steel toes on a rainy day with that thing.

So here you can see how big he is.
Now I have 30 to 31cm space between main frame and controller.
So I am limited in outside diameter for my next motor choice.
It´s only preliminary mounted inside for the energy exhibition I will take part again, as the last two years.
The good thing to lower the seat and rear frame position now is that I can fully open the fuel tank cover now

I love to follow your build. But I can't understand some design choices. Why can't the controller be mounted flat on top of the frame members under the tank cover? Is it too long? And why not mount the motor in/on the rear swing arm so you keep all the space between and under the frame for batteries? With the motor in/on the swing arm you'll have free extra mechanical (weight) downforce and grip at the rear. But this whole build seems more about the looks than technical and financial smart choices to actually compete.

Nice to get get your critical feedback!
I had placed already the controller at fuel tank cover position and yes, the controller ist to long including his cabeling and additionally the liquid colling will be above the inlet fill in of radiator. Means I hat to move also the radiator from his original position to an upper position behind the cockpit. Also the width of the controller is too big at the point where I am sitting! I alos do not want to have the 800V cabeling direct in front of my best friend

.
Regarding the motor position: If i use a 30cm in diameter big motor and want to implement it into the swing arm (how does it looks above

), do you now where the rear wheel is standing? Right, up to 40/45cm over Series as minimum!
Even if I create a new swingarm. You forgett the suspension, which will need also some space for mounting!
I made already this experience with the 40kg hubmotor! Where the wheel base was 35cm (14") above series (spinning wheel of all the tracks I was driving).
And maybe you are right, it´s my design, my money, my experience I will make. I don´t want to follow the whole mass: Even if the project will fails I had fun during this building periode.
I will not start at 800VDC, it wil be a long time project. The controller is also working at 50VDC! But I have enough space to continue, if everything goes right!
My planned motor will be tested next week from motor manufactuer with same controller and therefore I also will get the settings. But the motor is postboned to next year and therefore I have time to save money and if I don´t have the money regarding other private issues it will takes a little bit longer to realize this!
Btw., the controller is not cheap, thats true but I own the EmDrive500 (100kVA) which cost half of the money as SD300. And also if SD300 will not reach the full spec of RMS PM250DZ (both are working up to 800V and deliver 600Arms (RMS:460KVA, SD300:400KVA) I saved 10k€ for near to the same power! So about the financial issue I think it´s actually the best I can do.

I wish you good luck and success.

Rovii · Post by **Rovii** » Apr 03 2019 7:41am

Thanks a lot!
We will see where the journey ends

Actually I am absolut happy and I can present something new on energy exhibition.
I am really sure that there existing not so much SD300 models!
Even Semikron will visit me!
SD300 is using their IGBT modules!

Now I am ready for the energy exhibition.
It´s cleaned now.

Next week I will dismount rear tail and swing arm for coloring.

SlowCo · Post by **SlowCo** » Apr 05 2019 7:10am

Now the size of the controller is really visible with these photo's...

Good luck and enjoy the energy exhibition!

The bike looks like a toy RC bike with that big controller in the frame

Rovii · Post by **Rovii** » Apr 06 2019 10:42pm

Thx guys,
yes, it’s not the smallest one

Now the first day of energy exhibition is over.
Had again as last year a lot of good conversations.
Conversations about the bike and motorcycle.
So I explained in some short sentences about my hobby and how to continue.
Some people like my stuff, some not. But that’s absolutely ok for me!
I am standing in an outside area with perfect weather conditions ( sunshine, 20 degree).
Today I will continue with same weather conditions and some more visitors as last day because of the shops are open Sunday, which is not normal in Germany and in parallel there will be a little spring street festival with a lot of booths.

Got now a second hand, but really looking new GSXR 1000 K2 frame for experimenting and preparation ...

Rovii · Post by **Rovii** » May 11 2019 2:40am

Cutting now not needed material and took some dimensions ...
