Motor controller replacement, what if...

could this MC be an alternative?

I do not know if it is possible to get a customized firmware for a NFO Sinus controller.

They also offer a 5 year guarantee of ball bearings since there are no current passing that way because of the sinus-shaped feeding.

Yes, it is a big box, but probably due to large capacitors when fed with AC, so it might be possible to reduce the size.

From the site: http://www.nfo.se/
THE PATENT: NFO Natural Field Orientation
Does not need a sensor on the motor

It is a small company with a unique product, so they might be helpful.

Here are some other discussions on the same subject;

I just don't have any information on the Vectrix motor, I read somewhere it was 3 phase DC, I guess I will put a scope on it to see what I need to drive it. I just don't have enough information yet..
I was looking for an option if the controller dies, not going to spend more than I paid for the bike to fix it. I would like to be able to program as well, change ramp up etc.

A replacement MC would need to be able to take 145vdc at the input, produce sine wave AC, and do field weakenning

The stock controller does a max phase current of 275A (IIRC)

If you want the same performance, that's what you need

The Sevcon's don't go high enough in voltage

that controller you provided a link for would be plenty powerful

cheapest way to get a replacement controller is to repair the one you already have - usually its just a connection issue on the IGBT module, the module itself is fine

Does any one have a used controler board for sell. I am not sure to remove the IGBT will be enough to fix my Scooter.
Thank for help

Could you post a pic with the IGBT module highlighted please? When you say that it's a connection issue, do you mean like, soldered joints coming loose or something? What's the solution for that.... re-soldering?

Thanks

ps what does IGBT actually stand for??

"Insulated-gate bipolar transistor", a newer high-power transistor type with some drawbacks too. You can look it up on wikipedia if your are deeply interested in understanding what makes them different from MOSFETs (metal oxide semiconductor field-effect transistor).

Anybody can tell me how to get a canbus adapter and the software for a 2007 VX1. I call Peak France they are anable to send eather the canbus adapter and Vectrix software. We can just download the encoder software from their website.
Sorry for my bad enlish and many thank for anyhelp

I found a peak interface a year ago in ebay Serge and the firmware came from a member here by email.

regards

Klaus

Thank you Klaus
Matt send me directly all the informations to get a new can bus and an ICBT.
uscomponent.com for the ICBT
gridconnect.com for the can bus
I just order both and I am now waiting to get them. Then I will try to have my Vectrix back on the road.
A member send me as well the firmware.
It is very kind to see how Vectrix owners are helpfull.
Best Regards
Serge

Can you elaborate on this please? What specifically do you mean by connection issue and what is usually the fix for it? Thinking ahead here........
