Infineon controller identification

[piwhy]

Hello,

I bought few month ago a basic 48V/1kW controller to a Chinese Ebay seller which works fine whith my "GM type motor".
But, I'm wondering to upgrade it for a Lyen Infineon type controller to use the speed avance timing, CA functions and possibly the speed modes.
First of all, I've opened it and I've realised that is an Infineon based controller working on the classic XC846 chip. Now I'm thinking to add this functions on my controller but I need some guidelines...
I found this topic http://endless-sphere.com/forums/viewtopic.php?f=16&t=7361 that refers to this kind of controller, but mine is a bit different.
It use 15-FET 75NF75 and the PCB is a bit different too. I identified most of the components but some pins aren't available (X1, X2, DX3...) --> Pics enclosed.

Does someone has ever used and customized this controller ? What can I expect from this controller ?

Thanks.
PY

I'd have to open it up to be sure, but it looks just about exactly like the Methods 18FET I have, from memory (which I don't think is programmable with the existing "Keywin" software). Not sure about the rest of your questions till I verify that (whcih could take a while, as I'm spending most of my time working on a new bike right now).

Ok, so in your opinion I can't modify the configuration. That meen that there is no upgrade possibilities, like the maximum current ?
If I'd like to increase my GM motor power i need to buy a powerful controller ?
Thank you

THat depends. You might be able to physically modify the controller, by replacing the FETs with lower-RDSon types that can handle more current, beefing up high-current traces, replacing caps with lower-ESR types and possibly adding more of them, modifying the shunt to allow more current thru before it limits, etc.

But how well all of that works depends on how the rest of the controller is designed.

how do I recognise if an Infineon controller is sensorless or not?

I found this on ebay : http://cgi.ebay.co.uk/Infineon-Rege...&otn=4&po=LVI&ps=63&clkid=8411964427582987888

it writes that it is for sensored motors,so logically it won't work with sensorless motors,but is there any other sign to check if it is sensored or not except from the notification of the auction?

 

[amberwolf]

Unless they advertise it as working with sensorless, I'd just about guarantee that it doesn't. With ebike controllers, it takes special added circuitry to do that, costing more/etc. SO they won't have it in there unless they need it.

Py,

Please reference this thread for info on the speed control pads, P20 and P21. http://www.endless-sphere.com/forums/viewtopic.php?f=4&t=18159&start=15 Of course, you will need to program the board to change the values, as they are probably all 100% by default. Good luck!

Thank you for this thread link !
First I will try to connect to the controller to program it...
In your opinion this controller is compatible with the regen mode ?
If i'd like to increase the maximum current, should I re-program it and re-trace the shunt, or the program modification is enough ?

Thanks,
PY

Just connect BK to Gnd and you should get regen.

I would just reprogram it myself to increase battery and phase currents. I wouldn't go above 30A Battery and 75A phase (2.5x Battery Current) unless you beef up the power traces and upgrade the power wires.

Good Luck!
