9 FET 72V Infineon Brushless Controller (LYEN's Edition) $89

[wineboyrider]

You have to use this one with the BMC as it is not a Direct Drive motor. AFAIK the speed only calculates properly with a DD motor. I know I have the CA-DP and wish I would have bought the CA-DPS as I like to use it with my 9c and my BMC setup. The CA-DP works, but the speed shows you as going much faster than you really are.... [/quote]

The gears in a geard motor have a typical ratio of 5:1. So it should show you your speed x 5
Have you tried to feed in 1/5 of the true wheel diameter when programming the CA?
That should do the trick or not?
I cannot try it because I haven't got it yet.

And I am really curious if this might work!

Clever! I will try it and post back! Right now I am using the mini motor?????????which is also geared!!! If this works it would be great, but isn't the freewheeling aspect a factor as well?

[Quajochem]

Good point! But what's the point of measuring your speed when freewheeling anyway?

My #1 bike with the 9FET Lyen edition has been sitting about a month for wheel repair. (long story for another time...) So, 'been riding old #2 bike with what looks like a 12FET Conhismotor long housing controller.

#1 is back on the road and now being able to compare back to back, I gotta give mad props to this little 9FET Lyen edition. The thing is so smooth, it pulls strong when it should but doesn't draw excessive Amps and the throttle response is very linear throughout the entire range. The differences are night/day - stock Conhis controller doesn't even come close when used with basically the same motors/throttle.

I never thought there would be so much difference but it's there and whatever Lyen's doing to provide a better controller it's working!

Lyen;

My setup..... Ebikekit gear hub on a 24" rear wheel. I will be running this at 48v, maybe later go up to 60v. I will be riding on flat ground. Will this controller work with my setup? Do you have any units left? Is there any other info that you need? Also want the CA anyalst setup too.

Just picked up a used 9fet and despite my efforts I'm not finding anywhere the default values programmed into this controller. My used one came with a programming cable so I'd like to experiment with it this summer maybe pushing up to 35-40A sustained with good, cold Montana airflow , but apparently you can't read in existing controller values just blindly send new values. Previous owner states they're all still default as shipped from Lyen so 30A to the motor I assume. Anyone help out? Thanks!

[methods]

The community could probably help more if Lyen made his documentation public and did not make it available only to those who purchase controllers

You would also get a lot more support from the community on the software if it were available for all to see instead of distributed only to those who purchase controllers.




Disclaimer: I sell things similar to what Lyen sells so I could be seen as a "competitor". That aside - I am a member first and a guy who sells stuff second... and if you dont know me well... I am a guy who always speaks his mind (what I believe to be the truth) no matter whether it is appropriate or not. The fact is that I (and many others) worked together for a long time on this board to pioneer our understanding of how these "infineon" controllers operate and we have always shared our knowledge freely so as to help the general public.

I am aware that this is Lyens sale thread.

This is also a thread in a public forum where posters are asking for the help - from Lyen yes - but also from subject matter experts such as myself and many, many others. It only follows that we (those who help) should have as much at our disposal as possible.

I speak only for myself and not on behalf of anyone else or any group of people.

To answer your question... no you cant read values out and your best bet is to just re-flash the controller with known good values. Who knows what bits the last guy diddled.

I assume that you got a version of the software from the guy you got the controller from- along with the manual and programming cable.

Yeah, got software/cable etc. Just looking for baseline values to start with. Didn't realize this was "closed" software. That's too bad. We'll see what the CA readings give me once I'm riding.

[Ypedal]

i have to agree here, i got few of these controllers on my hands and have not dared to hook any of them to my laptop for fear of turning them into a brick.. but i would like to and will soo need to do this as my trike will be using regen, the chopper needs tweaks and i have a general curiosity of how this works......

There must be a few threads floating around ES ??? no ?

Is there a feature to perform a backup of existing parameters if you want to create a restore point? even if you canot read what values are set ?

[methods]

A few threads?
Try a few hundred.

We have beaten the infineon controller to death and discussed it ad nauseum. The problem is that every few weeks Infineon (who XIE Chang or whoever it is this week) releases a slightly different version of the chip or the software interface or the circuit board... so there is no way to make a wiki or anything that will be of any value over time. It really just boils down to staying on top of it and sharing what we find.

There are about 10 guys on the board who are always rolling up their sleeves and translating their way into the latest releases to get things working - but those threads are buried pretty deep in the technical section.

[nicobie]

When you install Lyen's software then chose your controller (12 fet,18 fet etc.) a screen pops up that shows the values that can be changed by the user. I always assumed that the numbers shown were Lyen's default values.

But I could be wrong...

Hey guys, I have been building my second bike for about 8 months,(been taking care of my mom, Long road),anyway, I have last years Ampedbikes rear dd motor and Edward Lyen's 72v 9 fet controller, Edward has been very helpful to me with possible controller and phase combo's, but I am leary of trying them, I am not sure if the setup is MXUS or 9C or other motor. Does anyone have any experience with this setup? I am trying to avoid any unnecessary steps if possible! To avoid ruining anything. Also, I need to know how many poles this particular motor has so I can calibrate my DP Cycle Analyst,also from Lyen. Thank's I want to get this wired up this weekend and this will be my main tranportation when I retire my test mule! I tried to start a new post for this , pardon my noobie'ness. Randel

There are only a total of 36 combinations of hall and phase wires, actually 3 times less genuine ones if you take it relatively. Try different combos with a light brief throttle pull to see if the wheel turns without ill effects. If it turns in reverse direction, swap 2 phases and equal colored hall wires to reverse it back to normal direction. Don't be afraid to try, just don't do it with full throttle or extended time, before you find the correct combo.

[999zip999]

Thanks works great on a 2810 plus A123 20 ah 24s. 30amp only ? perfect. 2260 watts and strong
Maybe 40 amps, Lyen is it limited ? Lots of hills maybe to warm at 40amps ? No small S.F. stuff and don't want to walk my bike up ricearoni hill..

[Frank16]

I can't figure out if it is possible to connect BOTH a (digital) PAS sensor AND (a throttle OR a 6 position LED controller panel)

My current 250W standard controller allows me to turn everything on, step on the bike and paddle away. The PAS then turns on the power to the motor and a 6 position control panel sets the cruise speed. The Infineon type of controller seems to work differently and I can't figure it out.

Any help welcome.
Thanks,
Frank

i think i read you saying somewhere not to try programming a controller if you don't know what you're doing. is this true? if so, what knowledge is necessary to program one of your controllers? i'm new to ES but have read a lot of people that are using your controllers. another plus is that you use infineon and they are the best for waterproofing. i live in seattle and that is very important to me because i have to ride rain or shine.

[Allex]

Does anybody know how to connect the ignition switch to this controller?

[Ykick]

Loose red wire looks like the one to connect to switched power from battery +

When I bought this controller a few weeks ago you said on your original post

I have only 30 made since I am busy working on my other ebike projects.

Now it says

I have only 33 made since I am busy working on my other ebike projects.

Are you willingly deceiving us to sell faster?

Quantity is limited, buy it now and upgrade later once your piggy bank is filled up if needed.

Lol. So he had time to finish 3 more even while he is busy working on his other ebike projects. That wouldn't be scamming... And by the way I think the limited edition scam works better the other way where you lower the amount of items in stock so people think they have to really hurry to get one.

I would say you got it all mixed up there. And you got your product at a price you were willing to pay so what's the problem anyways?

You seem very defensive, did I offend you in any way?

Having gotten around to make small number of extra units is a valid excuse.
And I never used the word 'scam' because that would be absolutely the wrong word for it, just misleading marketing.

[Boeckstyns]

No no. Not defensive in any way. I just couldn't understand the problem. And had a bit of spare time to write a meaningless post.
No harm intended. Cheers

[lollandster]

Cheers
On the positive side I may inform that I tried the controller on both 36v 12s LiFePO4 and 74v 20s LiPo and you can jump between them without changing anything and that is neat. I'm also glad of course that the 9Fet is still for sale because it is a good controller that kept cold while pushing 3kw into the SmartPie until I had to stop in fear of burning the motor (reached 110'C inside the motor).

The shunt value seams to be off though.

[k-harvey]

could one work on 24v cyclone 500w+ as the internal ones often fail, 3 out of about 9 that i suplied .Also then theres the throdle to make fit
