Would this controller work with a Kollmorgen or BMC brushless motors.
Are these motors sensored or sensorless?
I understand they are fairly durable up to 36 volts.

Hi Drflowers,

Thanks for your interest in the controllers. I have sent you a private message with technical details on both Kollmorgen and BMC motors. I do have both Kollmorgen and BMC can type motos. Some people spell and called Kollmorgen as Kollmorgan. I actually have a couple ebikes setup with the motors:

http://img693.imageshack.us/img693/7497/curriebike2.jpg

Both Kollmorgen and BMC motors are sensored motors. Here are the links on how to wire them:

viewtopic.php?f=3&t=4696&p=73245&hilit=kollmorgen+color#p75440

What I can do is to pre-program the controller and adjust the resistor network inside the controller to accompany with your 24v to 36v battery packs. This way, you do not have to. :)

The 9 FET 4310 MOSFET controller works best with the hall effect throttles although it does works okay with the 5K throttle with an optional throttle adapter.

Please let me know if you would like to purchase any add-on or accessories mentioned in the advertisement, I will then calculate the total and send you a PayPal invoice to purchase. Thank you! :)

I have written a step by step user installation and instruction manual. It will be provided upon purchase. :)

Best Regards,
Lyen

I have got Lyens controller to work on my Kollmorgen motor. There is a thread on ES that shows how to hook up a Kollmorgen to an external controller. Fechter is the one to ask he knows about them. I liked this controller so much I bought one for my new setup. It works great on my BMC motor. It flys at 27mph on the flats at 36v lifepo4 and 30 on 12s lipo. This is one fast motor controller combination and I am very pleased as usual with Lyens product and service. :mrgreen: :mrgreen:

I am just trying to select between Kelly and Lyen. Kelly has a rich catalog with all details specified, I would like to read and compare Lyen's controller parameters too. May be somewhere is a catalog with full specifications of his unmodified controllers?

Main concern for me is ERPM capability of the controller.
It seems that a geared cyclone should have on its shaft: 6600RPM at 36V, 8800RPM at 48V
Cyclone sprocket RPM is less by a factor of 9.3.

To achieve specified RPMs a controller should supply ERPM = RPM*number of poles
Geared Cyclone seems to have 12 poles, then for 36V a controller should provide at least: 6600*12=79200ERPM

According to Kelly's http://www.kellycontroller.com/kbs36101 ... p-502.html
they can customize the model to 70000 ERPM
but unfortunately I am completely missing full specifications for Lyen's controllers to compare.
Where is an official site for Lyen's Infineons?

Just finally put my 9 fet 72v on a bike, after letting lay around awhile. No comparison to the 12 fet or larger stuff of course with 40 amps etc.

But for what I am using it for, REALLY nice! I have a couple slower commuter bikes already, but I wanted a faster, yet economical in watts runabout for quick and short errand trips. I'm loving the 9 fet controller for it. Now I get a much quicker trip to the local stores, and only carry 5 ah of 20s lipo to do a quick blast to the flea market or nearby burger joint.

Sure, I don't get into the 40 mph club with this controller, but I definitely am riding above 30 mph. For those that want a good controller for a faster commute, this may be the perfect choice. I'm cruising at about 1200-1400 watts depending on slight hills. It has a nice soft start so it doesn't hammer the dropouts, and actually pulls only 17 amps when cruising flat ground on my bike, running a 2807.

It's a 20 amp controller, (at least mine is set for that) and it does pull the full amps starting up. Once you get going, it pulls about 17 amps continuous on flat ground. I believe it could be set to a higher amps, but for that I'd really recomend the 12 fet controller. With the 12 fet one, you can set the amps much higher later, if you decide you want that.

The low amps of this controller is perfect for certain situations. It's a bit more thrifty on a very small 5 ah battery, and doesn't tempt me to go 40 mph like the big controller would.

I have 2 of these controllers. With my 9c 9x7 I am pulling around 20 amps max most of the time. But, with my BMC motor I am seeing peak amps around 25-28 amps with it. I think Lyen programmed them a bit differently?

Dogman did you ever get your programming cable and software worked out on yours?

Nope. I'm too stupid to get the program to load on my computer. The instructions are there, but without the knowledge base, I can't make sense of em. I'm a drag and drop kinda guy on computers. Anything more than click and approve to run blows my mind.

I don't know what the phase wire combination is for crystalyte motor is but make the hall sensor wires on lyens controllers require you to switch the blue and green wires.....? Which, crystalyte motor do you have?

YEE HAW! 96v rocks! Lyen sent me the color connections. I followed his advice and connected it first, to make everything working. Here's what it looks like: I have 12 7.2v rc nimh packs on my slide=out rear rack. I have another 96 volter that fits in the frame there. The controller is in my basket for now. I can go 5-6 miles with each battery pack on 96v, or, I can go 10=12 miles each battery on 48v, which I did last weekend. So, I can go 5=6 miles on a single nimh sub c cell. One battery is claimed 6.8ah cells. My other battery is claimed 3.8ah cells. Guess what! They all seem to go the exact same distance!?

I do have some other questions...

I am puzzled by the 2 red poer wires. If I only disconnect the thin red wire, will the controller continue to draw power from my battery? Or do I need to disconnect both of them? Which is how I am doing it now.

I cut off my hall and motor wires coming out of my old blown 100v crystalyte controller, so I still use the trailer connector and the xlr connector. I did not have any bullet connectors for the motor wires, so I cut them off and put spades.

I have a couple questions regarding the regen function. I cannot use it with my current nimh batteries.
Does the ebrake connection engage regen? Or is it purely engaged with the opening of the white wire only? Are these 2 functions independent of each other? Also, if my battery is at 98v, will the controller still regen to it? So that the controller would have to regen over 100v for the regen to work?
tHANK YOU SO MUCH, LYEN, for not only making these controllers to share with us; but, for selling them at such low price. You are a blessing to our world. Thanks!

The thin red one is the ignition wire. It's often disconnected via a key switch leaving the main wires connected. It powers the 5v bus that you need for the throttle and hall sensors in the motor. With out it the controller is functionally inaactive. This has the advantage of not needing a precharge resistor to prevent sparks when plugging in the main power lines or a massive switch to handle them. With it disconnected the mains draw ~10mah. It'd take weeks to discharge a battery at that rate.

With the white wires connected regen is engaged with the ebrakes. IIRC regen only works with battery packs less than 72v with these controllers. There is a mod to get around this, but I wouldn't recommend it for novices.

Can i run these on 44 66 and 88 volt lipo packs? Somtimes it would be nice to lower the voltage to parallel packs for longer range. But most the time i would probly be at 66v. Oh, and how high does the amps go on these 9 FET controls? Is there any of these left to buy?

What is the highest amount of amperage anyone has got away with pushing through these?

40 - 50 amps?

I have run 18s lipo through mine with no problem at all with my 9c setup. I use 10s lipo, 36v lifpo4, 36v lifepo4 with 6s booster packs. 12s lipo, 18s lipo. 18s lipo is a little scary for my setup so I dial down the amps with my CA mainly, because mine is a front wheel setup. PM Lyen and ask him he's real good about getting back to you most of the time. Make sure you set the lvc for the lowest voltage you run though. Mine are set for 36v lifepo4. 8)

I have seen 39 amps peak (watt meter) on my BMC setup at 12s lipo. On my 9c DD I keep it locked at 20 amps (no matter what voltage) 18s is way too much for my taste at 18s lipo it flies!

No wonder y'all gush about Lyen and his work. When you need the best, he's the man for the job! 'grabbed one of these 9FETs last week and installed tonight. Will somebody please explain why you would ever need 12 or more FETs?

Seriously, I had to double check I didn't mix-up packs and load 15S - nope, 12S just feels like 15S with this little monster. Perfect in every detail - Lyen was so patient and helpful with my order.

I asked Lyen for as much power as possible with stock motor wiring. 12S this one peaks around 35A and settles into 17A cruising 22-25MPH flat, no wind, feeding 2807 in 26" wheel. The additional 600-700W startup and climbing power is exactly what I wanted from a small package controller that tucks under the seat.

Another satisfied customer!!!

Runs great on 12s lipo and a BMC motor 32+mph on the flats with mine. With a 9c DD 207 you'll see around 22mph on the flats. It's a nice controller. My only recommendation to anyone is to have it configured with the right lvc and all the bells and whistles before Lyen sends it out to ya. If I get another bldc motor I'll be getting me another one of these. Unless you want or need a high power setup this one is the right one for a fast commuter setup... 8) 8) 8) 8)

There's definitely a HUGE improvement in performance between 9 FET Lyen edition and 9 FET eBikeKit 22A controller. Simply no contest - knowing what I know now, I will never even bother with anything except Lyen controllers for my bikes.

The smallest details are so well executed - 'looks like proper length stainless steel end plate and heat sink hardware using lock washers for the later. Quality of wire and connectors obviously top drawer! Small but important details.

Hook this device up and get ready to experience BLDC power delivery taken to an entirely different level. He obviously rides too so it's very intuitive how power's applied over range of eBike operation. Brilliant, simply brilliant and worth every hard earned Dollar!

I tested with 15S Lipo yesterday and all I can say is - 2.3kW and the outer cover of my hub reached 130F in 5 miles... I'm defintiely sticking with 12S since it feels more like what my old controller felt like running 15S and I simply don't need any more power than 1600-1700W.
