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

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?

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?My controller might get here by this weekend. How do I connect it to 5yr old crystalyte motor ?
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.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.
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.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!
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.Can i run these on 44 66 and 88 volt lipo packs? Sometimes 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?
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!Neptronix wrote:By the way..
What is the highest amount of amperage anyone has got away with pushing through these?
40 - 50 amps?
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...Can't wait until mine comes in. Not that I have a motor or a battery yet, but *SO* excited for the first part of my ebike. . [It is also being used for testing purposes on another person's bike].
