24 FET 10000Watts Muscular High Current LYEN Controller $299

[Lyen]

Caution: You are entering the midsized motorcycle territory with this controller. The controller is designed for electric motorcycle application only, it has enough current to heat up and melt the motor phase wires of most electric bike hub motors.

These are newly hand assembled Infineon 24 FET controllers I am selling, they are new and never used. It is originally optimized to be used with midsized electric motorcycle and ebike racing applications. The best motor to be used are the the Crystalyte 5 series and motorcycle hub motors.

There are lots of potential and features you can unveil and twist as you go. You can program functions such as enable power regeneration, regenerate braking, pulse width modulation, low voltage cut-off, interface with a Cycle Analyst, and others. You may also add an USB to TTL serial adapter and connect to the controller for tuning. (Electronics knowledge is required to unleash the potential however)

If you are going to use a 9C (Nine Continent) motor, it is recommended to reduce the current setup due to the thinner gauge wires being used with the hub motor. There is a potential that any current & voltage combination higher than the current 72V @ 65A will melt the phase wires in the hub motor and cause potential damage.

One unique design is the welcome of the embedded switching power circuitry to step down the high voltage and feed the MCU (motor control unit). The static-state current switch module that draws only 22mA, which is about 1/3 current draw of the current controllers using the high power resistor. This way, the controller will run much cooler and more energy efficient.

Another unique feature of this controller is that it has an additional speed sensor circuitry built-in with an extra output lead/pin. It is to be used with the scooter style electric bike and electric scooters that have a speedometer in the dashboard that reads electrical pulses.

If you look carefully in the pictures, you will notice this version also uses lock washers to secure the FETs internally and the heat transfer bar outside to place tension against a nut after tightening. It is also to help prevent the nut from loosening. The FETs will get overheated and damaged when detached from the heat-sink which used to be the case from the previous designs.

Lastly, there is no compromise for safety. The controller is equipped with silicon and high temperature wires for flexibility and heat resistance up to 200 degree Celsius or 392 degree Fahrenheit. The phase wires to the motor are also high temperature equipped. I have also added the high power connectors so you do not have to.

This is a top of the line controller that comes with all the bells and whistles that are typical needed for the racing application including the CA connector, regen enable/disable jumper, and the USB-TTL plug for use with the programming adapter.

$15 for USB-TTL programming adapter with a push to send button and connector. Windows XP/Vista/7 32/64 bit operating system (real 32/64bit drivers).

I currently have only 20 made as of June 15th, 2013 since I am busy working on my other ebike projects. My intention for selling at such low price is to share the fun with other ES forum members instead of making them jealous. I finally understand why Methods mentioned the cost of labor is steep after all this and I have to agree with him from now on. These controllers are not generic controllers. I have every single one serialized. Quantity is limited, buy it now and upgrade later once your piggy bank is filled up if needed.

$299 USD free ground shipping in the US & Canada. For other locations, please PM or email me at LYEN@HOTMAIL.COM. I accept PayPal, cash or money order. The controllers will be shipped out from me in San Francisco, California, USA. I will provide a tracking number and ship it out as soon as I have received the fund.

Doesn't make sense,huh?

You don't use kapton tape to isolate the FET's. Why?

I'll build two e-pocketbikes based on the HXT 80-100. Is there a sensorless option in the infineon SW?
-Olaf

[Lyen]

Dear Olaf-Lampe,

Thanks for your acknowledgment on the description discrepancy. I have updated it to make more sense now.

The heatsink compound for the computer CPU and thermal transfer tape are good enough since the original design of the controller does not requires to run hot for better efficiency.

Your HXT 80-100 is indeed a powerful RC motor. The sensorless option can be obtained via additional circuitry such as the one below.

Lyen

Thanks Lyen for the information about sensorless infineon controllers.
The 6 FET version you're selling is the only one with this chip on board? I doubt it can be beefed up to 100A, right?
Is it the sensorless chip that makes the 6 FET controller so slow? ( you mention 2200 RPM for the Astro and Turnigy )
Sorry for hijacking this thread...

Dear Olaf,

I have sent you a PM in regards to the sensorless information since it is not related to the original intend of the post.

...for higher or lower voltage & current such as 36V-100V, you may need to change the resistor network to avoid damage to the switching voltage regulation circuitry)

If you can do this before shipping (change the resistor network for 100v), I'll take one right now.

If you are not satisfy with the results or if it is too much power for you, you may send it back to me within 30 days in an unmodified condition.

Don't worry, I never saw anything such as 'too much power'

[Lyen]

Hi MadRhino,

Thanks again for your interest for more controllers. Yes, I can make the change the resistor network for 100v for you. I have also sent you a reply via your email address on the purchase.

Best Regards,
Lyen

Many thanks Lyen

while I'm waiting for it to arrive, I'll be working to put this new power at good use.

[AmpEater]

I'd like to buy one of these 24 fet controllers from you Lyen, but the only way that works for me right now is if I can roll my unused 12 fet HV racing controller into the price. Could you do that?

Hi AmpEater,

Thanks for your interest in the controller. It would be best to sell your existing controller in the forum and purchase another one. You will very likely get nearly what you have paid for.

Lyen

[STGMT]

Hi Lyen,

I want to use one of those monsters at one Turnigy 80-100 but for a hi power / hi speed / fast acceleration application. What is the max rpm that controler can handle?

I'm looking for 10krpm (hi-speed ), sensored (hi-torque/hi-acceleration), 77,7v and 80A (hi-power?).

Can this monster handle it?

Hello STGMT,

Just to confirm something Lyen, what are the max Phase Amps this controller will do?

[John in CR]

... what are the max Phase Amps this controller will do?

Controller limits are very motor dependent, as well as how a bike is used. Lower inductance motors will pop controllers at much lower settings than those wound for a lower Kv. Voltage and typical throttle usage play a role too. eg I ride my 100+mph ebike mostly in the 35-45mph range, and because that puts it in low duty cycle and phase current multiplication almost all the time, it is much much more stressful for controllers than if I rode the same with the bike at a lower voltage. I just don't want to give up my extreme top speed quite yet.
