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

Post by Lyen » Mar 16 2010 6:16pm

These are newly hand assembled Infineon 9 FET controllers I am selling, they are new and never used. It is originally designed for long distance commute in the San Francisco area. It is also best to be used on electric bikes with smaller wheels such as those 16" to 20" wheels found on most folding bikes & scooter style ebikes for more speed. For those who owns battery packs with 10-15Ah in capacity this is the controller for you to avoid getting the battery management system circuitry (BMS) tripped or experience power protection shutdown enabling due to insufficient current flow (low discharge rate) available from the battery and low amperage designs in most 10-15Ah capacity battery packs.

The controller is like a wolf in sheep's skin because it is under tuned in order to optimize for long range. 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 RS232 serial adapter and connect to the computer for tuning. (Electronics knowledge is required to unleash the potential however)

One unique feature of this controller is that it has an additional speed sensor circuitry built-in with an extra blue wire for output. It is to be used with the scooter style electric bike and electric scooters that have a speedometer in the dashboard. As of April 5th, 2010 the speed sensor wire has been embedded and integrated with the green wire on the CA connector since they both can share the same function now. More practical and less confusion as suggested by previous buyers. :)

If you look carefully in the photos, 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.

* For the extremists, you may double and possibly triple the current output to make it a mighty wonder by adding braids wires (http://www.radioshack.com/product/index ... Id=2062744),add solders to beef up the circuit board traces and shunt. It may also be needed to upgrade to larger capacitors, gauge wires for both the battery and the phase wires to the motor. However, if you are going to use a 9C (Nine Continent) motor, It is recommended to maximize the current output at 65A 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. A good observation and one that I think plays a big part in showing why the small 9 FET controllers can seem to pack such a punch when modded. The gate drive circuit in the Infineons I have looks to be pretty similar, certainly the 18 FET circuit doesn't look like it can provide much more gate drive than the 9 FET circuit. My guess is that this is one of the reasons why a well-modified 9 FET controller will seemingly run at upwards of 60 to 70 amps without getting hot; the 9 FET drives the FET gates harder and therefore more efficiently. On my list of things to do one day is acquire some really big FETs and see just what a 9 FET controller can do. I think that, fitted with external FET wiring and shunt, it would easily be capable of running at 65A or more, reliably.

Below is the specification:
Model: EC-094310-LYEN EDITION
Start immediate controller
Chipset: XCKJ8B116A (same chipset being used as in the 18 FET controller)
Circuit board version: EB209-A-3
9 x genuine IRFB 4310 MOSFET N-CH 100V (tested up to 110V before damage) for more information about the FET, click the link below:
http://parts.digikey.com/1/parts/102113 ... b4310.html)
Large 100V 470uF Chengx capacitors equipped (http://dgfoley.en.alibaba.com/product/2 ... 3_LP_.html)
72V battery optimized (for higher or lower voltage & current such as 24V-100V, you may need to change the resistor network to avoid damage to the LM317 linear voltage regulator)
30A is the current rate (for higher current, you may need to beef up the trace, shunt, and reprogram it via the software)
Low voltage cut-off: 62.5v
Battery and motor phase wires gauge size: 12AWG (High voltage capable wires equipped)
Dimension: 4.84" x 3.4" x 1.75" (123mm x 87mm x 45mm) plus mount extensions
Total weight: 445 gram

In case you want to upgrade it later on to became Methods-proof and Doctorbass-proof, you may need to upgrade the FETs to 4110 to achieve higher current as well as voltage above 100V. We have a friend here Steveo who do awesome controllers upgrade for a fee. :)

I have only 50 made 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. :wink: 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. :lol:

$89 USD free ground shipping in the United States & 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.

For only $10 more, I can include the the following:
1. CA connector
2. Regenerative enable/disable (Enabled simply by connect the wires together without the need to open the case)
3. USB-TTL 5 pin connector (for use with the USB-TTL adapter that is sold separate)

I also have the USB-TTL adapter for adjust and alter the controller settings on your computer. It has the extra 5 pin plug and a "SEND" button. It is also compatible with Windows XP/Vista/7 32/64 bit operating system (real 32/64bit drivers). $15 with purchase, $20 if purchase separately.

You may click on the PayPal Buy It Now link below. For accessories, please send money via PayPal or send me a private message for the total price. Thanks!
https://www.paypal.com/cgi-bin/webscr?c ... MY46WP98CG


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

Update: Jan 28th, 2015 > I can adjust the controller for 24V, 33V, 36V, 48V, 60V, 66V, 72V, 84V, and other battery settings upon request.

Lyen,

I've installed the software components, but need a little help to build the TTL/USB cable out for my EC 094110-Lyen #1009L004. I have a cable TTL/USB (that has a DB9 serial input), but I'm not sure what lands to solder on the board to a connector hooked up. Do you have a link or can you forward me instructions?

Thanks,
Kevo

Hello Cord!

Thanks for you interest in this awesome controller. Yes, this controller can runs at 100V with your 24s LiPo battery packs. However, please be very careful when working at high voltage. High voltage application like this can shock you to death. So wear protective glove is advise during installation and testing. :)

I'd be very surprised if a 9c can handle that much current. I'd be surprised if you could even rewire it with thick enough phase leads due to the fairly narrow axle bore the leads must be threaded through. But if you succeed, be sure to post of your exploits.

Hi Chroot!

Yes, you are correct that with the more number of MOSFET (18 FET), the more powerful it is than the 9 FET controller. Your electric bike will never be the same. :wink:

Please let me know if you have any other questions. :)

Dear Auraslip,

Technically, it is a good practice to bypass a resistor to maintain the voltage to the regulator. But in reality, the controller does works without making any changes. :)

I have just sent you a PM for more info. :)

Hi Ecodean!

Thanks for your interest in the controller. You can simply bypass or short a resistor on the circuit board and program it via the software. I can pre-program it and bypass a resistor for you before I ship it out. :)

Please let me know if you have any other questions.

Hello Lyen
I was wondering if the 9FET will do 36/72 volt on the fly?
I will be running 4 dewalt 36 volts now,but when I find more money I'm thinking of going to 72
volt.
I'll be using a 6x10 from ebikekits.
What conserns me is LVC at 36volts isn't the same at 72volts.
Don't want to blow up my new to me A123's :wink:
I would like to just flip a switch to go from 36volts to 72volts while I ride 8)
I know this 6X10 is not a monster motor so I'm not expecting a lot from it ,but but otoh
there's always the delta Y switch :)

Dear Johnnythefox,

Thanks for your interest in the controller! Yes, it can be done. In fact, it has already been done. :)
The additional cost to add the flip switch and modify the circuitry for dual 36v/72vLVC settings is only $10. This way, you can accompany both your 36v and 72v without the risk of damage. :)

Please let me if you have any other questions. Thank you!

I don't understand how a 9 FET controller would work. Since you need 1 fet per phase, for both the push and pull, you need 6 per set of fets. How are the 9 fets distributed among the 3 phases? I am very curious.
