200A, 14S lipos ESC to come!!!
 

Here is a picture of my controller. It should be ready soon as I was told the factory was waiting for one electronic component. The engineer have told me that production was stopped due to the lack of MOSFETs, but now I'm here LOL. The engineer will also do some tests before they ship it out to see if everything is within specs and I was told they will try the ESC with various different motors and voltage to make sure everything works fine.

Dang

Looks big though, how big is it?

I want to hear on this! Could be the ultimate controller!


How much?

Looks like a solid ESC. Do you know if it will be able to be programmable my computer?

Hows the price looking on that thing?

It should be just about the same size as a Schulze 40.160 and no price yet. I will have to set a price after I receive all the 20 controllers. The good thing is that this controller will mainly focus on the larger scale vehicles such as the 1/8, 1/7, 1/6, 1/5 and 1/4 scale car/buggy/truck. I got tired of manufactures out there only making big controllers for the aircraft side of the hobby.

I hope it is a solid ESC. The engineer told me that programming will be with a program card, but I have to wait and see with the first unit. What I told the engineer is that I wanted to keep things simple and make sure everything works good specially the brakes. Programming with a PC is good, but not really user friendly when you have to change setting on the go. It basically means you have to get a Laptop and take it to the races or your favorite bashing spot.

Price will be determined after all the controllers get to me. I will have to add everything such as the shipping, MOSFETs (I sent the MOSFETs to the factory) and the price of the controller and service from the factory. This controller will not be for everybody. People have to be careful when it comes to high voltage and high amperage electronics like this. I've been messing with high voltage ESC since the early Aveox systems and I own a few of the newer controllers. So I do have little experience with high voltage ESC.

Looking good so far. Hope to get my hands on one after you finish all the testing and start selling them. Thanks for keeping everyone informed on the progress.

I will keep everyone post on new information regarding this ESC. I have mentioned in another thread that a couple of things could go wrong. The engineer told me that components could fail in manufacturing and the other is the factory never delivers. I'm keeping my fingers crossed for everything to go smooth. I'm also waiting for them to give me an answer on a few 100A+ ESC that will handle 7S, 10S and 14S lipos. I might also ask for a 80 and a 100 volts ESC just for us vehicle guys.

Any thoughts of mass production? :yes:

First thing that came into my mind, but I was only able to find 800pcs. of the MOSFET and the lead time is over 380 days. I'm supposed to receive other part numbers for alternative MOSFETs and if I they are available I'll buy them and make more ESC.

80 and 100v?!! :oh: You plan on a REAL HV setup aren't you? :yes: 100V and 200A would be good for a scooter, never mind a car! That would be good for large 1/5+ scale vehicles though, but the price tag on those lipos is gonna hurt!

It would be great for enduro races against stinkers, I bet the ESC would stay cool for the whole 45min race without needing any extra active cooling!

Someone has to compete with CC and that SHV controller, but like I said they are missing out on us vehicle users LOL. I will wait for a definite answer from the factory. They already said it is easier to make 80 and 100 volts ESC. I will be able to use my 2 36V packs in series for with the 80V ESC, but I will definitely get a 1/5 scale car to try the 100V unit if they make the controllers. One thing I will say right now, I will only have vehicle ESC made.

Great Job lutach.. I hope they work well...

Wow, this is Great! Is that FET board double sided? I am assuming it is... I would love to have a 46volt (14s A123) truck!

Kinda looks like my modified Quark 125b! :mdr:

I hope so too. I love your website btw. I go there often to see if you have other vehicles.

Yes the FET board is double sided. Just to let you all know, the 100A controller that I have has great start up just like the Quark and MGM.

Will the controller board be separate from the power board like it is in the picture? It would be nice if that were the case so there could be some extra heatsink-ing going on (unlike other ESCs that have the controller board next to the FETs).

Yes, the controller board is separate from the power board. I don't think this controller will need a heatsink, but it is nice to know there will be some spacing for one.

Well... that depends on what you are using it in... :diablo:

The 100A 10S controller did put out 3780+ watts and it didn't get hurt at all. I will do some runs with tall gearing to see if it will overheat. If it does, I will add heatsinks to the ESC.

Geez, now we are talking! :mdr:

Finally a controller that will handle whatever you throw at it! BTW, what FET's are these? Do you have a spec sheet?

The FET's are the NXP (Philips) PHB160NQ08T http://www.nxp.com/acrobat_download/...60NQ08T-01.pdf

are you gonna water proof that esc with some conforming compound?... would be nice with a heatsink on it.. but I love the big FETs..

I'm waiting for one of my clients to send me information on what is the best conforming compound out in the market today. A heatsink will be nice, but I have read some where that the big FETs will cool better when air is blown directly on them. I was thinking about adding some small fans on both sides of the controller and maybe incase everything in Polycarbonate.

This controller is looking mighty impressive so far...I can't wait to hear how it performs! Encasing it in transparent polycarb would look fantastic IMO...I personally love being able to see the innards of electronics.:yes: Good luck on the production run going smoothly.:smile:

Kind of like me, I like to see what makes things tick LOL. I will keep everyone informed on performance and I hope it will be good.

to have best of both worlds.. make a heatsink that is also capable of wather cooling... that would be the icing on the cake man...

That is what I'm going to do for the ones I'm keeping, as I plan on making a custom chassis that will have space to house a water cooling system.

for conforming compound.. you could use high quality 100% silicone, and mix with lighter fluid untill it feels like pancake batter, but no thinner than this or it will never dry... you'll figure something out.. :D

I was going to make something like the M.Troniks, but I want to get to the components in case they fail, so I ruled that out. What I might do is use a conformal coating that comes in spray bottles, make a nice case out of Polycarbonate and add small fans on each side. After I receive the first controller, I'll take some dimensions and make a custom low profile liquid cooled heatsink. One thing I will do for the radiator will be to add TEC devices and low profile fans to cool the liquid down. I know a few places that makes small 5vdc water pumps. In the future, I want to make my own R/C trucks and buggies and I will also try to offer a ARTR or a RTR versions of them. I have all the drawings for the chassis and motor mounts. I found a place that will machine everything for $45HR, but I will see if Mike can help me out on this.

hey put a pic of that esc on rumrunnerracing.com(fe boat forum) guys are always looking for big power like that

It's there.

I like this ESC as well despite the large size. However, the only thing that would make me hesitate to purchase something like this would be the relatively small supply and possible difficulty in obtaining parts for service down the road. Of course, if it was around the same price as the MM, then it wouldn't be an issue. ;)

No matter what, I like where you're going with this (except the fan) and am curious how well this progresses.

The engineer will send me a 100A controller that handles 7S lipos. He said he didn't have the FETs for a 10S controller. I also posted thin information in rumrunnerracing.com and one member there mentioned he has a true 150A continuous controller and he said mine will only do 95A. Here is the link: http://www.rumrunnerracing.com/fefor...ad.php?t=23246 please look at the 17th and 18th post. I might not be as smart as that guy, but I know the copper traces and FETs will never be able to put out 150A of continuous current. It would also take a really complex cooling system to keep a FET cool at 150A continuous duty. Like I said in that thread, I don't want to sound rude, but I'm doing something for us car guys and I can't have someone ruin this right now.

There is always an expert somewhere that swears to know more by just looking at picture.

Interesting discussion down there...
Serious gaps in calculating and estimating FET's performance and do not worry about PCB traces, for serious currents adding copper bars solves the problem.

Most FET packages (TO220/262...) not rated to deliver what die itself can.

Is there a reason why FETs don't have an electrically insulated metal "insert" to help cool them? Adding a heatsink to the epoxy package definitely helps, but it IS plastic after all.

Do you think that guy is for real with his true 150A continuous controller? What he basically said is that my controller is a 95A controller. I'll just have to wait and put out the numbers.
