CC Doing SHV
 

SHV = Super High Voltage

CC has been working on a SHV airplane controller. 90v (20s Lipo) and 200amps, with bursts up to 400amps. That's ~24hp or 48hp in bursts!

WOW! Too bad someone couldn't hack the firmware for car use (add brake/reverse)!

Criminy, that could power a mini-bike or something for personal transportation use!

WOW!

that was moving some air!!!!!!!!!!!!!!!!!!!

well wheres the land one now? lol

I put one of those things in a pit bike!! :027: I bet it can move my small body around pretty good, eh? lol

Damn... thats a lot of power.

haha, nice...that would power a little pit bike...

Yeah, that's nice, but I'd settle for a low voltage controller, say 5S lipo that'll run in a car. Maybe in the form of a Mamba Monster Max. LOL.

Hmmm!!!
20s lipo in my gtx. That is an idea.

I wouldn't hold my breath till they launch it Leroy..

If thing keep going like they are, the next generation will get to run the MMM and the MMMhv

it's a start
 

You may also want to consider our new 8S Mamba Monster and motor for the 1/5th scale HPI Baja B/T conversion we will be releasing soon. That vehicle weighs over twenty pounds, and our conversion really powers it right into the range you are looking for. It is not available yet, but should be available soon.

Its a start

Quoting Greg from Castle

This project got put on hold in late 2007, and just recently got reopened. Our first product will likely be a 160A, 16S controller.

Don't know if we are going to do a 20S controller in the near future.... safety issues are the main concern.

Thanx!

Patrick

its perfectly safe to affix you best friend to a 20s powered power wheels jeep...

Were still waiting on the big BL motor for our jeep!!!

lol, 16s is "safe", but 20s isn't? :wink:

There's gotta be some kind of disclaimer/waiver you can have people sign before purchasing a SHV ESC that will free you from liability.

I liked that 90v 200A ESC you had on the special projects site a while back. Looked like a small car amp. Would've been nice for a scooter with decent range.

160A, 16S :surprised: :surprised: Any idea on release date of this ESC?

This one?

Impressive power, look forward to reading/learning more about this.

Awesome stuff like always Pat & crew of Castle !!!!

No word on the release date yet - - we are still in the testing phase right now.

8600Watt outrunner: Click

The PERFECT motor for the new 160A 16S ESC in a E-Bike hehe! Well, 300A 16S would be a little safer actually... :lol:

Last year, I was asking for 30S 500 A controllers for our FSAE car http://www.rc-monster.com/forum/show...t=17955&page=2 Castle didn't have any, so we had to go with Kelly.

The max motor current is 500 A per motor and there's one motor for each rear wheel http://www.youtube.com/watch?v=deck4wA1gRQ

If Castle is making an 80S 150 A controller, we'll consider it for our next car.

If you tires aren't squeeling, you ain't driving hard enough. :)

Nice video and car though!

Drove a lot of the MRT5 (McGill's FSAE car from a few years ago; gas powered) via sim (www.liveforspeed.net). Quite a fun little car to drive.

Any updates...?

interesting i should find the thread. i have been looking for large esc/motors for a electric go-kart project. come on castle, make is 20s capable:intello:

+1


I would really like to see a 20S ESC :)

I have to ask it again, as I'm so curious to this ESC: any updates?

Sorry, still in the testing phase...

This is a big project, and will take a while. At SHV voltages, safety is a big concern.

Thanx!

Patrick

Can you give some info about the "low cost MMM" as mentioned on some other forum?

No -- no details available yet.

Wow!
The demand for high voltage is still growing.
Why couldn't castle had been around when I had the money to put into these?

Well, if you read the comments...

22A no load current is horrible. There is something wrong with the magnetic design of that motor. A motor of that size and kV should have a no-load current of around 1.5A or 2A... not 22A.

1KW of loss to eddy and hysteresis loss is just terrible.

Lets Just hope its 2.2... ;) But Seriously, any news you can shed on on this controller or and motors involved? I certainly would buy CC over (ed) HK anyday...
I need to power a E-Dirtboard. And rather use In-runner Via Chain/Sprocket. Maybe the MMMXL isnt enough... Although I have been thinking....:yipi:

Thank You!!:party:

If you think thats bad you should read the reviews on most of their HV controllers. A lot of people drop a couple hundred bucks on something that lasts no more than 1 minute. Needless to say I didnt see one good review.

When I get a chance I'm going to test my turnigy 85A vs the Castle 75 Ice and record some temps. The turnigy got to about 155 deg F in less than 45 seconds on a 40A load. I'm actually afraid to use it on my airplanes.

YIKES!!!! this is some gigantic stuff.....wow....

What would happen with the XL + 1717 on 8S in a Baja?

Vort3x, this thread is about Super High Voltage ESC's, but a few threads down is the 1/5th scale thread. You may get a better idea there :-)

P.s. I will be able to tell you what a 1518 on 8s will do in a hyper 7 soon, and 8s is too much for the 35k limit of the 1717. It's a 6s motor, 1580kv X 22.2v = 35,076 rpm

Oops. I think the RPM limit is 45k though.

On my 1717 I just received from Castle it's printed "35,000 RPM MAX" right on the rear plate... I'm sure it would spin 45k for a while though :-)

While the 1717 is a very powerful motor i do not think it is enough for the baja, unless you can make the baja alot lighter. Maybe we can start making a list of setups including vehicle weight and gearing for the various motors? That way it would be pretty easy to get an idea which motor would do well by comparing vehicle weight with a known working setup...

We have a small group of guys trying to make the motor better for light EV use (olaf is one of them). 22a no load is in fact accurate, and it seems to be a combination of terrible ring bearings and something else going on with the controllers. They are also having a helluva hard time controlling the motor, as the low inductance and resistance is just blowing up controllers left and right. 36 TO220 FET controllers are the latest "rage". The last test:

Max RPM: 6030
Volts: 76volts
Max current: 5.5 amps
No load Power: 240 watts

They are using sensored controllers like the little legged FET versions I showed you about a year ago, Pat. To get the current this low, they had to use a timing advancer to get 48 mechanical degrees of advance at the max rpm. Maybe that gives you clues on what is going on.


My 3230 Astro is much better quality :yes:. Too bad I got it wound for 50kv instead of 100. I will need 300v to start wringing it out :lol: If course I didn't want it for F1 performance, I just wanted a motor that wouldn't need a ton of gear reduction to run at 30mph.


You know where to reach me Pat, I stopped by yesterday but you were gone. I got to see some goodies that really gives me hope to get these fools away from legged FET packages. I know how much you LOVE TO220 dies :lol:

TO-220s have their applications... It's just not low resistance, low inductance, high voltage motors. :)

What would you consider a proper application for them? Is the thermal pathway a big enough consideration to give them an advantage on reliability or heat sinking?
