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

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

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....

Thank You!!

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.

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

. Too bad I got it wound for 50kv instead of 100. I will need 300v to start wringing it out

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

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

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

Pdelcast · 12.14.2010, 05:21 PM

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!

I know, I know.. it will take a while till this ESC will be released but are there maybe any updates? I'm sooo curious

Btw; Castleprojects.com is down?
