LMX P2 : Freeride trials motorcycle frame development

Figured out the correct hall/phase connections.
No load current was 6.8Amps before. Now I am at 3 Amps at 54V, which is fine according to Revolt. The motor pulls like a tractor now and sounds way more smooth :D Will go up to 80V once I receive the 4th battery :).

For the interface I currently use a bearlabs BLE hooked up to a teensy 3.1 board via serial. I use a digital pot which the teensy sets depending on throttle pos I read in on another analog in. You can set this to smooth, fast...depending on amps etc....however...lot of stuff to play around with. I also read the voltage from where you usually connect Kellys beautiful analog meter to measure amps. Lock and unlock can be done via app and it logs measures/values to an SD card. Noticed too late that there is lots of flashmem on the teensy :)

Unfortunately wheather shall become bad. wanted to give it some tries at lake garda these days....

If you can share the "undocumented" protocol stuff PN that would be great help, as I am going the hard way: sniffing with portmon...
Details to follow.

Has this helped the heating issues you were having? does it stay cool after a few hard pulls?

Did similar interface for kelly serial a while ago. You can get almost everything from Kelly via some undocumented commands: Battery and phase currents, voltages, RPM, FET and motor temps. And program every parameter that can be programmed by Kelly software.
I am planning to use my old galaxy phone as a dedicated dashboard since it has a beautifull high contrast AMOLED screen.
In proggress of programming a dashboard app for my new 10kW Kelly.

Guys, I am VERY interested in getting some documentation on this project. As I understand it it would be possible to view all data and control ignitionn and power modes from an arduino with LCD shield, just by sending the rigths commands to the kelly. This would be huge. I'm ready to invest to get this developped.
:D
 
This thing looks perfect :
http://www.mouser.com/pdfdocs/4D_Systems_4DLCDM22DatasheetREV12.pdf
has allready microsd port for logging and resistive toutch screen
Now, we need someone to do the coding and RS232 debbugging as I'm more or less helpless with that part ;)
 
I have developed my own devices based on this platform. Look at myintelligym.com for example. I Can assist with your programming if you use that device. If you want some integrated board's with the usb programmer an accelerometer, real time clock and uSD card for storage let me know.

Your thing looks perfect for our needs andy, as I understand it is based on an arduino with toutch scren? it seems to have an integarded battery wich we won't need but I like the enclosure already.

>those things are so cheap, 2,4" lcd plus arduino would be less than 10$. Add 20$ for a high quality enclosure and you have a very nice product for kelly users!

Oh. I should have looked at your datasheet. Mine isn't quite the same. It does not rely in the arduino . But is directly programmable Using their 4dgl language

I'll dig up a link to a dashboard project I started on with my device.

I am currently logging the serial interface for understanding direct communication with the kelly, but I assume there will not be a lot of data available and writing or setting stuff maybe completely denied.
Thus I have a teensy board (or arduino) in-between the BT-module and the kelly which does the logic of throttle response measuring etc. based on this: http://www.raywenderlich.com/85900/arduino-tutorial-integrating-bluetooth-le-ios-swift.
I am only coding for iOS, not for android, but if you give me some input / requirements / ideas.... I have no issue to post an app.
I also started with a 2.8'' touchscreen, but honestly said the graphical power of an arduino is quite low and it should perform control tasks primarily, not nice graphics stuff. And...make that thing dust proof or water resistant...and controllable with gloves.. :cry:

The motor stays quite cool now at 55.5V. Will get the 4th battery by tomorrow. We have some days off from Thu to Sun here and I will give it some tests. Problem I faced yesterday...motor pulls the axle forward and the chain gets loose :). Need to fix this first.
 
3amps at 54V is even less than what they state for the RV120. Does the Pro have thinner lams and lower no load current?

Is there any guesswork on the Kelly UART already? What do i have to send, what may i receive, at what baud rate and so on? Please post something about it, i am really keen. Just make a new thread in the motor tec area http://endless-sphere.com/forums/viewforum.php?f=30 like "Kelly UART Read out" Thanks for posting this stuff! I really want to try that. Just dunno where to begin
 
So does anyone have an opinion....

BHT vs Revolt 120......FIGHT!
 
BHT super easy to fit, sealed, lower kv, cheap, lowish quailty.
Revolt more max power, higher kv, better efficiency, not easy to mount, unsealed, somewhat expensive.
 
Absolutely nothing to add. DEHiCKA wanted to provide some baseline info for further serial sniffing. Will create a new thread and post some overview of it, or better said: My workaround :D

Well if you are looking purely for max power Revolt is the winner - at least on paper. Revolt 120 got more then twice the peak power over the BHT. But real world trials might turn out different. There are not yet much info about the revolt motors here on the forum. So it is difficult to judge only by paper claims.

Revolt with hall's and max-e controller should be able to do bursts of 15+kw power. Then you got to ask yourself, do you really need that much power? If the answer is yes go for the most powerful one :D From what I've read so far the BHT is a torque monster and performs great as a daily driver, but are you sure you will get by with less power? I would expect the revolt to beat the BHT in acceleration and top speed - a side by side test ride would be awesome. Or getting the BHT and revolt added to the simulator.........

Hehe you are correct Allex, and I had to make changes in my previous post to reflect that.
It is never enough power :twisted:

9 inner holes for M4 bolts to the hub (into the right side spokes flange of the hub), 18 outer holes for the spokes. six holes at 5.25" BCD for the #219 sprocket

interesting... that arrangement would put about half the torque directly into the spokes (and into the rim). the other half through the other flange.

seems like it would work. has anyone tried this before?

1019-4187-full-zzzzm525rear_discsil-14.jpg


this hub has tall flanges. how about mounting the sprocket adapter onto the flange using those 18 holes? and drill a few more into the flange for good measure. then just use shorter spokes for that side
 
revolt and big block both have cheap .5mm lams. why pay a lot for a motor with cheap lams? there is no alternative motor of that size+power that has halls mounted and is controller friendly. If the revolt had thinner lams.. still no answer if the Pro Version has?

This hub flange thing was just an idea, i never tried. Most cheap method i can see. I would use a hub with 12mm shaft, not the squashy 9mm quick release type
 
for those not following the whole facebook thing, we got new proto frames in and we will get a batch made mid June so if you want a frame shoot me a PM ;) I try to keep track of people that contacted me about those but it's not always easy with facebook, ES usernames and email :roll: Also we will have LMX dual ISO 6h hubs in stock foy your guys custom builds!

Revolt are using the 0.3mm lams on the 100 pro version motor and plan on using 0.3mm lams on a new 160 motor :shock: . I am extremely interested now :D . No plans on the 120 pro to use 0.3 lams at this time as they feel they will not impact the efficiency much.

I wonder what the 160 motor will weigh and what peak power will be. If they can keep that motor under 8 kilo and with 20+ kw peak I am sure that will be a true monster. Didn't see any news on the revolt site about that 160 motor - do you know more details about launch date or specs?
