As I don't have too much time to reply to requests I uploaded the schematic and gerber files so you can build it yourselves. Note that the MCU LPC11C24 is now obsolete, but it still can be found at Aliexpress in small quantities www.sportdevices.com/uploads/pics/CAN-OBDII_schematic.png...

I am sorry for the big delay. I built several PCBs, in case someone is interested

Thanks for quick reply. I already contacted Luna to ask about Phaserunner, they say it will not work. The connector has all not used wires cut at about 1 cm, they could be eventually connected or replaced, but without the software it does not make any sense for this project. I am using a VESC...

I also have a problem with BAC800 settings, I bought a BAC800 from Luna customized for Cyclone 3KW motor, but it comes without the brake potentiometer cable, and they say they cannot enable this function! (but they do not warn about this in their web page) How could I get a BacDoor SW (even an...

Offtopic: Testing an ebike with Cyclone 3000W motor and VESC (50V, 60A limit) on dyno: comparison of FOC (2.2 KW / 3 HP) vs BLDC (1.7 KW / 2.3 HP). It seems like the battery current limit is applied to BLDC mode (flat section), but not to FOC mode (any ideas?) any thread to post this?

after too long waiting for PCBs we already have the definitive version, with DC/DC converter (24v to 5V) and two CAN inputs (same bus), one non-isolated for SEVCON/Curtis, and the other Isolated for BMS (sorry for the bad hand soldering, production parts will be done at oven) (Note that this...

It sounds good, do you have more information? involved hardware, etc anyway my device also acquires data from the BMS (CAN) to send to the mobile phone, but I admit that it a bit heavy (too much BMS channels) for the way that 'Torque' works. It would need a special bars-array to show the whole...

and with http? (instead https) here is a video with the GM (induction) motor: PES5hT-3nF0 it is basically a truck eddy current brake (small size, less than 1000 N*m) with two semi-axles installed and connected to the motor with sprockets and a chain. For measuring torque the system uses a...

cannot open those links? https://www.sportdevices.com/uploads/pics/ME1304_40HP.png

Finally I did the "last" test, 100V just charged and cool morning (and motor): I increased the mod. index to 95%, and it gave 39.9 HP at brake, and about 42.5 HP at motor (estimated). I is about 2.5 HP more than the last test, but the torque and HP graphs changed a lot. Actually TQ has the same...

8 x lipo 16ah x 22,2v 10c. Total 100v, 3kwh, max 320 a

Wow, it is complicated. No enough battery and no coolling yet. At the moment it gets hot in seconds I will do a log when I test it in the kart. Mainly for temp

ok, I'll try next Monday. Today I expent almost all day charging the batteries with the "Lipro" chargers (12 x 6S x 16Ah), and tomorrow is a holliday here. But I think it should give some extra power.

ah, ok. It makes sense if I do the calculation for W rad dividing by 2 (4 poles?) and Veff / 2, it shows about 0.031, but it is approximated when reviewing old logs the Ke changes across the log, but values are close to 0.029 most time Last time I measured it it showed 0.0299, but I can measure...

66 mH vs 69.9 mH seems ok Ke=0.021 vs 0.029 has more discrepancy. I measured the Ke value with DVT (VCI 3, Tool 25.6, Tcl patch level: 8.5.18) how should I verify Ke? it is supposed to be the V RMS voltage / rad/s, isn't it? For instance (95V / 1,42) / 5000 RPM / (60 / 2 PI) ? (if 5000 RPM is...
