Now on ebay for anyone who is interested. I do have a pair of driveshafts too.
Thanks
Tim

Now £3000 or best offer.

Hi All If anyone is interested im selling this kit of unused parts for £3500 ono: Siemens motor, DMOC water cooled inverter, single ratio Borg Warner e-drive gearbox, motor to gearbox coupler, driveshafts & cooler (for motor and inverter) originally from an Azure Dynamics liquidation sale. cheer...

Thanks for the help everyone, particularly arber & Tom, seems that the encoder circuit and Olimex sensing is very sensitive and needs setting up depending on what encoder signal you have in single encoder mode. I thought it was plug and play, lol. My understanding of this now is that the Olimex ...

getting better. No encoder error now, and smooth starting. Now have a 6.8K Ohm pull down on encoder signal, with 10 kohm inline to olimex and 1.3 nanofarad cap to ground on the mainboard.
Hoping parameter settings are the reason for such slow max speed at full throttle.

Having had the wheels spin reasonably well with car on stands, albeit not with the smoothest starting, i cant seem to get the car going well with wheels on the ground? Played around with parameters fslipmin, fmin, slipstart etc.. quite a bit and still i get encoder error, despite signal being good?a...

Good news at last. I have smooth drive much higher rpm than before - not sure how high, but my battery test wires were getting a bit warm anyhow. T1 seemed ok via multimeter, so no idea what was causing that issue, so i decided to connect as Tom sketched and remove it anyway, the only difference i h...

Thanks Tom, might try going directly into the Olimex too. Had another go separating the encoder lines away from all the 3 phase connections and from all the inverter main boards other connections. Used 1.5k resistors and cap on encoder signal before T1 base. This appears to have reduced interference...

Good news Tom, hope the drive test works out too. Thanks for the link for coupler - didnt like the one in the box with my encoder and the info on your filtering. The Omron encoder i ordered turned up too, so i did try it and didnt get a big improvement and no more rpm, but im not sure it is the righ...

Thanks for all the replies, I will have to study these since im a beginner when it comes to electronics :) Tom3141 - I will try and get exact motor max rpm tomorrow with the 50 ppr encoder, perhaps you can send me your parameters and I can set exactly the same? I guess that my V1 board configuration...

Just had another go and found that the encoder channel connected to the inverter was not working, it does appear to be broken. So I took channel B which I showed on my last encoder signal video (used for my speedometer) which still worked with 5V signal output and connected it to the inverter instea...

Thanks arber333 & Tom. I will try manual mode again and measure the encoder signal at the transistor again, as it does make some sense a limited signal could be causing the problem without looking into the SW code. Last time I tried manual mode I got to 20Hz at the motor easily, but this doesn't...

Just tried fmin 0.05 and as much as I could think of changing that may influence the low rpm at full throttle. I have no idea what is going on, and I have had parameters set the same as 3 years ago when it all ran rather well https://www.youtube.com/watch?v=BD7ln4yzc4g. Theres only the odd parameter...

Thanks Tom Ive not measured rpm, but I rekon its 60 rpm at the wheels and yes it seems to be the limit, which is going to be around 500 rpm for the motor. No noise that I have noticed. The inverter seems to be very smooth, and I hardly get any whine now either, not sure if that's good or not? I have...

thanks arber. Unfortunately no luck with that, but it spins so I think boost is ok? I tried 18000 and it didn't go any quicker. Ive attached the parameters that I last tried, would greatly appreciate if those with more experience can have a look and spot any major reason why I cant get much more tha...

Instead of the 5V from sensor board that i was using, I found that a separate 5V power supply has made a huge difference, and now i get the inverter to respond smoothly and the encoder signal is clear. I used a bench power supply first, and i have one of these https://www.ebay.co.uk/itm/12V-to-5V-Du...

Hi
I would much appreciate the opportunity to buy 6 packs
cheers
Just to confirm 6 packs = 36 modules?

Sorry just 6 modules please

I don't understand what is going on, but I can see what seems to be a poor signal from the encoder? I did get smooth running in both manual unlimited frequency it seems, but only up to 1 or 2 Hz run mode via pedal for some reason, but then i keyed off and on and i couldnt even get manual mode to wor...

I now have my optical 50 ppr encoder and i didnt get much of a change with single encoder mode, but the reactions of the set up seem less violent. I get loads of strange noises (like the old internet dial up noise i think) from the inverter when it tries to run the motor which still barely turns, un...

that's promising news Tom. Im pleased to hear as i hope the 50 pulse encoder ive ordered helps me too. Have you tried running at 900 rpm driving? Im curious as to torsional resonance you can get in drivetrains and wonder if at 900 rpm you have hit a drivetrain natural frequency - the firing frequenc...

Took the Avago encoder off last night and could see it was indeed 256 pulses on the disc, all evenly spaced. 20200519_224310.jpg 20200519_224011.jpg 20200519_215234.jpg Perhaps 256 pulses and the slop in the drivetrain (im using original single reduction gearbox off the Edison van) will causes more ...

Cheers Guys The speedo uses the shell and needle of the original. The speedo utilises an Arduino Nano, Small LCD, and a Easydriver stepper motor board, driving a Switec X27 168 motor. Latest code and info here: https://github.com/TJH1981/Digital-Speedometer. The Code needs improving as if you loose ...

Hi Tom Please can you let me know what software version you use? Does it have the parameter encflt available as im sure this is what made my car drivable in the past. It would be fun to be able to drive the car again :-) With the software - 4.76 I cant set parameters to get the car driving. Im just ...

Looking more like encoder is indeed the issue following a few extra tests that I wanted to do to eliminate an IGBT being broken which is something I have previously experienced. - Manual mode with encoder disconnected - smooth start and rotations of motor achieved. - Manual mode with encoder connect...
