Could a non linear throttle ramp could be helpful giving finer control of light throttle

Cool, yes make sense I get a similar effect at very low rpm pulling away, if you don’t accelerate through it you can set up an oscillation though the drivetrain

Just set temperature de rating in software as high as possible, the hardware is smart enough to over temperature derate

Looks like potnom oscillates at the same time? So software based issue and the inverter is just doing as commanded?

Wow any sign it was doing this was it noisy from the start? Makes me wonder what mine is doing 3k plus miles later

Wow has that stripped the output shaft on the motor?

Looks like every example I can find of sine parameters sets resolver pole pairs to 1

You could just scope the encoder output and count the number of pulses through 1 revolution, not sure what to set resolver pole pairs to when using an encoder.

64 pulses per revolution

Change numimp to 64

What are the specs of your encoder?

You may require slightly different gains thanks to less than identical component layout? (Just guessing) I’d verify with a current clamp.

Also worth graphing position

Looks like this won’t be an option for me as the longest ratio rx8 diff is 4.3! Lol will be interesting to see what top end you manage

Impressive, with my gearbox making noise this could be an option

So good news bad news….. Good news is I can no longer hear how many teeth the diff crown wheel has under regen. Bad news is the diff can’t have been the only thing making a noise so I suspect the gearbox isn’t the healthiest. So that leads to the question find another gearbox or ditch the whole moto...

Finally found a weekend to pull out and replace the diff that’s been complaining louder and louder over the last 3000 miles, new wheel bearings too while I’m at it

MIVB and MIWB can just remain unconnected at the inverter end. Not an expert with some firmware as I’ve never used it, I thought the v/hz based firmware doesn’t require current sensor feedback? Using an encoder gives actual rotor speed feedback probably means slip angle can me monitored again no exp...

I have sent pm

Is that square tube clear of the inner c/v?

I will take the 3D printed plug if it’s still available?

Nice work as always

Fair enough, I was just reading up on Toyota sync serial comms and thought of you, reason being I have an rx450h inverter here that I’d like to get working via serial. Not sure how feasible finding the ham commands without a working car to log is going to be, if I do get it working, (I have a spare ...

about halfway down this page https://openinverter.org/forum/viewtopic.php?t=205&hilit=gs450h+inverter+communication&start=75 arturk mentions he's having difficulty with reverse, using a prius gen3 on gs450 motor a couple of pages later: I did test few things and wanted to share my findings. ...

I know this many be a little late but I was reading the gs450h inverter communication thread yesterday and picked up on someone having similar problems to what you encountered when trying to use a Prius gen3 inverter to drive a gs450 motor, turns out the wiring diagram’s for the Prius inverter had c...

A flat floor has been on my to do list for far too long. It should make a real difference

I was wondering about an accumulator, but without knowing the flow rate of the valve body it would be hard to appropriately size, and yes you’d have 1 shot at pulling away and need to continue moving to refill it, stop start traffic would be impossible. I think the only solution is keep the pump or ...
