Re: Internal dimensions of things in Prius transaxles
Two separate motors/inverters might be simpler to be honest. EDIT: Actually, what about an Outlander front transaxle/inverter. MG1 is connected to the ICE 'input', MG2 to the differential. They're only connected to each other if a hydraulic operated clutch is activated. The inverter is driven by CAN...

Re: IPM Motor Simulation and FOC Software
I span my motor with a drill and measured frequency and peak phase voltage
Although I'm never sure with these equations if they want phase-phase voltage or that imaginary DC equivalent...

Re: IPM Motor Simulation and FOC Software
Apparently, image.png where P is number of poles (or pole pairs?!) and Kb is the back emf constant (Volt seconds per radian - peak voltage divided by speed in rad/sec) Kb is easy enough to measure, as is pole count? But that's assuming that the above equation is correct (I can't find the derivation)

Re: IPM Motor Simulation and FOC Software
Built fine. A load of warnings (mostly 'depreciated') but that's probably a QT version thing. But it compiled and ran, and produced pretty graphs of control loops losing the will to live (You don't want any notes on tuning from me hahaha)

Re: 1971 GMCe Lexus GS450H BMW 530e Tesla Model S powered Electruck [FINISHED]
Looks like it's 'only' a brake reservoir?
Motorcycle reservoirs will probably fit the hose fine, but might be a little small.

Re: IPM Motor Simulation and FOC Software
Awesome work
I personally would have no problems treating the inverter/motor as a torque engine, but probably not ideal for the normal OI boards with throttle pots and all OI does have a 'min braking speed' (I forget the parameter name) though which cuts regen below a certain speed.

Re: Motor overload
Motor ratings will probably be thermal. You will have a max shaft torque, based on the mechanical strength of the rotor/windings/any couplings/gearboxes/etc. Unlikely to ever reach this... You will have a max shaft speed, based on bearing ratings, and hoop stress on the rotor (spin it fast enough, c...

Re: ESP32 Based Web Interface & Data Logger
Does seem to be the route of least resistance. I'm certainly no expert, but my first thought would be lib7zip or similar. Far too powerful, but open and multiplatform. They've put a lot of effort into showing many many points while keeping things quick! I understand none of that code haha I've only ...

Awesome, fantastic work :-) Ah, apologies, might have been the WIP v3 sigrok format that had units and scaling. Or I'm imagining things! Your app fixes the scaling though, and having 'V' floating around isn't the end of the world really. (Just name each 'channel' as "IDC (Amps)" or somethi...

Ah, gotcha. Sounds like it might be possible to create a '.sr' file with all the data and everything pre-set: https://sigrok.org/wiki/File_format:Sigrok/v2 I don't think the decoders can import (but could do the scaling perhaps). The csv import at least is in libsigrok, but it wouldn't be a massive ...

Yeah, part of the sigrok 'suite', I guess you'd call it a QT gui for libsigrok? Or a GUI that includes libsigrok in the Windows builds. Either way... :) Yeah, would be nice to import from csv without configuring anything. I'll look into it. Already found where to increase the max 'V/div' (https://gi...

Ah yes, good shout.
Good numbers
I think Johannes at least has been running a Prius inverter and transaxle, I'm sure there are a few others but can't think at the moment!

Got a small portion of the csv available? I might have a go at getting it readable in Pulseview when I get a chance.

Re: Lets get Damian a 3D printer
More than welcome, especially after all you've done for the community over the years.
1st task - start printing 3d printer parts at ~10x scale, then power each axis with Prius transaxles. You'll be able to print entire cars! hahaha
