Thanks. I'll compare it with my own. Two questions: Why are the specified values of sincosofs here? What is the firmware version? I see that it's old, but what is it? I had 5.20 sinus used and I didn't have the parameter of the maximum phase current. sincosofs is selected for a soft start of the en...

I have such settings, but it's for a 135 volt battery

OK, I'll post them here

and here is the second device on stm32, I almost wrote the program code, it remains to debug a little, the problem is that the tachometer sometimes jumps, I'll deal with it later

you will also need the mc2515 modules

and arduino nano

Here is the code for arduino

I made the first device on arduino, I can put all the material on it here, the minus is that it does not always read can, I am currently developing the second device on stm32

hi. I also ran into such a problem on my Audi a4, I put together a device that listens to can and translates into a meander with a frequency that varies depending on the RPM

I also had something similar, most likely the modules do not pull current. How do you have the engine turned on in a star or in a triangle?

Нi. There is a factory inverter with an IPM engine with a capacity of 160 kilowatts. Everything is built into one housing, which is convenient for installation in a car. My friend asked me for help with starting the inverter, it works through the can bus. There is a document with can messages, someo...

You can compile the firmware in hex format. I still haven't figure out how to download the firmware in bin format

the switching circuit, which can be recalculated for its power

I can offer the board of the generator, which is specially made for the task of the inverter

I opened the inverter, and I could not find a drop of water in it, one of my friends said that there might not be enough capacitance of capacitors in the inverter, when the cold increases the load

Have you tried feeding +12-14V to the start input?

At first glance, there is no error in the parameters, everything should work. The switching voltage of the contactor you have is 0

Thank you for developing the source code. I have been raising a topic on the forum related to asynchronous motor current control for a long time. This year I plan to build several projects and test your firmware. The bad news is that my car was at an intersection, and the transistors broke through, ...

Take a photo of the remaining parameters of the inverter, as well as the diagnostic parameters that are at the very bottom

After the conversion, I drove 1000 km, but as the cold weather came, the inverter started to malfunction, there were two times, I switched to protection. The day before yesterday, the protection worked and I stayed on the road, 1 transistor broke through. I ask for help from the society, what could ...

Hi. You can compile the source code. I want to try it in my work too.

so there are several wires wound up there

The winding is applied two-layer

Romale wrote: ↑Fri Oct 14, 2022 8:23 pm 3 parallels?? and what is the cross-section of one wiring? it is difficult to wind a good amount of cross section with very thick wires

I don't remember exactly anymore, it seemed to have a diameter of 0.67 мм

On the second, it accelerates faster, but up to 40 km per hour, then sluggish acceleration

Romale wrote: ↑Thu Oct 13, 2022 9:04 pm which controller is used with this and can you attach your settings file? have you thought to raise the voltage twice at least?

Controller with 12 mosfet IRFP4668, so the voltage will not be raised, they are only 200 volts.
I will publish the settings file later
