Well be carefull when inserting driveshafts. I replaced my RH seal and it looks like i just nicked the edge of it with sharp edge of the shaft snap ring. That steel wire at the end of the shaft will rattle and jump around when inserting the shaft. To stop it from damaging the second seal i put some nonacid grease on it which heped to stick it to its groove...

Hi
I have inverter with the socket missing does any one know the wire colour i should use ?
Thanks

Could you explain the essence of your question? what exactly is not clear to you- where are the +/- high-voltage batteries or thin wires and the desire to control over the can bus?

For example, I control these inverters only with OI v3 johu boards and in my opinion this is the best solution!

The rule is to connect positive to the side of fuses. That is the HV+ side.

You can see my build https://mazdamx3ev.wordpress.com/2023/1 ... -assembly/
Notice the purple printed socket, that is the positive line.

How does that work? So you use the small board V3 with its I/O interface as VCU directly wired INSIDE inverter casing?
Or do you build your own VCU case? Some photos please.

pay attention to the 0.1 uf condenser mounted on the shutter and the GND . this gives a delay in switching on the contactor and it OVERCAME the problem of arbitrarily turning on the contactor for a fraction of a second when 12 volts are supplied.

Oh... you need to load those photos as attachments.
Otherwise good point i was annoyed by relay chatter myself and i simply had to pull 12V for running contactors from a different source.
edit: Maybe you can post link to your webpage? It is just my curiosity as i was thinking of using the STM chip for a simple VCU and i see V3 has everything there already.

I removed the wrong messages by cleaning this page))

if there is no text, then everything worked out. strange.

Ok, now you surprised me.
So you are using OI V3 board as control brain? Do you have a wiring how to connect to Outlander power section on the inside?
EDIT: This would mean you can get 100kW from the motor for sure!!!

tnx

Even more! I have recorded 127 kW on the wattmeter!

WoW really nice! So that white connector is drivers...
Some questions:
1. are the transistor signals positive or open collector?
2. Do you use transistor fault signal for anything?
3. Do you use resolver with OI or do you leave it connected to outlander control board?
4. How is HV signal read? Is it 5V analog signal or do you require any special signal?

tnx for data

1) The control signal is negative
2) no, I have not found how to use desat
3) I connect the resolver to the johu board
4) high voltage is one wire, it can be seen in the photo (connected to the yellow wire) and it is signed by me on the diagram.

Wow, you really love pushing stuff to the limits!
Fair play mate - I'd appreciate if you could put a more detailed instruction into the Wiki and/or post a video of this?
How is the accelaration from a dead stop vs OEM?

You made my day with this - in my mind the Outlander rear including diff is now a safe option for medium sized conversions as a "performance unlock" is possible

hi
The Can Bus and low voltage I have the following wire colours green,black,white,grey,violet,blue,yellow,brown,orange?

Slow down guys. I expect some vibrations at the slow end of RPM as usual from OI. Also you need to do a good resolver zeroing as OI has its own interface.

OEM interface is really smooth and for comfortable ride i suspect OEM control will be better. But for sporty conversion...127kW seems too much for that small motor .

And also dont forget you can drive ANY PMSM with outlander inverter and that OI board. This just makes my spare parts stock larger .

I went to learn English, or someone forgot Russian.

Hi just want to clarify point (2)... As I'm aware we can get confused when we all try to write in our non native language...

You have either:

(a) not found any signal yet that goes high/low during desat and your essentially running the inverter blind (from a desat point of view).

(B) The drivers self shutdown on a de sat occurance.

item "a".
