Thanks, that must have been some detective work.

I can see me replacing it with a waterproof cable gland and feeding the cable up to the inverter.

I just read the part number off the connector under my binocular microscope! That way I could see that the '6' was in fact a 'G' and got the right result.

It may come to that! I was about to place an order with Digikey when I remembered that the terminals are not included. Up until this point it looked like the connectors would have been quite reasonably priced. The terminals weren't expensive either, about 4p each...

But the order multiple was Ten Thousand!

I got this resolver setup in my harness

R12 - 35,5R Black, White
S13 - 86,4R Green, Red
S24 - 78,5R Yelow, Blue

I do have one question I'm hoping someone will know the answer to: I can see Damian's 450H inverter control box is capable of driving the GS450H inverter and therefore transmission. Perhaps I'm taking too simplistic a view on this, but would the 450h inverter with Damian's control board be able to drive the Outlander rear motor OK, or would I be better with the Prius Gen3 inverter with Damian's logic board?

Guessing it comes somewhat down to the resolver and winding configuration, although looks like the resolver is the same part as the Prius, right? Alternatively, would the 450h inverter drive the GX450h rear diff?

Thanks for any info, look forward to following developments!

Welcome Scott, and do you mean would the 450h inverter drive the Outlander rear motor, and would it drive the RX450h rear diff? (no such thing as a GX450h).There will be others here can advise - I'm sitting back and learning! Best way to ask such questions is to start your own thread in General rather than piggyback on an existing thread I suspect...

Hi

Anyone figured out Outlander rear motor pole count?
I am guessing at 10poles, but it keeps jumping when i try to run it.
Resolver travel is also not smooth enough regarding previous Remy HVH250 motor.

tnx

I'll add my resolver to the list,
35.7R Black, White
85.0R Green, Red
77.2R Yelow, Blue

Sadly I spotted moisture damage on the resolver connector so I'll be abandoning it for some other solution.
The photo does not show up the tell-tale blue/green powder indicating corrosion of the crimp connector. This might explain why the motor was for sale on ebay without a gearbox attached. Although I didn't spot that until after I bodged up a connector for testing and is not intended for any serious use.
I noticed the connector pitch was 2.54mm x 5.02mm which matches the holes in prototyping board and plenty of PCB connectors.
the pins are flat plate rather than a square pin so rather fragile when bodging anything to them. An IC socket grips the pins whereas the other connector of the sort you have around the edge of an Arduino did not because the pins are flat plate rather than a square section pin. I'll reinforce this is not a long term or serious solution and just for testing.
I thought I'd share this as no one has found a replacement connector yet.

Well i can confirm now...
Outlander rear motor is in fact 10 pole motor
It is equipped with 10 pole resolver.
I ran it with Johannes inverter and i didnt have any problems with jumpiness.
I was cautious at first when i was setting up resolver offset. Just in case... It did only take 3A id current to rotate and when i found 15000pt it stopped rotating.
For this video i have rpm limit at 200Hz (2500rpm), later i rotated at 400Hz (4800rpm) and later 600Hz (7600rpm)
EDIT: above 400Hz in reverse i can feel some rough running. One time at 800Hz in reverse it also tripped OC limit!

I think it would be safe to add parameter "reverse speed limit [Hz]" Johannes!

Now that looks great, time to get this into a setup where you can start loading up the motor.

Sadly i dont expect this motor to go into any car soon. It will remain as my test bed for testing various inverters.
I will try rear inverter CAN control with it as soon as i receive the inverter here...

Next will be dual IGBT Volt inverter drive! I need 1000A out of my Volt inverter .
Then inverter goes into my Pug to drive a Leaf motor!

I've found the Hirose sample request page. I've had overall good results when requesting samples like this from companies that have special lines made to order etc. I won't be following it up myself as my motor has water damage and visible corrosion in the socket so it's going to be easier for me to simply replace it all.

Theese are my parameters to drive Outlander motor using Ampera inverter with resolver.
Whoever will use my parameters needs to consider next....

1. Current sensors are from Ampera inverter. I use 3pt gain
2. Voltage is 370Vdc, current settings are up to 500A, but i dont see more than 50Arms when starting
3. Resolver is native 10 pole. Motor is 10pole as well so you need to set 5 pole pairs for both.
4. Syncoffset for my motor is cca 15000 which is natiuve to that motor. Still there is enough similarity in other pictures that it is a safe bet to try this.

I am certain there is more... it will come to me.

Has anyone found a source for those connectors so far? I just got quoted 150 quid for one by a breakers.

If not I'll try and look into it. Maybe get a bulk order for all those who follow.

Have you tried the samples form I linked to a couple of posts above? (You might have to register an account)
Most companies are quite generous with handing out samples in 1s and 2s and I've been able to repair odd equipment using them including a smd 50way breakout connector for the Toyota inverter board, however not tried it with this company.

Personally I'm not going down that route as the connector on my motor is water damaged and I'm going to replace it with a gland and cable into the motor as I cant justify replacing both and keeping it standard for the sake of it.

I did take a look at that link, but unfortunately it looks like it's only for North and South America. Cable and gland does seem like a good option.

I see i could easily make a new flat plug and put 8 pin Liycy cable through it. It would work on both sides. It would require to make a circular plug on a lathe and make a groove for O ring. Then i could use a large flat washer to hold the plug down against the casing. It is the same connector on both sides so i would just use a through cable and 8pin sealed connector here.

Oh that's a disappointment, I didn't take it that far and just assumed it was global.

Arber333 sounds like he has a good plan for an alternative solution.

As previously stated, the connector housings are available from Digikey and Mouser, however the pins are only available in multiples of 10,000.

How many of us want connectors for these we could do a lot of conversions with 10k pins

On a more serious note I bought some of the connectors a few months back still waiting I presume the 16 weeks will be extended too because of this corona I will try a few pins off other connectors when they eventually arrive!

I went down the Liycy cable route in the end. Designed new cover to replace the original connector that will fit an m12 cable gland. Uses the original O ring to seal.
I'll test fit this on the weekend and update this post.
Edit: It fits really well!

STL file is here if anyone wants to try it first. https://www.thingiverse.com/thing:4557232

Also hoping to have this running from a Prius gen 2 inverter this weekend. Updates to follow...

I have the motor running on the Prius gen 2 inverter. This is just in manual mode for now. Still need to tune it all in and get the throttle plugged in.

But it seems quite smooth once it's moving.

Thats great! I like to watch all types of salvaged parts come to a new life as "hybrids"

great work on getting the motor turning, what are you using for power? have you got a battery pack or running it from a lab power pack?

I have it hooked up to the 48v battery in my quad bike. It's the highest voltage battery I have and it means I can also use the precharge system without having to make one up for it.

Again great work, perhaps you can help me.

I Also hookup up my Outlander rear motor and Gen2 inverter on FOC, but struggling to get the resolverd wired correctly.
today the motor gives a shock one time and then inverter starts to make sound with drawing a lot of current from battery. I used the resolver pinout from Arber333.
How to determine the + and - so to say (or the right phasing) about the resolver?
for example did you tight green and yellow together on pin 2 or red and blue together on pin 2?

I'll take a look tomorrow when I am there and get back to you on that. I can't remember off the top of my head.
I found that on throttle my motor is a bit more unsteady, it will also sometimes not move and draw a bit of current. But I am not sure how much of that is to do with the PWM wires on the control board being wired wrong at the moment.
