Mitsubishi Outlander rear axle

[arber333]

I have decided to start a new thread for Mitsubishi Outlander rear motor and diff axle here.
Those devices are affordable at some 400€ with differential unit. Also it seems they are quite plentifull online.

I will repost some of my finds here if anyone find it interesting.
Also if you have some more info on rear axle please share.

Johannes can you make a Mitsubishi Topic and put this thread in and move posts from Toyota MGR here: p3550, p3607, p3610, p3614, p3615?

tnx

I think it is 60 kW - 195 Nm thing. Plenty of power for 1t vehicle.

See here some specs etc... I havent seen any report on teardown or technical...

It sseems Mitsubishi motor can go up to 130Km/h on pure EV with some add-on. So motor is capable.

I just bought one to investigate

Nice, I have enough hardware at home to buy one now, but I can assist you if you need some help. What inverter will you be using?
I consider following details important:
1. Motor pole count
2. Resolver wiring and temp probe
3. Any mechanical devices on the motor we can use, like park brake?
4. Phase Cable dimension, are they 25mm2 or 35mm2. If they are 50mm2 i can assume motor will give 100kW with good battery.
5. Measure motor resistance across two phases. Leaf value to run FOC is 48ohm at PWM resistance, but true resistance measures some 10ohm.
6. Motor inductance between two phases, i see Leaf motor uses 178uH per phase.

Picture of resolver. Part number search doesn't bring up any exact matches.

Can't see the picture

[SciroccoEV]

Try now

Better. Do you have a picture of the resolver core?
And maybe resistances of the various coils. I'm guessing all resolvers work the same, only a matter of maybe adjusting the excitation amplitude to get a good output.

[SciroccoEV]

I'll get some more pictures tomorrow. I took that one to get the part number, hoping to just look it up. The part code format is similar to SmartSyn resolvers.

[SciroccoEV]

There appear to be two temperature sensors, judging by the four wires.

Resolver has the expected six wires for exciter coil and sine/cosine.

The trusty Fluke 77 essentially read a dead short on the phase windings. It will be a while before I can get it onto the bench and pass a few amps through a phase to read a voltage drop.

Yeah looks just like Nissans Resolver just with a plastic cover. Also matches the 4 pole pairs of the motor I suppose.

[arber333]

Yes however Leaf resolver is fixed. This one looks like its position can be reset.

[SciroccoEV]

My scales say a fraction over 40Kg for the motor alone.

[johu]

Yes however Leaf resolver is fixed. This one looks like its position can be reset.

Indeed. Well, don't touch it, then (unless you find mechanical adjustment better than software adjustment)

That's what witness marks are for!

[arber333]

Maybe use some nail polish over the fittings to mark its original position? If you absolutely have to move it.

A little more information;

Resolver connections

Green - White 33.8 ohm
Black - Red 81.1 ohm
Blue - Yellow 73.7 ohm

That suggests that Green - White as the primary, but with a bit more variation in the secondary resistances than I might have expected.

Hi all, I stumbled across this thread after posting the outlander rear diff on one of the Facebook discussion groups.
I'm looking into the use of using this drivetrain in a classic mini and have picked one up to test the fit.
I'm not very good at electronics so on a massive learning curve. If I can help in anyway please let me know but I am literally starting from scratch.
Cheers.

Hi Gaz,
Interesting project. Where are you up to now? How can I get info on your progressions?
Thanks, BR, Xavier

Im currently building the subframe jig so i can hold the front subframe in position, and Ive got the first design of the mounts designed up.
Have a look at my instagram electricclassicminis to see the photos.

Ive found out that someone in the UK is using the Axiom controller board to replace the standard one in the outlander HPEV but ive not been able to make direct contact with him.

I've just found out the Mitsubishi Outlander MGR has a ratio of 7.065.
Knowing this allows for better search hits when looking for technical details. But I don't have time just at the moment to put much more effort into sifting through them all for ones worthy of posting here.

Is there any Outlander rear axle motor spinning here with openinverter or the original phev inverter? Or other?

Have you got it spinning? I wonder If Leaf inverter with Johu board could work with the Outlander rear motor.

Hi All,

Just to introduce myself, I'm an OEM Electrical Systems engineer, and am now embarking on getting into EV conversions as personal projects. Got to say, super impressed with all the progress that's been made to reverse engineer these components and put them to good use for conversions - top marks for reuse and recycle! I will be keen to get involved in testing/development once I've moved house and got a workshop set up.

Think I've managed to read and watch all nearly all the information available now, and trying to put together in my head a conversion strategy possibly using the Outlander rear diff too.

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!

Trying to track down a matching connector for the resolver/temp sensors.

It's a Hirose GT18WB-14DS-HU. Digikey and Mouser both list it, but with longish lead times. I've also found it at specialist automotive connector suppliers, but also only to order.
