openinverter forum

Hi all, i haven’t been able to find any even approximate physical dimensions for the motor/ inverter/ pdm stack, could anyone help me out?

I've come up with some approximate dimensions, incase anyone finds this usefull

Width: 53cm
Height: 82cm
Length: 50cm

Only approximate guestimates but useful for a basic 3d mockup

From another thread. Receiving this and dragging it here to try to keep it a bit cleaner.

Thanks

My wife bought a 2019 160kw / 62kwh Leaf (gen 3 inverter.) it's staying stock.

Not sure why these flipped...

The top width is from the parking actuator? to the right side motor mount.
The tall 69cm / 27" height is to the belly pan.

Thanks JRBE!

It’s not completely clear to me but appreciate you sharing. It looks to me like I might expect later gen PDM to be 245mm high. Although yours is in situ in the vehicle from what I can tell. So hard to be 100% sure where the measuring point is starting. But it’s a good start.

Thank you.

I have another query out there and I’ll add confirmation here if that comes through.

Yeah it's in the car, makes it tough to get a good picture. Measurements are from the dots of each layer (bosses to top cover.)
Without scribbles,

I just asked this question on my own project thread, but am repeating it here aswell. I have this photo from eBay of a Leaf PDM, but I dont recognise the shape.

But it has just occurred to me that perhaps this is what is hidden underneath the black plastic of the later PDM?

Please can someone confirm or deny? Looking at the various connections it seems to have what you’d expect on a Leaf PDM.

If anyone is familiar with this thing and can measure accurately the height that would be useful.
EBay link to EV Breakers. They actually have posted 3 of these.

Yes this is what's underneath the black plastic but this is the latest what I call a gen4 unit. I have those for sale too, they come from 2023 and onwards Nissan Leafs and are made by Toyota. They are the smallest so far but I have tested them and found them not working with ZombieVCU. So the controlls are different. The inverter itself also did not work. I have posted CAN logs on the forum for somebody to take a look. Your best bet is to have a gen3 PDM for now.

Gen3 PDM height (not the one in the photo) is ~21cm without the black plastic cover.

Very useful thank you.

You mentioned the gen4 not being compatible with zombie, also useful info. In my case, im using Resolve-EV, so im going to hold fire on any decisions until I hear back incase they support the gen4.

Much appreciated.

That looks like the same as the 2023 62Kwh PDM< I have on a recent car we have in the workshop, have powered with Resolve but with older SW and some issues, but may be resolved with a FW Update

Ok, that sounds promising. Has Isak / Resolve given you any firm commitment on looking at it or fixing it?

Am I right in thinking the latest PDM does not provide Chademo rapid charging via Resolve?

I haven't contacted Isak, but I see that there's a FW Update available, it works of sorts but keeps revs up when you go over a certain threshold, seemed to work OK with the 2019 40Kwh I ran it on before, which had a Torque Trends box attached, will keep you posted.

I’ve seen that revs thing. But it was on my 2014 Leaf, and with whatever Resolve version was shipped out about 6 months ago. I asked Isak about it. He did talk about a newer version which I didn’t put on yet. When I reported it, it was with a bench test, so no vehicle load. Having put that original version into a vehicle I can see that the continuous revving isn’t really a problem. Friction and vehicle weight beats the motor’s motion.

So I don’t know what difference the latest version makes. Shame the small display does not state version number when it starts up, I have no idea what I’ve got!
