HI there I have seen some of these Remy HVH250 electric brushless motors advertised on Ebay and they sell for as low as 550$. It is a cartridge motor so it will need a housing but considering they sell new for 6000$ new... . I found also this one - http://www.ebay.co.uk/itm/REMY-ELEC...815?pt=LH_DefaultDomain_0&hash=item4180fb0957

They seem to have come out from BMW x6 hybrid cars and develop 90 hp when oil cooled.

Here is the link for the Ebay search

The question I have:

1. Can this motor be used as 20kW motor with air cooling or just a water cooling jacket by building a simple cage with bearings?
2. What controller would be suitable for a 20kW power when this motor is used?
3. Will it work with a lower voltage battery pack - 60-120V?

Cheers,

Daniel

Hi there!

As I remember these motors are used only with liquid cooling and 200-700V range, so in this case they are pretty much an overkill...

Thanks Ai,

I thought so too but if used with a 400v battery what would be the cheappest controller that can drive this motor?

Cheers,
Daniel

it would be some controllers from the junkyards, prius, leaf, X6 hybrids and etc, but it will require Eldis's UMC drive, keep an eye on his thread, it is really awesome.

That is great ... a couple of years and we will see prices drop ... drop ... drop. Thanks for that.

Thanks, Ai! I really appreciate your support!

This is exactly the thread I was looking for - I just scored locally two Remy motors from a hybrid Mercedes (most likely). I don't know anything about these motors - only that they are 40-50kg each, one has an external spline while the other just a hollow shaft (with spline inside).

The part numbers are:

A 722 340 00 16
Remy Hungary - 8900078
H24JL10A - 063038

And the other one:
A 722 540 34 88
Remy Hungary 8900012
H17AU10A - 113738

Any ideas about specs? Some manuals perhaps? I would like to test them out and include them on the list of supported motors. Of course this doesn't have very high priority, as I still have to manufacture enough of that damn thing! Holiday season is not helping either.

Hi Eldis,

Love your work

Hope it helps. Cheers,

Hi Eldis!

You can provide serials from these motors to the Remy inc directly and they will give the correct info about each motor. I have spoken to Thomas Boсkelmann [email protected] - and all He has asked were serials beginning from 890xxxx.
In the other way You can ask Chris Brune [email protected] - He also have some info and can ask Remy directly.

Hope this will help further more)))

 

[eldis]

Perfect, thanks guys! I knew I can rely on your expertise

I'll contact Remy directly, and see what comes out of it. These motors are small enough to be put on a permanent test bench, to do inverter performance verification and to see how well can the inverter auto-tune parameters (max torque per amp). These are very interesting IPM topology motors. They seem to be very torque-dense.

Of course some mechanical housing with oil cooling would have to be manufactured. Not my cup of tea (but will try anyway).

By the way it was announced last week that Borg Warner bought Remy International and like it often happens during such transactions they fired a bunch of people, including Thomas Boсkelmann mentionned above (confirmed by his linkedin profile).

Should you see a good deal for these motors, don't pass it since their future availability will depend on what BW wants to do with it. The production of the HVH line was allowed by DOE funding which is now expired, so it they don’t see a way to make profits with it, they might stop it.

That's bad news...

I Bought one of these remy motors last year, i also bought a Toyota highlander Inverter module with the intent on building my own controller to drive it based on Lebowski FOC,

There are now quite a few people in the same boat, which makes my life a great deal easier as programming is not my bag.
Now i have seen quite a few controllers that will easily connect, I am considering getting one of these UMC boards to drive it.

Do you think it would be a good idea to obtain another motor to use as a dyno?

 

[Ai!]

Ane of these motors will be very usefull as they are almost in every award winning EV or moto, rimac concept one, lightning bike f.e.

I think these motors are designed to work with oil as cooling fluid, and i think they have oil jacket in the stator side.
Any motor can work with any voltage, but expect less power proportional to the feeded voltage.
This motor is 200A Cont. 300A peak so you can expect something between 12-36KW in your case.
This motor is a great deal but that oil jacket complicates the system.

 

[eldis]

Unless someone can design a cheap and simple jacket for these cartridge motors, they are pretty much useless. Maybe Remy can provide some design files for a jacket reference design. For sure they have it and provide that to their customers.

i was planning on making a casting myself, there are oil inlet holes that run around the outside of the motor and there is an exit hole on the front bottom, il let you know how i get on, i have never done any casting before. the only other option is to machine one from a block or weld one from plate

this should give a rough idea:

Please make some shots with camera on the motor cooling, it's interesting is it with rotor cooling, or only stator cooling!?!?
Cheers.

 

[bigmotherwhale]

Its both, read this: http://www.neweagle.net/support/wiki...-9-25-2013.pdf

If you were to use this motor at low power levels then you might be able to get away without any oil cooling at all, unlikely for EV use however.

Not exactly cheap, but definitely not useless...

So on Tomdb's request, here are some more pictures of the Remy HVH motors. The dimensions are in cm, and the motors on the photos are always put such that larger motor is on the right.

https://www.dropbox.com/sh/cfzxcfexpr445px/AAC3xUOyPnDpuIG7KHJo5lWWa?dl=0

If you compare them with Hollie Maea's racing motor photo, you'll notice that the cooling flange doesn't look like a big deal (at least from outside it looks rather straight forward).

As I said before, these motors are not much of a priority for me - I have them to test out IPM control algorithms and auto-tuning of parameters.
Let me know what else would you like me to measure on the assembly - but contacting Remy about drawings might be a bit more useful
