I recognize some of the motors and transaxles shown in the PDF file links. Some of the products are listed on Alibaba and are being sold by folks in australia. This is a real company, but I didn't realize their product range was so wide.
Efiero, is there any news from this?
I wouldn't worry about shipping cost. Remember it was a mere $300 to have my battery pack shipped from china by sea. This motor will not be as large or heavy and when you consider the fact that these are LIQUID cooled motors, this could certainly be a good find.

I might just try that. In the mean time, I found the main company website:
http://www.china-electricmotor.com/
Here's the brushless motors:
http://www.china-electricmotor.com/Products.asp?BigClassName=Brushless%20Motors&Smallclassname=DC%20Brushless%20Motors
If you look at the listings for the blue motors (AC or DC brushless), you'll find that the least efficient motors are still at least 92% efficient even in the fractional Hp range, with the high end comming close to 97%........yummy.......
From what I can tell this company is an apointed exporter for dozens, perhaps hundreds, of motor manufacturers in china. Not unlike what Sino Rich Group is for the battery company I got my lithiums from. Just have to fugure out if there is a better person or division to contact within the group. They don't seem to be on alibaba, but are on other B2B websites.

Anyone up for a group buy (or at least two people)? I have been looking at these myself, as I want to go with BLDC. These prices are reasonable and the specs look good. My main concerns at this point are shipping costs and contact infromation in case the stuff turns out to be junk (which I hope is not the case).
Also, do these have regen and a regen switch built in? I looked, but did not see... Regen is really something that I want to do, and it is relatively easy with BLDC.
I like the DL144-15.0B3 motor and corresponding controller (DCBL144-14.0B3); 144V, 15kW...those are exactly what I need.

I would probably be in on any group buy, but some one still has to extablish contact with them first. The cool reception that Efiero got so far is not encouraging. I sent an inquiry and have yet to hear back from them.
I've been reading up on the specs for some of their systems and these are mostly industrial motors, but some are also intended for mobile traction.

I have emailed them, and got similar info as to what was already given. At this point, it does not look like their controllers have regen. They are also twice as expensive as a similar Kelly controller I am looking at (KBL12401H) http://www.kellycontroller.com/mot/Brushless-DC-Motor-Controller.html.
I am thinking about buying the DL-15B5 motor from M&C and the controller from Kelly.
I emailed M&C about warranty and returns about 10 min ago. I will post their response.

Good morning, all. Here is the reply regarding warranty from M&C:
Dear Mr Joshua Nelson,
1.Motor and controller ,quality warranty 1 year.(remarks:not man broken)
2.Warranty policy:
a)We will complete some wearing parts for your changing in case these parts on the motor was broken. eg.Accelerator,Pedal plate,electric relay....
b)Order quantity more than 50 pcs,(2% * order quantity) pcs will be shipped together as backup.
eg,If purcase quantity reach 50 pcs,we will send one more as backup in case of any piece is broken.
c) Within 1 year,if any quality problem occurs,we will bear repair even change. The customer will bear the freight charge send back to us ,We will bear the freight charge resend to customer.
The above information is as the warranty policy for our brushless motor and controller
Any further demand or request please contact me
Hope our service is favorable for you
Looking forward to your reply
Thanks
Best regards
Not unfavorable, but not stellar--what I expected.
At this point, I am planning to order one of these motors. I need to check the wiring on the hal effect output device.

Just purchased this morning. They have a Paypal account; that makes me feel better than doing a wire transfer.
According to Jamie (my contact), there is a 15 day lead time and it will take 3-4 days to ship via DHL.
I will let you all know when it comes in. I hope to buy a Kelly controller this week as well.
Now, if I could just get the donor car sorted out...

31.8 Nm or 23.5 ft-lbs out of a 105 lb motor?? That sounds really bad, am I missing something?

I take it no one else was able to find anything.
Well, heres what I was able to find. I think this is the company that is supplying most of the motors shown earlier in the thread:
http://www.tsxdl.cn/eindex.asp
They are mostly industrial motors, but the water cooled motors are easily among the best I have ever seen for power/weight and size ratio. Only problem is then are all intended for 320V. I'm kicking myself for going with 144v but I had no way of knowing these motors even existed when I ordered the battery. but such is life.....check out the efficiency in particular.
http://www.tsxdl.cn/show.asp?Shop_ID=250
The "super speed" motors are also interesting because of the higher RPM and even higher power to weight ratio. Such a motor should be easily adapted to run a fixed ratio gearbox to allow a simpler powertrain without limiting top speed. Technologic, you might like the smaller ones since you don't need a very powerful motor anyway.
http://www.tsxdl.cn/show.asp?Shop_ID=263
The website has chinese and english versions, but the chinese has more actual data on their motor lines so I linked to those pages for showing the specific motors (google can translate some of it). Once you explore the website in english its not hard to navigate the chinese version to get a better idea of what their product range is like. Whats nice is they show a motor frame and the dimensions, then listed underneath are the different versions that are available within that frame. Only thing that is still not quite clear is what the size of their controllers are. Most of the motors seem to be rare earth, possibly explaining the small size relative to power and weight.
While chatting with a sales rep through alibaba, she explained that custom motor design might be possible so I'm going to ask about having a water cooled motor set up for 144V. Fingers crossed.
