Impressive find

 

are there controllers availble for these motors that would provide regen?

 

Ok now i will go find the controller I will attack it like a pit bull never let go LOL

 

Ok found this site for controllers it said up 500VDC http://www.made-in-china.com/showro...devernature/product-detailseqQzSdGbapL/China-Brushless-Dc-Motor-Controller.html
and anothere site for motors brushless

Wow those seem like great finds...bravo...

Now whos going to fork it out to buy them and test them and share the results with the entire community?

This setup could even be retailed as a kit, similar to the HPG setup...

 

well i am saving some money every week so when i get enough i will be buying i dont know if i will go for it all or just the controller due to i have some motors but there female shafted

 

A BLDC controller will not work on your series DC motors.

 

I have contacted the DC motor makers asking for prices for there 144V 10KW + range. Will post back what i find out.

Untested controllers make me nervous, had a dodgy kelly before using a curtis that had crap acceleration (for a race car) from 0 but good from 10kph +. Im also looking for a 144V 1000A+ model, but if the price is right 500V 600A would do! If anyone buys/gets more info/owns the company please share.

l, but if the price is right 500V 600A would do! If anyone buys/gets more info/owns the company please share.

See above for the details which i received in reply.

DL144-22.0B3 for US$1007 or around ~ AUD$1,500... hmmm

 

Those are sort of small motors, the largest one is 74 nm, or 54 ft lbs of torque, RPM of 3600, with a price of $3600 for motor and controller. The HPG AC systems get you 100 ft lbs of torque, 6500 RPM, for $4200 for motor and controller, and you don't have to ship them from China.

 

it looks like 2500 for motor and controller and about 1000 for just a motor i could be reading this wrong but thats what i am getting

 

I'm pretty sure that one table is for the motors and the second is for the controllers, so $1176 for the largest motor plus $2544 for the matching controller equals $3720, not including shipping I'll bet, for a motor that produces 54 ft lbs of torque and 3500 RPM, and weighs 224 lbs. That makes it twice as heavy as a HPG motor with about half the torque and half the RPM. Not a great deal from what I can see.

 

In the 2nd PDF if you look at the DL 35-3200/320 puts out high torque and is about 140 lbs

 

That's much better, but I don't see prices. Comparing to the DL144 prices I'll bet the DL 35 will be much higher since the output is so much higher.

 

ya it might be but you never know but i think it will be higher but just how much if it was $600 higher that still wouldnt be to bad

 

Considering it's almost 3 times the output at two thirds the weight that would be an amazing price.

 

hmmm i have tried to contact the company with email but no luck i want to know how much for the bigger motors 35KW and up

 

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.

 

Ftaffy tried for more info but they never sent it I welcome you to try pleas post any info thanks

 

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.

 

looks like this could be a great find! Definatlely post back if you decide to use them and give a review.

 

I sure hope you get info i am saving my money

 

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.
