Full controller set is too expensive I think It's better use trans serise 's controller Is remy's motor is BLDC? oh If so that is problem controller is too expensive...
But I know a guy in Korea he can help me..
Me too I just dreamming now..
Do you know that motor is BLDC? ( brushless motor)
Yes, the remy is BLDC.... it's actually IPM (Internal permanent magnet)... but that is because it has a steel band that goes around the magnets in the rotor to keep them in place.
It says the rotor types are configurable. Three of them can be AC IM type. As far as the permanent magnet type goes, I am not sure if it is BLDC or PM AC type..
It was interesting that this was pointed out as Vaxosystems offer only the PM type. EvDrive.com does not say what is the type of the systems offered. But looking at the costs it might be the PM type..
While the PM is slightly more efficient, the AC IM stands out in cost, ruggedness and environmental friendliness(does not use rare-earth PMs).
It would be interesting to know what the cost of a Remy250 AC type motor would cost..
This is a complete Remy250 PM type motor and controller AND a single reduction ratio gearbox AND differential - (according to the site: The D1 is slated for delivery in Q2 of 2011, for under $8999. Additional models, including a high performance version, are currently under development!).
Great! But my initial mail asking for a AC IM type instead of PM typeto them went un-responded..

That's very low power. As for the gearbox, just plug the motor straight into a differential. Same effect. If you have enough torque, you could even use an LSD.
The scott drive is a 150kw peak for $3k, and there is a 100kw peak motor to $2.5k with it in a package....
Wow ! Very interesting!
Combine this red box with this:
If Lotus markets it's range extenders for a good price. Than we can easily convert our cars to series Hybrids. (sorry for the big picture. Use Ctrl+ and CTRL- to get the text normal on your screen. If you wnat to get back to normal view us Ctrl 0)
Hmm. Not as easy as you think. For some weeks I was looking into E-REV design. To make one, we need a bidirectional DC-DC converter so that power can flow into and out of the traction battery pack. Something like this: http://www.brusa.biz/index.php?id=142&L=1
An energy management unit is also needed with a strategy to optimally maintain the SoC
The Lotus solution is interesting, yet that is still not an optimal solution. The ICE is still too large and inefficient. Check out page 10 of this report:
Now this is what is needed as a range extender! I just wonder what will be its efficiency if run on a Miller cycle.. And it can easily extend the range of a car weighing 1245 kgs!
We use an HVH250 in a motorcycle project. Way to heavy and big for a motorcycle, but it would be perfect for a car. It is very reliable and delivers the power. We only have only used 110HP from it with our controller and didnt see higher than 45degC at 300Arms. We may be looking at selling our very lightly used Remy motor later this year.
Nice info! That could be one hell of a motorbike! Any link to your project ? Do you mean 11hp or 110hp ?? Also was your motor AC or PM type ? Which controller did you use ? Where did you buy it the motor..? A lot of Qns )
I've participated in several racer projects which use it. Perhaps at the deep end of the DIY pool You have to be serious, meaning money and engineering talent.
Their website says that it'll be available in 2012... but that's obviously come and gone. I e-mailed them last night to enquire as to availability, and await their reply... still like the Remy though
