Controller for sensored C80110 80kv

[eastbay]

Hi Guys,

I plan on building a pair of 3-wheeled karts with our kids. They should be relatively light and quick but not crazy fast. We figured that the Alien sensored C80110 80kv would fit the bill pretty well. I spent several nights reading here (amazing treasure chest!), but I'm still not sure about the optimal controller. I'm looking for something that runs these motors reliably without much modifications since I must admit that I'm more into mechanics than electronics

We plan on getting about 2 kw (~35A) average from the motors on 60v with peaks of around 4kw (~70A). The Kelly KEB72301X (Peak 150A, Continuous 60A) looked good to me. Is that the best choice, or should we better go with a different Kelly or a Lyen, Infinion, Alien, something else...?

Thank you guys!

http://em3ev.com/store/index.php?route=product/product&path=38&product_id=81 this controller will do the job .

I would run the motors on 48v rather than 60v , but if you need to run them on 60v then I would go for this controller http://em3ev.com/store/index.php?route=product/product&path=38&product_id=82

Also dont rule out the 6374 motors for these sort of powers .. but it will mean fitting extrnal sensors.

its a shame that alien dont do the 8085 :?

Aren't those Infinions a bit small? On 48v the 40A max would get us to less than 2kw peak, not really the 4kw we're shooting for.

12fet controller fitted with 3077 fets , then reprogram to 89-100A

If doing that one should also beef up the rail lines, caps and so on. also thicker wires.

they are already done if you buy from em3v

Is there an advantage of the Infinion's in comparison to the Kelly's?
