Re: Lebowski controller IC 2.B0 source code and (short) explanation
I also spent a lot of time setting the gap and making sure the RLS chip was centered.

Re: Lebowski controller IC 2.B0 source code and (short) explanation

Both inverter and motor are connected to each other and car chassis via 6mm2 ground straps. I thought that would be enough... tnx Arber I hope you meen the inverter enclosure and not the tr...

Re: Lebowski controller IC 2.B0 source code and (short) explanation
So what did you use to get better response? Did you just lower winding resistance and add more phase torque? Or did you advance RLS encoder signal? By how much? I tried up to 35deg and there wasnt any improvement. Do i have to use real degrees? That would be 4x35deg = 140deg electrical? Now everyth...

About 25 lbs more then a factory 450. I need to weigh it once the 3d printed parts are on it.

Re: Lebowski controller IC 2.B0 source code and (short) explanation
Hi Lebowski I still consider starting torque with my motor rather lame. I have read on the characteristics of IPM motors. As you may know Leaf motor is 8 pole IPM motor. I wanted to ask you if you considered IPM motors with your software? Here there are two torque components. One reactive and one r...

Re: how to program a sevcon gen4
Hey. Anyone willing to share a ME1616 / 1507 (or other ipmsm) dcf for gen4? I found some interesting info in the dict and wondering if there's an id lookup table enabled for these ipm motors. I'm trying to figure out how it's set up: I tried the Speed dependent FW and so far it has not made any dif...

Electric 450 CRF conversion.
I have not spent as much time on ES as I used to. I have been busy with many things. One of them has been this bike. About 2 years ago I picked up a 2005 CRF 450 with a rod sticking out of the cases. From there I started figuring out how I was going to make a fast and fun to ride Electric MX. I 3d p...

But at the end of the day this is a top notch product! If the average enthusiast cannot justify the cost then what is the chance that when I come to buy one they are no longer available due to lower than expected sales? We don't have an expectation for sales numbers. We will grow this organically. ...

Re: Axiom: a 100kW+ motor controller
Out of interest, what are people expecting these to cost when ready? Well you can start with the cost of the parts and its going to be more then that. We are not talking about selling a kit or a control board. If I were to buy the two I need at the price suggested then it will cost over NZ$22,500 o...
