I've been considering posting it on here for others. Riding your bike on high power must be a lot of fun. The most I've experienced on my bike has been 14kw and that was amazing. In my videos I'm only running about 10kw and even that feels really quick.
Takes a while to find the right balance of phase vs battery amps to make these beasts ridable.
Yep, the 36fet that SteveO built back when the 36fet boards first became available, and I couldn't have done it without your version of the program. Regen is almost too high already on the lowest setting, so further shunt mod was out of the question. The existing shunts put me at Actual-to-Programmed current of just over 2 to 1, so I need to set the battery amps to almost 200 in the program. The highest on the pgm version I had was only 100A, so your version gave me half of my current power.
What's the highest power you've actually seen on your display while riding? With those slower wind motors it takes some real effort to ensure that AMAX isn't just a 0rpm burp on the first rotation. I went on a 15 mile ride yesterday, and it took a few tries on a smooth deserted road to steal a glance at the CA at the right time, but I finally got to see 30kw flash on the screen as the motor crossed thru the peak power point. You skinny guys only need a bit more than 20kw to feel what I do at 30kw, so you might be able to get there, but it's a lot more likely with your 2 turn.
Keep in mind though, that I could feel the difference between 28kw and 30, so the motor has more to give. I stopped at 30kw out of worries about the controller. Maybe 40kw is the real number. I just need backup controllers before attempting any higher.
BTW, I can't wait to get one of the 6 phase high efficiency motors for testing. Apparently the largest is the size of Hubmonster, but with peak efficiency of 94%, and a slot count of just 24 it's going to be capable of much higher rpms. I just hope there's a work-around the factory controller, because it's limited to much lower power. This year is going to bring some cool changes to our hobby, and guys will be able to run real 10kw power without modding their motors. Hopefully controllers and batteries can keep up.
