Re: BionX and phase runner and gauge sensor?

1st question: Do you have any idea if it would be possible to use that 350Ohm gauge sensor on the bionX axcle to make a Pedelec conform e-bike with a BionX hub motor and a phase runner? For sure, that was actually one of my main reasons for doing this since it would it would be quite the ultimate B...

Re: Hub motor steady acceleration using Phaserunner?

I have the exact same problem: leafbike 1500w and phaserunner be extremely slow acceleration and no torque. You want to make sure that you have the maximum phase current set to 96 amps, and that you also have your throttle voltages mapped so that at full throttle the PR's output is at 100% as well....

Re: Bafang G3xx series high reduction ratio geared hub motors

@justin_le when you have determined that the 40A phase current limit on the G310 is the limit, was it because 40A created to much heat, or the actual strength of the nylon gears ? That was directly related to the strength of the gears. We had several cases of gears stripping with 50A of phase curre...

Re: Compact Field Oriented Controller, ASI + Grin, limited run

I do wonder, if you already have OTG and you're planning Bluetooth, wouldn't it be possible to use a smartphone app not only for configuration, but also as a dashboard? Yeah, not just possible but also part of the plan :-) However for successful development it's best to focus on one thing at a time...

Re: Definitive Tests on the Heating and Cooling of Hub Motors

An open motor has a great ability to be cooled with a passive or active fan as you guys did. And a motor case with little air shows to transfer heat better to the case. How much heat could be transferred to the case through radiant heating if an ideal black lining were on the magnets and all in the...

Can one program one of ASI's other controllers (such as the BAC2000) with the latest version of the Phaserunner Software Suite? Out of the box, no. But if you already have bacdoor installed then in principle it is possible to update the firmware on your BAC2000 to have the same customized firmware ...

Max amps going from the controller to the motor ("phase amps") should be set according to the most restrictive specification of : - the controller (ex : baserunner is said to be good for 30-35A phase without going into thermal rollback mode) Correct with everything but on this one point there's no ...

Re: Cycle Analyst V3 preview and first beta release

That was my first idea to do it, but unfortunately the Lebowksi's safety feature won't make it finish boot if the throttle in signal is higher than idle throttle. So let's say you calibrated your throttle to 1.5-3.5V and it sees a throttle voltage of 1.6V during boot it will wait until voltage is a...

Re: Cycle Analyst V3 preview and first beta release

I guess it wouldn't be too hard to implement. Just check it speed>x km/h, then add some (pre defined) voltage to the idle throttle voltage. No need to check for Watts used or so, even though that would be convenient. I guess a simple implementation like that would really help. Correct. The risk wit...

Re: GMAC vs MAC and Infineon vs Phaserunner

So far I love it. The drag from the clutchless GMAC isn't bad at all, in spite of the numbers, in a 20" wheel it seems to coast as good or better than my Stromer. I'll probably still mess with the coasting function when the firmware comes out, but I would be perfectly happy as is. We're just now in...

Justin, do you usually refer the winding turns back to the known labeling for the bafang cst, or something else? No, not at all. The winding turns would hopefully be written on the actual motor stator when you open it up, at least that's been the case from what I've usually seen. There is no reason...
