Re: Serious FOCer (84V VESC 6 based controller)

Excited about all this! I've been very impressed with the capabilities of the VESC but have been waiting on a high voltage version before building my next ebike and the Little FOCer would be just the ticket. Not concerned with enclosure issues personally as I will have my own custom version. All pow...

Re: 2 years after the summer of peanut butter gear Bafangs??

Too bad that BPM is sensorless. I'd scoop one right up, but I'm afraid it will be voltage limited due to electrical rpm limitations of sensorless. :arrow: A custom order of sensored Bafang BPM motors in a range of speeds was made by me last year :wink: Most the motors are in Australia but some are ...

Re: Doc EXTREME 36 FETS controller

A note on Kapton materials: not all Kaptons are the same. Eg 'Dupont Kapton MT' posseses "3x the thermal conductivity and cut-through strength of standard Kapton® HN". http://www2.dupont.com/Kapton/en_US/products/MT/index.html This seems pretty significant as it suggests 3 x 3 = 9x the thermal perf...

Re: Bafang BPM Pics and Specs - Large 3.9Kg Sensorless Geared

Re: e-crazyman controller oddities

The first of these 206s that I modified would cut out when the throttle was applied too suddenly. I discovered that I'd put the wrong value power resister in by mistake (the big grey one standing up near the big capacitor) and was able to correct it and solve the issue. Is this a possible cause in y...

Re: Bafang BPM Pics and Specs - Large 3.9Kg Sensorless Geared

Thanks for the initial review. This motor looks like a nice step up from Bafang's smaller motors - such as the SWXH which I've been enjoying lately, but find it gets too hot easily for my needs. Full-throttle, you mentioned a "top speed of 37 km/h" for your code 13 wind. Is that on level ground with...

Re: Single speed E-BIKE advice

Personally, I would test your system out with rear gears, then remove them if desired. The optimum gearing set up will depend on so many things - riding style, terrain, and the characteristics of the particular motor - that it's hard to know in advance. I think that having a range of gears on the ba...

"Every act of creation is first of all an act of destruction." - Pablo Picasso Great reporting! Regarding the possible cause of the FET failure: The regen conditions don't seem to be much of a candidate: '-10A', <90V I assume. Though rated to 100V, 112V has been reported for the 4110s.
