I followed the chart diagram posted here in ES (ES wiki probably). It was a 1st time for me, so it's hard to comment. Around 10-12th time was the hit
With 3kW motors, there's inherent flaw/quirk: hall sensors will pick up a "stray" magnetic flux between magnets. It initially made my motor to "run away" - applying full throttle and releasing it meant that RPM still remained near max range. It's not something you'd want to happen while riding. Trapezoidial controllers (including stock one) are immune to this. That's why AFAIK Cyclone 3k hasn't been paired with Phaserunner or others sine controllers very successfully.
Spent a lot of time debugging and searching for a cause.
There was a YT video from a Russian guy (this forum/topic
) who disassembled one motor and tried to get it working with a Kelly sine controller. Unfortunately the video is now disabled/unavailable.
In the video, it was solved by replacing halls. I tried to replace originals to SS41's but that didn't help.
In this post there's couple of screenshots: https://endless-sphere.com/forums/viewt ... 6#p1318337
In the end I added extra 560ohm pullup
resistors as a workaround. So far it has been working. Will try to replace halls to SS413A as those seem to be with lower sensitivity than SS41's.
