Hi All,
I've been happily ripping around on my bike w' a Phaserunner & Grin All-Axle front hub motor for a couple years. I recently bought a Baserunner because I like the cleaner install. However I'm not getting as smooth a ride as I did w' the Phaserunner so I'd like some help figuring it out.
With the Baserunner I'm noticing:
1) A high-frequency vibration from about 18km's/h through to 28km's/h when accelerating. Above ~28km's/h the vibration stops. It is very mild but I don't remember feeling it w' the Phaserunner. Seems greater when using throttle but also happens when I have assist set to 250W and I'm just pedalling w' PAS.
2) On my commute home yesterday I started feeling a 'knocking' from the motor. I thought it might be mechanical but it stops when I stop pedaling or don't use the throttle. It seems to be at about the same frequency as the wheel is rotating. I hooked up the diagnostic software last night and all three hall sensors are working. The knock is fairly inconsistent - it is happening about 50/60% of the time but varies in intensity from barely noticeable to quite noticeable.
3) Really inconsistent regenerative braking performance. It turns on and off (even with the CA indicating the brake is activated) and 'studders' a lot during braking.
I messaged Grin and Justin said : "we've also had a few cases of motor vibration that went away when the motors winding resistance value in the Software suite was manually reduced by 10-15% lower than what was provided in the autotune routine, so it would be worth trying that out too."
So I lowered the Resistant value from 74.00 mOhms (autotune) to 62.00 mOhms and that helped with vibration. Still some 'knocking' during acceleration and lots of 'knocking' during braking.
Anyone else have this setup and can tell me what parameters you're using and how the performance is?
