My e-bike setup: GMAC10T, 52v30Ah EM3ev battery, Phaserunner, CA3, Grin Standard Throttle, Grin PAS24p Pedal sensor.
See back story below for reason for the swap out.
GMAC10T out Bafang G310STD in.
Swapped setup is:
Bafang G310STD, 52v30Ah EM3ev battery, New Phaserunner, CA3, Grin Standard Throttle, Grin PAS24p Pedal sensor.
I swapped in a Bafang G310STD and a New Phaserunner.
I imported the Bafang Settings from Grin, and AutoTuned the New Phaserunner with the G310STD attached.
Everything appeared to be fine on a test ride.
26 km round trip ride for Work.
About 3-4 km into the ride I had to stop at a traffic light.
When I started up using the PAS24P only, I could hear a strange motor noise and had no power.
The noise continued as I pedaled out of the intersection.
I stopped the bike again and powered the battery off.
Waited 15 seconds and powered up.
I was able to use the Throttle and PAS to get going.
I rarely use the throttle and so almost always am using the PAS.
In the next 2-3 km I had to stop pedaling but no brakes and coasted for about 15-20 seconds.
When I went to resume pedaling I once again got the same motor noise and no power.
I tried the throttle but nothing.
The motor noise sounds like the motor is fighting braking and forward motion.
This issue continued all through my ride no matter what my speed, if I stopped pedaling.
As soon as I started to pedal again I would get the motor fighting noise.
The only way I found to clear the issue would be to fully stop the bike for 3-5 seconds.
I left the battery turned on while stopped.
If I applied a little Throttle I could feel the motor power up.
I could then Pedal away and continue with lots of power with no issues until I stopped pedaling.
I tried braking, I tried moving to not power assist to 0 before I stopped pedaling and nothing helps.
Looking for anyone that may know what is going on.
Back story on why I am running my spare Wheel and Motor:
+++++++++++++++++++++++++++++++++++++++++++++++++++++
I think my Phaserunner has got a nasty issue, it was causing the GMAC to act like it was e-braking and trying to drive forward.
I was getting Phase Over Current whether using Throttle or PAS or both.
I swapped out the Phaserunner, downloaded GMAC setup from Grin, I ran AutoTune and that appeared to correct the issue.
I put everything back on the bike and ran the motor un-weighted.
I swapped the original Phaserunner back in and uploaded the same setup from the new Phaserunner
(I had the same original issues of the motor appearing to fight e-braking and throttling forward and shutting down the Phaserunner with Phase Over Current.)
I swapped the New Phaserunner back in.
The motor ran and New Phaserunner appears to work ok.
I did notice there was a noise that sounded like one of the motor bearings was failing.
I took everything of the bike, stripped the motor down so I could test the bearing with my fingers.
The bearing is pretty crunchy so I did not want to ride it.
Need to find the correct bearings for the GMAC so until I can figure that out I had to Swap to my spare wheel and motor.
