Hi All,
I am an e-bike enthusiast with some limited troubleshooting experience, in need of advice from the community here. I have a phaserunner, 52V battery, and ezee 350 rpm front hub motor. I have both a throttle and Sempu torque sensor connected on the bike. I mostly have used the torque PAS mode on the CA3 to control the motor.
When I go through the Phaserunner autotune process, during the motor spin test, I get the error:
No current detected on Yellow phase. Please check the motor connection and try again.
I have checked the integrity of the phase wiring in the motor by shorting each combo of 2 phase wires and turning the motor - it spins freely without shorting, but I feel resistance turning the motor when any 2 phase wires are connected, so I assume this means the phase wires within the motor are not shorted together and the phase wires are intact. I did the same thing at the end of the wire connecting the motor to the controller so I assume there is no issue with the wire from the controller to the motor or the connectors on either the motor or wire. Does this error mean there is something wrong with the controller? I tried spreading the male ends of the phase connectors on the phaserunner to get a better connection, but that didn't help. I am looking for advice as to how to further troubleshoot, or any ideas about what is causing this error and how to resolve it. I am thinking of ordering one of the Chinese ebike testers to test the phase wire outputs from the phaserunner - I sort of doubt that there was an issue with the phaserunner from day 1 and there is no sign of any damage to it, but not sure how else to troubleshoot the issue.
I have been able to use the motor in sensorless mode (recently replaced and verified the hall sensors are working, still need to replace the JST connector for the halls between controller and motor that got damaged in the process to connect the new motor halls to the controller), but I don't think I am getting the best performance. In particular, when the motor starts after having stopped (e.g. when coasting and pedals not moving so PAS cuts out, then start pedaling again and the motor starts again), the controller throws a lot of power into the motor for a few seconds and causes the bike to accelerate, even with minimal pedal force. This only happens when the motor starts up again, not if I am pedaling at a constant rate. I am guessing this is part of the sensorless start-up operation...I'm not sure I have really used the halls sensor start-up or not with this set-up because I think I have always gotten this error during the autotune process and I have limited experience with this. When I look at the amps going into the motor on the CA3, it is way more than the sensorless start-up injection current, so I'm not sure what is going on each time the motor starts up after a stop or how to make that more gentle. I am playing with the sensorless start up settings but so far haven't found parameters that fix that issue.
I verified that the #pole pairs and kV are correct for the motor I have within the phaserunner configuration. I think I have been getting the yellow phase error since I got the phaserunner a year or 2 ago and have been using it this way, but now digging in to it and wanting to resolve whatever the problem is. Any advice or suggestions are appreciated!
