Hi,
I'm seeking help and guidance with an issue I'm having on my ebike setup.
My original problem/symptom was something was limiting my acceleration and motor power. My throttle was wide open (WOT), I would build up speed, then as I arrived around 40Km/h I could feel the motor cutting rapidly on and off. So I though it could be CA's AmpLimit, but no as it was cutting around 33Amps while my AmpLimit is 40Amps, but I also tried with a higher AmpLimit like 50Amps. Still same symptom.
Thinking it could be my controller, I tried reducing or increasing my phase/battery current settings on the controller but to no avail. I still get the symptom.
At this stage I thought about disconnecting the CA, which I did. The problem was gone. My motor was running smoothly. So I seems to be my Cycle Analyst.
At this stage, I start observing a little more the information from the CA to discover that my top speed was +150Km/s each time I end my rides. I do ride fast, but not that fast . I also noticed that the symptom disappear when I twist throttle less than 3/4.
As I check my CA when I ride, I noticed my speed is not right. It sometimes displays spikes values like 90Km/s when in reality I'm at 40Km/h.
So now I know the limiting effect on the motor is the Cycle Analyst that is speed limiting because it's reading some speed values that are above the CA's SpeedLimit setting (set to 99Km/s).
I checked my pole setting in the CA, it's set to 28 as my motor is an GoldenMotor Magic Pie 3 (MP3). To make sure, I counted 28 poles by measuring the ouput of one of the hall sensors on the motor. If i'm correct, the motor has 28 south poles and 28 north poles which hads up to 56 poles.
I also check my hall sensors on the motor. They all sense the wheel turning. I have 4.80V on power pins (Negative and positive.), and measure 5V on each hall sensor output signal wire. I would say that are working fine.
Does anyone have an idea what the problem is? Why do I have inconsistent and spikes in my speed values which causes my cycle analyst to limit the motor?
