So, I've been back and forth with Fany for over a month now, and the problem persists.
Right off the line, there's a pretty huge amount of torque that falls off almost immediately once the scooter is moving. It won't climb past 20 mph. The throttle output is smooth across its range. I even tried a completely different throttle (Hall type) to no avail.
I'm starting to think the controller is damaged. When the scooter is up on stands, I'll give it about half throttle, then I'll place a DC clamp-style ammeter over the individual leads going to the motor. One leg (W) always reads about 1.5A with the motor unloaded. The other two legs (U and V) don't get higher than 0.5A. I would think a healthy controller would be more consistent across the phases, but this test doesn't feel especially valid to me. Is there a better way to check if the controller is damaged?
