Hi all;
So I got a new 48v, 1000w hub motor and controller from BMSBattery. Assembled on the bike and blipped the throttle, but it only spun up smoothly about a third of the time. The rest of the time it's just stone dead. It's then I noticed that the motor/halls wires from the hub were pinched at one point, so I cut them short and re-wired the plugs on. Again, it was able to spin up a couple of times but now doesn't do anything. Now for the technical:
Battery puts out 51.5v without anything connected, but then shows 12v with just the controller connected (no motor). The halls sensor/power wires coming out of the controller are 2.5v, when they should be 5v according to the circuit board. The halls sensor wires, without the motor connected, are putting out ~3.5v from the controller (?). Connecting just the 2.5v wires to power the halls and testing the sensors spinning the wheel backwards consistently shows 0v for each sensor.
Inside the motor looks ok, but I can't test the continuity of the wires because there's just too much epoxy holding it all together. Inside the controller looks ok too, but perhaps some of the capacitors could be stuffed from when the motor wires were damaged? Any ideas?
Cheers, Dave.
