troubleshooting hub motor kit questions
I have a Grubee (Skyhawk) 48V 500 Watt front hub motor kit. It stopped working after a couple of weeks and minimal usage. I couldn’t find any distributors so I purchased a modified controller. This controller is not a ‘direct fit’ but I think I have it connected properly.
If I give it throttle and lift the front wheel it will spin but not smoothly - there is some humming and intermittent loss of power. The motor doesn't have enough power to move the bike even without a rider.
Is it possible to wire the motor directly to the batteries? Is this a good test to determine if the motor is not damaged? If so what wires from the hub motor do I connect directly to the batteries?
Any other suggestions to systematically test and eliminate the throttle, controller and motor?
Might be in the hall sensors.
Check out this site, it may give you your answer:
i'd bet it is the hall sensor wires as well
just try the different wire combo's
and no don't hook it up direct
i believe that only works with brushed dc
