Hi Guys,
i have the BMC geared hub motor i have purchase from ebikessf.com
i have purchased it as used motor.
from the begining i recived it it didnt run properly.
i had to replace the one of the hall sensors.
now i runing it on a 16 inch spoke wheel with 9 fets infenion controller (sensores)
at 36V it runing badly, its not runing smothly at all and its runing in pulses- the pulses not start at the begining , at the begining its runing smothly and a\when i go to about 8 mp/h, its starting to run in pulses very anoying .
at 48V its happens only after about - 1.2 miles, till tis distance it runing smoothly, but after this distance it getting even worse, it can start alone, it need push, and its starts pulse again and cant gain speed above 8 mp/h.
anyways it seems like the top speed is to low the max speed is about 12 mp/h.
what i have checked:
1. i have tested the pahse wires and hall sensors - both looking good.
2. i have checked for heating, the motor does not heat at all and the controller not heating at all , alsi pahse wires not heating.
3. i have tested the throttle- seems ok.
im hopeless, this motor drive me crazy, anyone can advise?
many thanks in advanced
