My brush motor started making a whirring sound after I ran it pretty hot this morning up a steep hill, so I am guessing the brushes are needing replacement, does anyone know where to get these motors serviced? Or does it sound like some other problem? It was quite sudden one moment it was running fine just the normal whine, then something gave way in there and an unwelcome new noise joined the party. I am going to try LEVT for starters.
Its a 24v rated heinzmann brush hub motor on one of the evg e-bikes. Haven't got the $ for a new motor so figure I got to get it repaired which I read on some of the threads does not have to be that big a deal.
Thanks in advance for anyone who can point me in the right direction or shed more light on my lamentable situation. the motor still runs but I don't think I want to use it and make things worse.
