IMO, 10,000 KM is good enough for a motor also for my purposes. But as I said, it only took 1/5th of that to start noticing the issues this thread is all about. I know I won’t get to 10,000 KM with these motors due to the fact they are slide fit and not press fit. The fit when they where new was very tight, so tight that it was hard to get the bearings on. When I take the motors apart now, they have a hair size of play. Not an insane amount, but enough that I bet 1 more year of use like this is all they will last. That’s less than 5000 km of use.
Design of the motor will obviously have an effect on the rate of decay. But without pressed fit bearings, you can’t escape this decaying… It will happen. Really, vibrations will do this, no matter the design of the motor.
@onloop I will tip my hat to your work, You seem to have spent more time researching hub motors than I give you credit for. The thing is, it goes back to what hummie said, about whether this is a marketing platform or an informational forum. In all manners of R & D besides these motors, you make sure the world sees all of the work you’ve put into R & D. 2 years back when I got my first pairs of carvons, you said you didn’t understand how a 149kv hub motor could even work with the vesc, and the impression your remarks about my use of them seemed to imply you didn’t see a future in hub motors (especially because you followed up by saying something about satellite config motors being better). I knew of your work with Jacob in his motor quest, but I guess I assumed you stopped that after his work fell apart, since you seemed determined to stick with the satellite config biased on the comments you had made and what you were promoting publicly. I never saw you saw one good thing about hub motors up until recently, and you always said satellite was better. I’m sorry if I offended you by accusing you of not having much experience with hubs.
However, these last iteration of your hub motors seem to be the first real modify you’ve done to the motors, since the videos you posted in the past while you where waiting for your prototypes where Jacobs old motors. With the mods you made from the old design to this new design, it has only been a few months of testing, which I think is still too short of a test a modified design. Changing one little thing in a motor can drastically change the way the motors wear and tear. And it seems like you changed quite a bit from the old motors. I just don’t see how you can test for such a short of a time and feel confident that nothing will go wrong in the long term, even if this was your 10th iteration. The fact that most of this board was sold with CAD drawings and shipped 6 months later speaks that there will be limited real world testing. You do you, but like I’ve said before, I want you to be successful. I’m looking at a different customer base. In order to ride the boards I’m making, you will need experience riding a weaker board, but still very powerful board, such as the raptor 2. I’m not trying to brag, this is why I hate text like this. You can’t tell my actual emotions behind what I’m saying. Your success is paramount to any success I could have. It builds the industry, and builds a potential customer base for me, when people want even more. So everything I’ve said, is not from a point of jealously like you think it is. I’m thinking the bigger picture here. It’s not about bashing your product. It’s about offering my opinions of areas of improvement, based on all of the experience I’ve had testing many different hub motors over the past 2 years and different battery technologies, so it can help grow the industry. We both want the same outcome for the community, so why do we have to fight about it? I don’t want to fight. But I can’t even mention a potential flaw with out being accused of having an alternative motive.
