Wooohoooo! Thanks for the update sir!
I would need some help.
Just managed to get this motors working, but when I spin them with remote top motor at higher speed starts producing that strange sound, which I think is not right. So any idea how to fix this, I spinned them couple of times but everytime there is this sound. I dont want to spin them anymore so I wont break anything, and by the way motors were never used, just spinned now couple of times.
@NEKDO1 You should be testing with full assembly on meaning wheels included. I wouldn’t test like that. Your motor could potentially fly off. Do that first then test again.
Same sound when wheels are on aswell. So what that means, everythink okay with motors or not?
Someone has DM me and said: “It sounds like the housing is wobbling and scraping the coils. If you continue to use them a wire could break and then you could have a short circuit which would ruin the whole of the electric elements.”
Is that true?
You should be fine. I’d ride it and test it at low speed. If any issues email us.
So today went for a short slow ride (less than 1km). When accelerating motors act normal, but when I brake I can hear hrrr like something is scratching and more time I am holding brake motors are losing brake power.
You’ll have to email us with more info. There’s not enough info to diagnose your issues.
Already emailed.
Went today for a short ride to test skateboard.
When I add a little gas there is a little strange sound coming out of right motor, but if I do gas over half it accelerates normally with okay sound. Same with breaking, if I brake with a little power or full brake or if I brake for a longer time or if I am near stop, there is similar sound as if I add a little gas ti accelerate.
I am new to electric skateboards and this sound is a little strange as if something inside motor was scratching or rubbing to something. I just want to make sure that everything is okay so I can normally ride.
I think it might just be the motor a little loose on the hanger. Just take the motor off and add some kapton tape or electrical tape to the hanger where the motor sits. Then go ahead and slide the motor back on and it should sit without rocking.
Additional comment:
Let us know if this resolves the issue (I’m fairly certain it will)
Yea that motor from where this sound is comming is a little loose, I mean I could take it of by hand.
Today shops are closed so I will try and fix this tomorrow and see if it is better. But thats good that nothing is wrong with the motor :).
Thank you sir for that information
Yea you should be able to just remove the axle nut and slide the entire motor off the hanger. Then just add a little tape on the thick portion of the hanger nearest to the middle. Then slide the motor back on and add the lock nut.
Should only take a couple mins at most.
@NEKDO1 - Yeah, that sound you’re getting is what I call collar chatter.
You can add some thermal paste or thermal tape to the hanger.
@Ahrav You hired… Ahrav to the rescue.
Hey guys. I would need help again.
So I have added that termal tape to the hangar and it is slightly better with noise. From time to time it is gone but then comes back and then goes again.
But I have bigger concern. Brake is still not working as it should be. Here is video of riding down a small hill and testing brake. If I increase brake it is braking, but when I come to full brake there is that Hrrr noise and high pitch noise like something is rubbing and frying inside motor. When I almost stop, I am riding at 2km/h that noise disapears but I am still moving and skateboard isnt braking but I am holding brake at full power. This can be seen on video at the end.
Its like as I said when braking and decreasing speed brake is loosing power and to full stop I need to stop by foot.
This is a huge safety problem to me, like a car which cant be fully stopped with brakes.
So I was told to ride it, and now I cant refund it, I would need help ASAP so I can use it and feel safe on it.
Probably it is something wrong with that motor, or maybe I have set something wrong on VESC.
Thanks for all help.
Post up your vESC settings so people can check what (if anything) is wrong with them.
I have setted motors on BLDC, hall sensored mode, 70A, -70A, 30A, -8A, 12S. I dont know what exactly info to put so here are all settings. For programing I have used VESC tool 2.03
Hope this data helps.
