I have an enertion single drive mechanical kit that I had lying around for more than 2 years now and I finally decided to use it again. It had one problem, the belt skips when accelerating/braking to hard, tried to fix that today but nop, it still is the case !
I have the 16T pulley on the motor shaft, it is a Turnigy Aerodrive SK3 - 6374-192KV .
I have a Flipsky Dual FSESC4.20 100A but I’m only using one motor, and a 6S 20C 5Ah lipo battery for the moment.
Whenever the belt skip, it does it only one time and then it stops accelerating/braking (it cuts the power), I then have to center the triger and accelerate/brake again, and still if I push it too hard it slips.
I don’t know why the power cuts like that, I think it’s from the VESC but what ? Two years ago when I used a hobby ESC it just kept slipping like crazy if I didn’t release the trigger.
I even tried to tension the belt way more than you are supposed to but it still skip !
The last pic is a video where the motor is blocked and I apply as much torque as I can on the wheel with my hands, results : the belt skips even by hand (note that I have to put everything I had to do it, but it does skip !)
So if it is slipping with my hands, I don’t know how it’s supposed to hold up to a 4000W motor (even though I don’t use more than 1600W because of my configuration).
So is there a problem somewhere or is it just that the kit is bad ? I mean yes there are not a lot of teeths in contact with the belt (on the motor shaft) but If enertion sell such a configuration, it’s supposed to be hold the torque right ?
Thank you so much for your help,
Please check the imgur the video is at the very last
It’s hard to see but when the camera shake it skipped.
Yes it’s a HTD265-5M, I understand the motor pulley size and tooth profiles but I really don’t get why would belt size be a problem ?
Stop throwing % around lol. 15mm will handle the torque better than 12mm. Going dual would make it handle the torque even better.
Diagnosis:
I do believe your problem is going to be running a single 12mm belt.
Solution:
Uprade to a 15mm setup, have a beer/soda and call me in the morning.
I wouldnt say you bought the wrong thing or even that enertion sold you “shit”. 12mm is fine if youre running a dual setup. But on a single 6374, its a little under par.
Well I don’t see why the increase in torque wouldn’t be linear. 15/12*100=125% So if it really is 25% I mean yes it’s better but still…
By the way, if I tweak the settings of the VESC well, I manage to get a configuration where It doesn’t slip but I was looking for something more “zippy”
My order was a " MONO DRIVE MECH KIT", everything was included, I didn’t buy parts here and there so if it is sold as a mono drive kit it should be able to hold the torque
What they wont tell you is, on a single 12mm wide setup, its not par for a single 6374. 12mm is good for running dual. Sinle 15mm will work better. Single 20mm will work great. Follow?
I tightened it like crazy once but it was still slipping. About shortening the belt, can you please explain me how it’s going to affect the slipping issue ? I really don’t get it From what I understand if I use a shorter belt the axles will be closer and it’s going to engage less teeths on the motor ?
Oh I meant either moving the motor or shortening the belt if you can’t, if you’ve done that and it’s still slipping I don’t know really… it’s all pretty simple mechanics.
