Hey,
So i have a prebuilt drivetrain with belt tentioners, and the belt is crimping and causing extreme resistance. Additionally, the pulley hits the wheel and the motor makes a weird sound.
Motor noise and wheel issues https://youtu.be/mJwJ3L_OIbA
Note the grinding is not as audible while the motor is powered, but spinning it by hand almost sounds like there is chalk being ground in the motor.
Can’t hear the noice as i‘m siting in a coffee place but how much space on your hanger left? I mean the nut sitting flush with the shaft?
If no you could place a 2mm thick washer on the shaft. First washer than wheel with pulley than nut.
Is it possible to release the tensioner a bit?
Just to get your belt a bit more lose so that you can place the motor more in the back.
If there is space, you can also push the motor pulley in a bit more, maybe around 1~2mm. It’ll make the belt go in and align better than hitting the flange of your wheel pulley
That’s good to hear. I would also recommend slackening the belts off a little by adjusting the idler pulley if it’s moveable. It will give longer life and less rolling resistance.
As for the motor it sounds like something is rubbing. I would just check that the pulley isn’t rubbing too close to the motor mount or on the motor bolts. If that isn’t the case you may need to open the motor. It’s very simple and should be done anyway every once in a while to give the motor a little clean
About to fix it. Was not so bad, learn a lot about motors right now because of it.
If I manage to repair everything i‘ll write a small guide how to… think i‘m not the first one who managed to do so
I‘ll check the motors and show how to find out if there are shorts in the windings etc.
After will try to repair everything that it looks and work like new. Hopefully
If no i‘ll show how best to order two new 6380 motors from @torqueboards
Alright had a maiden voyage today. I had to take off a motor because the fsesc dosent fit, so for a single pnumatic board how slow will it go considering im a heavy dude? I think i got up to max 9mph with 12s5p 6374 15t. It could also be tire pressure i suppose
I think the motor is set to 60A peak in the vesc settings
The question is to what is your battery max value set.
Maybe it’s set too low that’s why you can’t drive faster.
Which Flipsky esc you have. 4.xx or 6.xx
I think these are higher values? The tires are quite deflated, but i wouldnt expect it to move as slowly as it does even with deflated tires. With no load the board will move quite fast.
no values look good that’s not the reason.
Besides the battery min is very low with -40.
Would set it a bit up like -20/-30.
But it’s not the reason why you drive so slow
