dmethvin Posted February 5, 2016 Share Posted February 5, 2016 You can buy replacement motors from places like Ali Express, but I am not sure how you would determine if it is a good match for the X8. Maybe you could contact them? Here is an example: http://www.aliexpress.com/item/The-new-AMA-mute-brushless-motor-wheelbarrow-self-balancing-vehicle-space-14-inch-unicycle-wheel-motor/32569054589.html Are you sure you need to replace the motor, and not some other part?

However the motor is a very simple machine, the magnets won't fail unless overheated, the bearings could probably be replaced separately and ought to be a standard off the shelf size ( in any case they are in the wheel shell not the motor) and all that is left is the copper windings, which would only be likely to fail if overheated enough to melt the insulation - worst case they could possibly be rewound. A fault is far more likely to be in the control electronics unless you know you have done physical damage to the motor. Link to comment Share on other sites More sharing options...
coker Posted February 6, 2016 Author Share Posted February 6, 2016 My first thought was bearings as the noise is roaring gritty sound,not smooth and quiet.Performance still feels about the same. Is there some link I can view on how to replace bearings. Link to comment Share on other sites More sharing options...
Tomek Posted February 6, 2016 Share Posted February 6, 2016 i would replace the whole set of the hub and controlller. the best seller for those is probably microworks http://m.alibaba.com/product/60234663860/2015-New-Products-500w-brushless-motor.html by this you can also upgrade the speed and power of your wheel. no certainty the motor's width will fit your shell though Link to comment Share on other sites More sharing options...

Is there some link I can view on how to replace bearings. @Cloud has totally dismantled the KingSong 14C. Taking the casing apart won't be relevant to the Airwheel but the wheel and hub will be very similar. Take a look at page 3 onwards of the post below:The bearings are in the wok shaped black hub covers and can be clearly seen in one of the pictures on page 3. A hub puller or some heat and a wooden drift may be needed to get the old bearings out. Please note also the very small clearance between the stator (bit with the copper windings) and the magnets ( mounted all around the inside of the wheel rim) This is probably more likely to be where grinding is than the bearings. Grinding would be caused by grit between stator/magnets or movement closing the clearance so they touch. It would also occur if a magnet became loose. Note also in the post that cloud had difficulties reassembling the hub so it turned freely. Care is needed to keep that very small clearance even all round.

If it is still making noise you should be able to localize it and determine whether it is the hub bearings or the stator. If it is not making noise then it was probably the tire rubbing against the shell, which people have reported several times on different models.

Ouch, very good point @dmethvin, I'm kicking myself for forgetting the obvious, especially as I often ride on bridlepaths and when my wheel starts making such a noise I know it is mud/sand in the casing and it goes when I clean it out. Usually I can do it without dismantling the wheel by using a long damp cloth fed over the top of the tyre by turning the wheel by hand until it appears at the other side and then pulling it through covered in mud. It needs to be long enough that you don't lose it inside the casing. Link to comment Share on other sites More sharing options...

marlenewiley Posted April 30, 2016 Share Posted April 30, 2016 You can buy replacement motors from a reputed dealer near your locality. You should replace the whole set of the hub and controller. Link to comment Share on other sites More sharing options...
