Gotway MSuper3 - Axle Problem?

I hope Gotway starts using those anti-spark connectors like in this photo from @Chronic.  I still don't believe we have a definitive reason why sometimes the battery connector explodes upon reconnection.  @Rehab1 and TremF both have experienced the pop of doom.

That would be an improvement.  I used an anti-spark XL90 on my ACM. I never had a another spark (explosion) since. They are a bit larger than the standard XL60 but the side panel closed just fine.

I would be tempted to take you up on that bet. I think it was Jason that told me that the Chinese are vary insular when it comes to EUCs - they don't much pay attention to what the others are doing.

I wish that wasn't the case and certainly wished that they visited our Forum :(

The Chinese are pros when it comes to reverse engineering and copying ideas. Maybe it is different when it comes to EUCs. I bet Boeing has been hit a few times. ;)

I'm just relaying what Jason told me from his first-hand experience with Gotway and KingSong. I have no other insight.

Maybe the Chinese do take a peek under each other's covers, but they do not want to admit it to save face and accusations of copying each other?   I think some might be quite proud of their own achievements and ability to compete against others.

 Why do you think Gotway outdoes everyone in terms of range and speed?  It's that competitive spirit.  I do wish they would also focus on outdoing others on safety and quality too.  Imagine if Gotway had King Song / InMotion / Ninebot shell and control board design levels of quality, safety, and ergonomics.  They would be King.

Other companies like Mercedes (Daimler) seem pretty unabashed with renting cars to tear them apart for research.

I think we're used to companies doing it, but maybe in this case because the  owners are within a small community they don't openly admit to doing so?  Just speculation, of course.  :whistling:

Yes could definitely be some deformation if it’s been ridden while loose . Last I checked Ewheels and green and fashion were the only 2 places I could find that had shims for sale . Being on Brazil I guess he’d have to see which company would be easiest to ship. @Fabris you mentioned you bought the wheel from Chen at green and fashion . Definitely contact him , he seems like a pretty solid guy so I’d bet he will send you some if they do need to be replaced . 

Hi guys, today I dissasembled my wheel , and I saw this. What do you suggest me, please?

Well, your problem was definitely worn out axle shims. These look totally destroyed. You need to put in new ones and then you should be good!

Only problem is getting these. As mentioned in this thread already, you can get them from ewheels.com and on Aliexpress. Maybe someone has some tips where to best buy new axle shims?

@Jason McNeil or Aliexpress (green and fashion) only 2 resellers I have found that have them . Depends on his physical location as to which option would be best from a shipping standpoint .

His best bet is AliExpress. They are kind of like gold in the United States, so I suspect Jason saves them for his customers.

Good call, I've put the request in for XT90S in the next production batch.

I believe the insular theory may be debunked.  Wonder where Gotway got their threaded metal insert idea for the new MSuper V3 1900?

Could it be Ninebot and their new Z models?

Don't be ridiculous... It was obviously the result of @Hunka Hunka Burning Love's guidance / prediction!

:w00t2:  <high fives all around!>. Yeah yeah it's all me!!!  Just wait and soon you'll see anti-spark battery connectors standard on all Gotways.  :whistling:  I deserve some sort of reward, accolade, peer recognition, sexual favor, or something like that!  :innocent1:

Hey...what about me? I may have had a hand in their decision to switch connectors. ;)

Okay okay fine.  :rolleyes:  I don't mind sharing some of the glory, lime light and any potential sexual favors (female wheel groupies where are you all hiding? :dribble:) with my buddy, Rehab1 and that Scott "I'm too lucky" Henley guy (plus TremF!).  When they write the Gotway historical development Wiki and someone reads it 50 years later  - I hope to see us mentioned under "connector improvement innovators / inspirers!"

Whoa this is a family forum Rehab1!  :innocent1:  Stories like that are only to be shared after a few drinks with @The Fat Unicyclist at the local "Tilted Kilt. " :efef927839:  But yes, the  doctor and the second opinion doctor told me my prostate is A-OK if that's what you were wondering about.  :whistling:

The hard-to-turn wheel means that one or more motor wires are shorted together. In nearly all cases this also means that a MOSFET has burned. This will be confirmed when you open the wheel and see the damage on the control board. You will need a new control board.

What does mean this beep sequence?

That diagnostic beep means that a hall sensor in the motor has failed. This means that you will have to buy a new motor too :(

This is exactly what happened to me with one of my ACMs.  Under heavy hill climbing the motor wire insulation melted and shorted the wires together, destroying the control board. Since the Hall Sensor wires  are also next to the motor wires, the insulation melted on the Hall Sensor wire and sent high voltage in the motor sensors.

When you open the wheel you'll eventual find were the Hall Sensor wire has melted into one of the motor wires.

Unfortunately this is an expensive and major repair :crying:

Based on the side panel being loose like that it looks like you took quite a tumble! Hope you're all right?!

This is the first time I've seen a motor lock up quite like this Marty.  It seems like when @Fabris is turning the wheel by hand it's able to freely spin for several inches before suddenly locking up, which makes me think that it's something a little different. If it were shorted motor wires, wouldn't it be hard-to-turn and/or jerky from almost any angle? I don't have any personal experience with a broken axle, but that's what it seems like to me... The only other thing I can think of is that something extremely large is stuck up in the case or protruding from it into the spokes of the wheel, which might explain the large range of motion... 

I don't know... I'm new here and defer to your wisdom, but that's my two cents on the matter.

Good comment @Arbolest:thumbup:

Didn't watch the videos at first as Marty has already answered, but this looks like a mechanical motor problem. Probably the axle broke and that destroyed the hall sensor wires going through it. Might explain the symptoms (and your earlier problems).

A locked tire from a short somewhere looks different. The motor is very hard to turn, but it's even, not a sudden blockade at one position.

Open the wheel (right side panel, where the board and motor cable are) and you'll probably see something right away.
