Motor temps - right vs left

I'd like to see what data others have with theirs.... But I'm finding my left motor runs quite a bit hotter than the left. This is with all the cooling holes exposed on the motor and running the board with 83mm street wheels for a mile or more. I'll need to get my IR temp gun and see what numbers I get, really want the internal value but I'll see if I can shoot inside the cooling hole.

Anyways, I emailed Evolve and mentioned it on the side, they said I should email service about it and see what they say. Sounds good. But I really want to get more data from my board to them before using up their time. Board rides great, but just an observation I'm curious about.

Some thoughts.... The remote shows the RPM of each motor on one of the menu secret screens. I'll need to grab that data and see if the left is running faster/slower than the right as well as how many amps its pulling both on average and peak. The other variable would be belt tension, I notice that depending on how tight/loose the belt is that's a factor on which motor spins up / slows down before the opposing one. That also can build up heat if you're comparing two motors with different tensions.

As always, the board is wicked and still stoked I own it. It carves like no other board I've been on, really love that awesome freedom and connection like your surfing and snowboarding.

 

it shouldn't think it would be an issue, even after a long ride i find the motors are still pretty cool enough to touch them, compared to the older gen 2 boards with the single large motor, those things run a little hot. As long as the wheels spin and stop at the same time they should wear the same. Post your temps or screen caps though, the more info that is out there the better for all of us.

 

Yep, will do. Was on my way to do that experimentation with taping the cooling holes but found that one motor to be running a tad hotter, so I ditched that idea for now until I can understand why that one motor is hotter.

 

I've done a fair amount of hill climbing on my Carbon GT along with a friend who has the same board and we both noticed exactly the same thing on both boards. That said, it wasn't hot to the point where I was at all concerned, but it is an interesting observation. I cant fathom why, but one motor MUST be working harder than the other for some reason.

 

Ok, thanks Jimmy. That's a good data-point. I'll post my observations as I get time to experiment with different user variables to see if they have any effect. I may email Evolve service as well just to see their view on it technically, possibly they already have an answer like what I discussed about the different belt tensions. I'm going to use a guitar tuner and pluck the belt (to get them close to being the same tension), the next time I adjust.

 

Hi wiztecy, how does one access this secret menu screen?

 

Thanks!

 

I have the carbon gt and my motors have different temp when I'm using the board for a while , even if I remove all the parts and run the motors bare without wheels and belts, always the left motor gets warmer than the right motor. I checked the rpm and they are the same and the amperage they draw is the same but the left always gets warmer than the right , I double checked that with an electronic Rc thermometer and it is around from 5 degree Celsius to 14 degree when I push it some more and stress them .
Although the temps aren't so high but the difference is quite high like 30 the one and 44 the other ... any thoughts ?
In case that someone ask ... I have told the evolve HQ AND THEY SAY that this is normal but my opinion is that something is different inside these motors ... maybe the winding ....

 

It would be an interesting if you swapped the motors and did a test then. And by swap I mean make the right motor the left and the left motor the right.

 

Yes but all my thoughts is that it would be again just the same difference ... much possible that the winding inside the motor is different then the other thinking of more resistant so that's the reason it gets warmer than the other .....

 

I already did that only for the outer motor not the one inside the winding .. but the same ....

 

As I said before I did the test without any belt or wheels on .. just bare motors ... so no external stress were applied ...

 

Sometimes I feel the way people come off they don't appreciate others input or help... Give him some slack!

 

No prob we all just try to figure it out .. thanks for your help though

 

As I've been told from evolve HQ that this is normal to have diffident temps one from the other motor and if I want to fix this then I have to send my board to them so they will test some motors and find 2 that emit the same temperature .. and if I want a replacement for the one that gets warmer , then they told me that the new one may be even hotter than the one I already have or ( I suppose) less warmer than the cooler one I already have ...
