Motor temps - right vs left

Easy, you have more weight on the side you are standing causing more resistance which in turn requires more motor power for the speed controllers to keep those wheels moving at the sames speeds.

However, if you are able to replicate it with the motors off then my theory is bunk. Didn't read that part.

 

Another easy way to check current in the wires is with an AMP CLAMP METER. If you can isolate the ground wire you will be able to check amperage without disconnecting anything.

 

Today I'm gonna do the swap motors test and check the temps ... then I'll let you know my findings )

 

As for now I checked out this one ... and I noticed that on mine board the readings about the left and the right (M2 and M1 accordingly) motors are different, the amps current and the rpm by a little amount. My thoughts upon the this relative with the different temps are that the M2 which is the left motor draws less power and runs a bit slower but gets warmer than the M1 which draws more power runs faster and its cooler than the M2. It is strange how the one that's draws less power and has lower rpm gets hotter than the other that draws more power has more huger rpm and its cooler ????
Here are some screenshots in various rpm....

 

..... so I swapped the motors ports and the readings got swaped too but with less temps on both motors ...
So without riding the board but with BELTS and AT WHEELS I got after 2 minutes , 31 degrees on the left and 33 on the right motor now .. which is exactly opposed readings as before the motor ports swap (with less higher temps at both becuse of less stress at both )
My thoughts are that the M2 port gives to motor less current as the readings are with less amps on the M2 port or what ever motor is on M2 port draws less power (current/amps).
On the other hand about the temps is that now the right motor got warmer than the left that was before the swap but (I'm thinking ) the motors now rotated the opposite direction i say that the one that rotates CW GETS WARMER than the other that rotates CCW . Just a thought ...

 

did you notice in that hidden menu above that the two motor columns seem to update independently ?

when I tried it on my first remote - they were always "out of sync" by 50-150 rpm and partial amps - I just concluded that the remote was getting this telemetry information one motor channel at a time and there was some variation from one second to the next producing the differing results...

 

So i did an other test
Now with the motor ports swaped as before i run the motors on reverse so they run as they were before i do the swap on the ports . That the I noticed is, again the left motor got warmer by 3 degree Celsius than the right. so my thoughts now are stronger that the motor that rotates clockwise gets warmer that the other that rotates counter clockwise maybe becuse of how the motor is made the one that rotates CW gets warmer and of the same motor rotates CCW works cooler ....

 

Yes I noticed that ! Each channel gives different info at the same time ... only for just a tiny second are the same ... also I noticed that on low rpm the motors have a lot of divergence than on full throttle that are most of the time very little divergence.

 

Now my last test ... I confirm that with the default port setup (unswaped) I tested the temps by running the motors normal and then on reverse and I found that when you run the motors on normal the left gets warmer and when you run the motors I reverse the right gets warmer which these info tells as that which ever Moro rotates CW GETS WARMER .
If someone can measure the temps with an infrared thermometer, it would be nice to give a confirmation on this .
Thanks a lot !

 

Do the motors have inbuilt fans? If so these fans may be more effective running in a particular direction...

 

Nonth

no they don't have any fan inside ..

 

how do you get into this screen on your remote ? good trouble shooting.

 

My tonight's ride was 9,1 km from 100 % battery and at the end the battery with full throttle at fast mode was 14 %. The temps difference was quite big at 16 degree it was about the left 46 and the right 30 at outside temp 14 degree of Celsius.
By the way at the end of the trip without pressing the throttle trigger the battery was 50 to 58 %.
Just to inform you.... )

 

I forgot to mention that all the route was inclined from 5 to 25 percent.but mainly 20%
