Default Motor and battery connectors getting hot

Well i over tempted my motor earlier today. novak 17.5t with a tekin rs running nanotec 2s lipos in a Xray T4.

Motor got to 105 degrees celcius. Now if i try to drive the car the motor and battery positive connector get very hot in a short amount of time.

Now im assuming my motor has melted causing a dead short? Is that correct or could it be the esc has fryed aswell?

Thanks
Matthew

to test the esc, try another motor.

if you have overheated the motor, its possible you have damaged a stack in the motor. To test that take the motor out and turn motor shaft by hand. you should be able to feel 6 distinct points of cog in one full revolution of the motor shaft.
If there are less than 6 or some feel a bit mushy/odd compared to the others then the stator is toast and will need replacement.

Bad connectors can cause these problems too!

Poor solder connection, broken wire, bad bearing in the motor, binding in the drivetrain, or debris inhaled by the motor can all cause this. Swap motors with someone and see if it heats up in his car.

All good info here. Not to dismiss what has been said here, but Perth is going thru a bit of heatwave at the moment. The last week has been pushing 40-41 degrees C. (about 105F).

How many LED's on the RS. 1-3LED's Normal. Sure RS temp Thermal shut off or overtemp will kick on. Wires get hot if gauge wire too small. Overheating motor could be caused by gearing, How much braking, and Drag brakes. Driving style.

I'm going to pick up a new motor.

The same setup has been in the car for about 4 months and done a few race days so it been put through its paces.

I've opened up the motor an the copper on the stator has melted into the plastic cover on the stator so I'm 100% sure it's a motor issue. Now I just hope it hasn't hurt the tekin or it will be a while before I can race again.
