I am having a prob with one of my motors. It used to have the low end torque to push the car. Now it only turns the wheels when they are in the air, not on the ground. Who knows. It used to make the car go extremely fast, now when the car is on the ground it won't turn the wheels. Lift the car in the air, they go just fine.

Any ideas? Thanks.

Maybe your motor brushes have worn out to the point that it is not pressing tightly against the commutator. Try replacing the brushes and see what happens.

Forgot to say - this is a sensorless brushless motor.

Thanks for the input. I now think the motor is fried. I am going to take it back to the factory and get a new one.

Cheers.

Thanks - But it is not a diff issue. Nothing wrong with the car itself. Just the one motor. So this coming week i will drop it off at the factory and get a new one.

My Feedback: (1)

Thats odd Keith, I have never heard anything about brushless motors just dying, bearing dying yeah but never the motor, how many cells were you running?

At first only 6 - I was using it on my Schulze ESC before it blew and it was doing this. I have a new ESC now and still does it.

Hold the car in the air and all is fine, put it on the ground and just jerks and does not go at all. put my Lehner back in and all is good and works.
