Adding to Dale's post...
The epoxy coating in and of itself cannot protect this problem from occurring. The vibration of the motor turning, heat cycling during operation and movement within the windings will eventually break through the enamel coating used to insulate the motor wires. The breakdown at the very least will cause the case short and as stated as more windings breakdown, current flows through the armature and from the armature to the case. As heat builds up for these conditions, further deterioration will occur robbing motor power and drawing higher currents. Sorry guys, I thought Banebots had solved the issue and it was behind us.
