This is an unacceptable condition in a motor, and many teams have found that their motor(s) are shorted this way. Banebots has not offered to replace them.
Wait, FAILED? As in NOT a factory defect? If a motor is not shorted out now, assuming the possibility of developing a short is a significant issue, what are the chances of it shorting out during the season?
