1. A method for preventing motor operation in motor positions having unbalanced phase currents, the method comprising:
receiving motor velocity data; and
in response to a determination that the motor velocity data indicates that a velocity of a motor is below a threshold velocity:
calculating a thermal metric corresponding to a phase imbalance of the motor;
identifying at least one thermal mitigation parameter based on the thermal metric;
generating at least one thermal management motor position command based on the at least one thermal mitigation parameter; and
selectively controlling the motor according to the thermal management motor position command.
