ABSTRACT:
Certain exemplary embodiments comprise an computer readable storage device having instructions stored therein that are indicative of reducing slow roll electrical runout value of a shaft of an electric motor, the shaft having a runout sensing area; the instructions including determining an electrical runout value for the runout sensing area; rotating the shaft; determining the temperature range and time interval for heating the runout sensing area of the shaft sufficient to reduce the electrical runout value; and heating the shaft sensing area during shaft rotation at the calculated temperature range for the calculated time interval.
