Abstract
Described herein are techniques that facilitate the prediction of the end-of-life of a direct current (DC) motor of an apparatus. The described techniques include tracking end-of-life indicative motor-response values of a DC motor based on an applied-voltage value at its corresponding specified speed of the DC motor when the motor is engaged, in response to the determination that the tracked values exceed a range of acceptable operational values, a health-status notification regarding that DC motor is generated. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
