Predicting motor failure based on relationship of motor pair characteristics

摘要

A system and method of predicting motor failure based on relationships of motor pair characteristics, such as temperatures. A motor pair detection module receives temperatures for each motor of a motor pair over a predetermined window. The motor pair detection module 460 determines whether at least one of the temperatures of the first motor and the second motor exceeds a temperature threshold during the predetermined time window. The motor pair detection module 465 further determines whether the temperature of the first motor differed from the temperature of the second motor by at least a difference threshold for at least a percentage threshold of the predetermined time window. Based on the determinations, the motor pair temperature outputs an alarm signal 475 to indicate a potential impending failure of one of the motors of the motor pair. The motor pair may be for a mining machine.
