1. A method of predicting motor failure comprising:

  • receiving, by a motor pair detection module, a parameter of a first motor on a machine for a predetermined time window;

    receiving, by the motor pair detection module, a parameter of a second motor on the machine for the predetermined time window;

    outputting an alarm signal, by the motor pair detection module, upondetermining that at least one of the parameters of the first motor and the second motor exceeds a parameter threshold during the predetermined time window, anddetermining that the parameter of the first motor differed from the parameter of the second motor by at least a difference threshold for at least a percentage threshold of the predetermined time window.
