1. A system for performing diagnostic testing on an electric machine, the system comprising:

  • a diagnostic unit coupled to the electric machine and configured to retrieve from the electric machine retrieve or to instruct the electric machine to send a set of sensor measurements to determine a state of the electric machine, and including;

    a processor; and

    a memory stored thereon a set of memory modules, which when executed by the processor, cause the processor to perform operations including;

    receiving the set of sensor measurements being operational data, from the electric machine,generating, based on the operational data, a first set of diagnostic data, by executing a first memory module being a non-adaptive module from the set of memory modules,generating, based on the operational data, a second set of diagnostic data, by executing a second memory module being an adaptive module from the set of memory modules, the second memory module including an adaptive routine including a set of parameters associated with a diagnostics model of the electric machine, andeffecting, based on the operational data, the first set of diagnostic data, and the second set of diagnostic data, in parallel, a change in at least one parameter from the set of parameters, wherein an existence of a fault is determined using both the first set of diagnostic data and the second set of diagnostic data.
