Method and system for diagnostics and monitoring of electric machines
A system for use with an electric machine is provided. The system includes a processor and a memory comprising a set of memory modules, which, when executed by the processor, cause the processor to perform certain operations. The operations include receiving operational data from the electric machine, and generating, based on the operational data, a first set of diagnostic data, by executing a first memory module from the set of memory modules. The operations further include generating, based on the operational data, a second set of diagnostic data, by executing a second memory module from the set of memory modules, the second memory module including a set of parameters associated with a diagnostics model of the electric machine. Furthermore, the operations include effecting, based on the operational data, the first set of diagnostic data, and the second set of diagnostic data, a change in at least one parameter.
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, and

2. The system of claim 1 , wherein the sensor measurements include at least one of voltage, current, temperature, vibration signature, and insulation integrity of the electric machine.
3. The system of claim 1 , wherein the effecting is further based on data received by the processor from a remote terminal, the data received from the remote terminal being associated with an assessment from an operator.
4. The system of claim 1 , wherein non-adaptive processing performed by the non-adaptive module is based on a physics-based model of the electric machine.
5. The system of claim 1 , wherein non-adaptive processing performed by the non-adaptive module is based on a finite-element-analysis (FEA)-based model of the electric machine.
6. The system of claim 1 wherein non-adaptive processing performed by the non-adaptive module is based on a non-learning-based model of the electric machine.
7. A method for performing diagnostic testing on an electric machine, the method comprising:
coupling a diagnostic unit to the electric machine and receiving from the electric machine or instructing the electric machine, by the diagnostic unit, to send a set of sensor measurements being operational data to determine a state of the electric machine;
