    Abstract: A modular framework for data import/export in an application that allows modules/components to be independently developed for importing and exporting data related to specific entities, including the handling of dependencies between entities. The framework is metadata driven which allows new entities to be introduced in the application with new modules for importing/exporting data related to those entities, without updating modules for exporting existing entities. Each type of entity is defined with a schema that represents the logical entity such that the entity is agnostic as to how the entity data is stored in database tables. A master configuration file is created for the application that lists each entity that can be imported or exported by the application, and defines how the framework imports or exports the business entity. Additionally, dynamic batching is provided to divide large datasets into multiple batches for suitable consumption by consumers of the exported data.

    Abstract: A system and method for determining rotor speed of an AC induction machine is disclosed. The system is programmed to estimate a rotor speed of the induction machine according to a linear speed estimation algorithm and based on name plate information (NPI) of the induction machine and parameters of the AC induction machine during operation thereof. The rotor speed estimation system is also programmed to estimate a rotor speed of the AC induction machine according to a frequency-domain signal processing algorithm and determine if the rotor speed estimated thereby is valid. If the rotor speed estimated by the frequency-domain signal processing algorithm is valid, then a tuned rotor speed of the AC induction machine is estimated according to the linear speed estimation algorithm and based, in part, on the rotor speed estimated by the frequency-domain signal processing algorithm.

    Abstract: A system and method for determining electric motor efficiency includes a monitoring system having a processor programmed to determine efficiency of an electric motor under load while the electric motor is online. The determination of motor efficiency is independent of a rotor speed measurement. Further, the efficiency is based on a determination of stator winding resistance, an input voltage, and an input current. The determination of the stator winding resistance occurs while the electric motor under load is online.
