How to cosider copper loss in the mathematical dynamic model of PMSM?
Best insight from top research papers
Copper loss is considered in the mathematical dynamic model of PMSM by using equivalent circuit models (ECMs) that take into account the core loss and stator copper loss. The widely used ECMs of PMSM typically ignore the core loss, which can be significant and exceed the copper loss in certain speed ranges . To address this limitation, a generalized per-phase ECM of PMSM with predictable core loss has been proposed. This ECM topology and parameter identification method enhance the prediction accuracy of both the no-load and load core loss, allowing for separate analysis of hysteresis, eddy current, and anomalous loss . Additionally, fault-tolerant schemes have been developed to optimize the fault-tolerant performance of PMSM drives, reducing copper loss without increasing torque ripple . Overall, these approaches improve the accuracy of the mathematical dynamic model of PMSM by considering copper loss and its impact on motor performance.
