Electric Motor Emulator Aided Motor Drive Design: A Case Study Under Resistance Unbalance Scenario

This study aims to emulate the Surface Permanent Magnet Synchronous Motor (SPMSM) under the resistance unbalance scenario using the Electric Motor Emulator (EME) and subsequently provides a verification case for motor drive current controller design with EME. The paper first introduces and derives the resistance unbalance motor model for the model current calculation in EME. Then, the Dual Synchronous Reference Frame (DSRF) control method is employed to effectively regulate the positive and negative sequence current individually. Finally, through the utilization of the EME-based motor test-bench, the motor drive control verification is conducted, demonstrating that EME facilitates easy and reliable verification of motor drive designs.
