Abstract
This paper presents the systematic design and implementation of an Electric Motor Emulator (EME) for a sixphase Permanent Magnet Synchronous Motor (PMSM). Unlike conventional motor test platforms that require physical motors, the proposed EME reduces cost, improves repeatability, and mitigates development risk. A six-phase PMSM model is established using the dual-DQ transformation, while the hardware architecture employs six half-bridge inverter modules with L-type coupling circuits. A digital signal processor (DSP)based controller with current-mode control is implemented to ensure real-time stability. For numerical computation, a trapezoidal-leapfrog integration method is adopted to simulate motor current dynamics efficiently. Both simulation and experimental results validate that the developed six-phase EME can accurately reproduce current and speed responses of the motor model under step response and four-quadrant operation. These findings confirm the feasibility and practical applicability of the proposed EME system for six-phase motor drive testing and development.
