Emulation of a Permanent Magnet Synchronous Machine with Stator Winding Fault

Permanent Magnet Synchronous Machines (PMSMs) are used in electric vehicles because they are compact, highly efficient, and have high dynamic performances. High reliability and fault tolerance are required for these applications. The electric machines when exposed to high temperature, vibration and chemicals suffer from various faults. One of the common and catastrophic faults in PMSMs is the inter-turn short circuit fault in one stator coil. Hence it is required to study the PMSM behavior in the event of this fault. The Power hardware-in-the-loop (PHIL) emulation of a PMSM with Interturn Short Circuit (ITSC) Fault has not been done in the literature. This paper proposes to do the PHIL emulation of a PMSM with ITSC fault. The analytical model developed is used in the emulator setup. A comparison of the results obtained in the hardware setup for the emulator is compared with the simulation results obtained in MATLAB.
